AlanS Posted July 13, 2017 Posted July 13, 2017 Barcobird - 2017-07-13 9:35 PM Don't know if I am missing something but my sat nav is set to coordinate format h ddd.ddddd Datum WGS-84 I have entered co-ordinates all over Europe and only once not been able to find a way point. Tonight I have entered co-ordinates from a website for a place called Alcoutim which is on the Portuguese side of the river Guadiana about 30 kilometers from Vila Real de San Antonio on the Algarve coast. Their co-ordinates N.37•2830 W 07•2829 which seems to be a digit short has sent me to place somewhere in Spain ! Am I doing something fundamentally wrong (?) The co-ordinates are not decimal - I think it should have been N37 28'30'' W 07 28'29''. I tried it on Google Map and it took me Alcoutim and what looks like in Street view a MH emptying point / Camping Ground / Stelplatz Alan

Derek Uzzell Posted July 14, 2017 Posted July 14, 2017 tonyg3nwl - 2017-07-13 7:38 PM ...The worst problem that I found with satnav is having set up a route with waypoints, and discovering for various reasons, road works etc, being unable to actually hit the waypoint, and being constantly nagged to turn back at next junction, to insist that you pass the defined waypoint. It doesn seem sufficiently clever to realise that you are getting nearer to the next point , so might be taking a small short cut... Can’t you get round that by using Garmin’s “Taking a Detour” feature? (I admit to having never tried this with waypoints, but my Nuvi 2559LM’s Owner’s Manual seems to suggest it would work.) There’s a near universal tendancy to anthropomorphise sat-navs - they are not ‘clever’ (yet!) and there’s not a tiny man (or woman) inside the device offering guidance. If the mapping data are wrong (and there will always be errors) the routing will be wrong. If the logic of the software is irrational, the guidance will be too. The potential for a sat-nav to be ‘wrong' occasionally is enormous, so a one-in-a-thousand error-rate must surely be considered pretty good. I just want to go from A to B without this involving a incandescent row with my wife who has many skills but not map-reading. If my Garmin sat-nav once in a while suggests that I turn on to a road that’s non-existent, or fails to warn me of a roundabout that has been recently constructed, I can easily live with that.

This has happened to me , I have thrown in a waypoint along the route and unless you hit it exactly (I have been within 50 meters of one) the damn thing keeps nagging you to turn round and go back. Eventually when you are nearer to the next one than the last one does it shut up. I have a female voice (lol)
DJA Posted July 14, 2017 Posted July 14, 2017 Brian Kirby - 2017-07-13 6:29 PM I can confirm both these faults on the current mapping using MapSource. They are mapping faults and it appears someone at Navteq has mapped The Drive as a through road whereas the road is signed as for residents only, and it looks as though the turn to the B260 to Longfield has been mapped as a no left turn (possibly roadworks when the mapping was executed?). If you reverse the route it merely turns right from Longfield Rd to Wrotham Rd, as one would expect. The Garmin can only follow the roads as Navteq have mapped them. You can notify Garmin of mapping errors via their website and they should get rectified on later issues of the maps. However, I wouldn't worry unduly. We have used Garmin sat-navs (2 to date, a Nuvi 760LMT and a 2485LMT) and although they do silly things at times they are generally reliable. It is always worth looking at a decent road map of any area you will visit/pass through, and relate the Garmin route to that and, if you don't like the look of its chosen route, stick in a waypoint or two to "school" it. They are clever bits of technology, but they are also dumb machines and are the victims of their program logic and the maps installed. Despite the odd irritating glitch, we've used ours widely across western, and parts of eastern, Europe over the past 10 years, and have had only a few problems - usually when I didn't follow my own advice and check where it thought we should go before setting off. It'll get you there - just don't place blind faith in its routing abilities. You've got the advantage of a far more subtle and sophisticated brain, and eyes, than any sat-nav! Hi Brian Thank you for that I have never looked at Mapsource. I will have a look and see if it is any better than Basecamp which is not the simplest of software. As I said those were only a couple of instances. If you set a trip from 9 Pescot Avenue to Chatham it does a correct route directly via the A2. However if you ask it to do a route from Bluewater shopping to 9 Pescot Avenue it takes you all the way past the A2 junction to the next one and then brings you back. It totally ignores the Northflleet exit and run to the Sainsburys roundabout all of which except for about 200 yards is dual carriage way and used by huge vehicles delivering to the large businesses in the area. I don't recommend the Car route from Bluewater either. If I ask it to do a Route to the Moffat Caravan and Camping you will find it asks you to take a left turn in Moffat into Church Place as part of a big loop. Church Place is basically a deadend. A look at Google Earth will entertain you. In fact all you do is drive past Church Place about 100yrds and turn right as we have done for years. I have told Garmin about these errors some time ago and the only change they have made is the right turn onto the A2 at the bottom of New Barn Road. A junction that has existed for at least 3 years.. Non of these particular errors have ever appeared on my Tomtoms but I am not suggesting they have not got there own mapping errors. I am sure they have. Someone was complaining the other dy that there TT was directing them off a main A road down narrow roads and refining the A road further on. I advised him that my unit recommended the A road only irrespective of the Routing type I asked it to use. Some of these things are a mystery. All the best
crocs Posted July 16, 2017 Posted July 16, 2017 Brian Kirby - 2017-07-12 6:52 PM crocs - 2017-07-11 5:53 PM On first decent French trip since purchase and am finding Fiat's UConnect great. I know not a popular view but it does all I ask/need. I particularly like the speed limit display which helps keep within current limit, especially in view of the well known Fiat speedo luminoscity. I would strongly advise against relying on a sat nav to give accurate sped limit information - unless you know it is being updated on a very frequent basis. Using the latest Navteq map update on our Garmin this spring, I was aware that many 70kph limits on approach to towns were missing. The French have been introducing these apace over the past several years, to tease traffic speeds down from 90kph to 50kph, and the mapping simply lags behind the event. The sat-nav should however give a more accurate readout of your actual speed than the speedo, so I'd rely on that and the Mk1 eyeball for staying within speed limits. I agree and that's why I said it helps keep within current limit. To be honest, though, it seemed to be virtually 100% accurate as I normally compared with real speed signs. Where it helps is that ithe speed limit box turns red when breaking the limit so a simple speed adjustment changes it back to black without relying on the Fiat speedo.

Yestereday I drove my wife’s car to a garage about 10 miles away. The route to the garage is a ’natural’, as just entering the garage’s location into my Garmin sat-nav will cause a single logical A-to-B route to be selected. As an experiment I set up a ’trip’, beginning with my home’s location and ending with the garage’s location, but setting a number of ‘waypoints’ along the route. Some of the waypoints were chosen as being directly on the route, while others were deliberately offset from the route, simulating a location that had been inaccurately set or could not be arrived at due to, say, a roadworks diversion. Having driven past the first of the latter type of waypoint, the sat-nav (as I expected) began to issue instructions directing me back to that waypoint (“Make a U-turn”, etc.) I ignored the instructions, but no matter how far I drove beyond the waypoint, nor whether I reached another waypoint, the sat-nav still continued to issue instructions directing me back to the first waypoint. Overriding the instructions turned out to be relatively simple: 1: In the right-hand bottom corner of the screen displaying the map is a square containing three horizontal ‘bars’, and touching the square causes a menu bar to appear that includes a “Change Route” option. 2: Selecting the “Change Route” option results in a list, with the top entry being “Skip Next Destination” with the destination-name showing below. 3: Selecting the “Skip Next Destination” entry causes a small map to appear showing that destination’s location (ie. shows the waypoint’s position on the route). 4: Touching the large “Skip” button on the small map removes that waypoint from the route and stops the sat-nav from issuing instructions on how to reach that waypoint. Although this procedure might sound complicated, in practice it involves just four quick screen-touches. (Obviously I can only comment on my own Garmin Nuvi 2559LM’s functionality - other Garmin models may well work differently.)

Dave C Posted July 25, 2017 Posted July 25, 2017 On the subject of Garmin sat navs, does anyone know if there is a setting to make it recognise MINI roundabouts? Dave
Bulletguy Posted August 3, 2017 Author Posted August 3, 2017 Experienced a major fail the other evening on my 760 after returning back in UK driving along the M20 from Dover when suddenly the cursor arrow just "flew off" the screen and the unit began bleeping away like mad enlarging the display by itself. I lost the routing altogether and even after pulling off at a service area to try recovering it, it refused to display correctly. Fortunately i knew where i was going and didn't really need it switched on. The unit was in night mode and that was the only difference to how i use it 99% of the time but i can't see that as being a reason. On the drive back home in a few days time i'm going to give it another chance and see if it's stabilised. If not, then it looks like i'm contacting Garmin.
Brian Kirby Posted August 3, 2017 Posted August 3, 2017 Derek Uzzell - 2017-07-25 7:24 AM..........................1: In the right-hand bottom corner of the screen displaying the map is a square containing three horizontal ‘bars’, and touching the square causes a menu bar to appear that includes a “Change Route” option. 2: Selecting the “Change Route” option results in a list, with the top entry being “Skip Next Destination” with the destination-name showing below. 3: Selecting the “Skip Next Destination” entry causes a small map to appear showing that destination’s location (ie. shows the waypoint’s position on the route). 4: Touching the large “Skip” button on the small map removes that waypoint from the route and stops the sat-nav from issuing instructions on how to reach that waypoint. Although this procedure might sound complicated, in practice it involves just four quick screen-touches. I first set up routes in the Trip planner as a series of day drives. When trips are selected from the Trip planner and "Go" is pressed, one will be presented with all the waypoints in set order, at which point one can select the first, so including all subsequent waypoints, or elect to skip the first however many, in which case the Garmin will navigate direct to the point selected, and then follow down the remainder to the eventual destination. If a diversion intervenes, as an alternative to Derek's "live editing", I pull over and stop, and then abort the route (the red cross on the RH side of the map). I then re-call up the route from Trip planner but this time, when pressing "Go", select the next waypoint after the one I have had to by-pass, when the Garmin re-calculates from the present location to the next waypoint, ignoring those already passed. I prefer to stop and re-route while static, as I have found on a few occasions that when asking mine (Nuvi 2495) to re-calculate "on the fly", it gets its knickers in a twist and malfunctions (as usual with sat-navs, at the most propitious moment - not!. :-))

Errors like telling you an addreed the occassional navigational direction error - including once being told to go the wrong way around a roundabout in France! I have a Garmin 770 Camper (the latest type) and it made a turn left rather than right error once too. But these are relatively uncommon occurences and I regard them as minor nuisances, since the devices, overall, are very clever and remarkably reliable - especially the new ones. It is foolish to simply rely on any satnav to conduct a journey for you without having any idea in your mind of where the route goes and roughly where you are in the Country as you go.

Just thankful it happened here in the UK and not during driving abroad but it was still very annoying.....particularly when it went totally out of control.
colin Posted August 4, 2017 Posted August 4, 2017 Just remembered, my older TT 'had a ment' whilst driving up auto route north of Milliu, I was expecting to exit and cut across country, so when asked to take slip road did so, only to be told to rejoin auto route, gf had lost place on map, and TT decided to leave auto route at every junction it seems, after a couple I had to get to safe stopping place get map from gf and locate us then route manualy whilst driving a van that was constantly dropping in and out of limp mode.

Also i'm curious as to what caused it. I've had an old TT "lock up" on me but that was easily sorted by doing a reset.....the Garmin just went completely mental for no apparent reason.
Derek Uzzell Posted August 4, 2017 Posted August 4, 2017 The Garmin instructions for my Nuvi 2559LM say “Resetting the Device You can reset your device if it stops functioning Hold the power key for 12 seconds” Having said on the previous page of this thread “...I don’t recall ever being advised to do something that obviously conflicts with the mapping...”, I remembered that my Nuvi advises oddly at one location in France. Going south-west from Louverné in Mayenne is an extension of the D901 that connects to a roundabout that provides access to the N162 dual carriageway. This extension was built in the last few years, is about 1-mile long and has no junctions along its length. Travelling from Louverné to the N162 access-roundabout my Garmin sat-nav advises correctly. However, returning to Louverné on the same road-extension, about half way along the sat-nav instructs that a left turn should be made even though there is no road on the left into which to turn and (to the best of my knowledge) there never has been. I can’t say I’ve ever noticed whether the map on the display shows a (non-existent) left turn when I’m travelling back to Louverné, but there’s nowhere to go (the N162 is in the way) and it would be a weird route to take even if a left-turn were there. As an ex-programmer I’m very familiar with computer glitches (and I’ve been responsible for a few myself!). Garmin’s “Real Direction” feature - that provides driving instructions based on ‘landmarks’ like stop signs - overlays the mapping software and interacts with it, but I’ve no real idea how a sat-nav’s software actually works and, as I can’t influence/change it, I don’t much care. Unless a Garmin sat-nav is not functioning (or clearly continuously functioning peculiarly) resetting the device is most unlikely to correct the occasional wrong-instruction type of error. It would be better to run an Garmin map update instead.
Barcobird Posted August 4, 2017 Posted August 4, 2017 Found this on the net but it's done at YOUR OWN RISK!!!! Note: A master reset will erase all favorites1 and will restore your device to the default factory settings. If you would like to back up your favorites to your computer, you can find instructions to do so here. To perform a master reset on a nuvi 2407, 2408, 2507, 2508, 2707, 2708 series, Camper/RV 760, and zumo 590: Start with the device off and unplugged from power To verify the device is powered off and not in standby mode, touch and hold down the power button until prompted to turn off the device Touch and hold the lower right hand corner of the display portion of the touchscreen Power the device on "System" will appear on the screen for approximately 30 seconds Remove your finger when the screen displays Loading..." Another option to perform a master reset for these devices: Touch View Map Touch the Speed icon Touch and hold the speedometer for approximately 5 seconds Release your touch when the Diagnostics Page displays Touch Clear all user data Touch Yes when prompted to "Erase all user data?" The device will automatically reset. Follow the on screen prompts to set your locale and then place your device in an area with a clear view of the sky until it acquires satellites. 1Although the master reset will erase all saved favorites, any loaded custom points of interest will remain intact on the device.
EMS Posted August 21, 2017 Posted August 21, 2017 we have just purchased (prior to a trip to Hamburg via Calais) a Camper 770 LMT-D, the Satnav behaved without problem, enabling us to find a campsite when we were fed up with all the road works on the motorway in Germany. The site was in the ADAC list as well as we checked the facilities before arriving. It was successful on the return trip finding a site on the rhine near Venlo. Our old Nuvi Garmin was having problems with the harddrive/memory causing it to lose the plot on occasions, the new unit does not make a noise so I assume that it has a built in solid state memory. The touch screen is much better as I had to use a stylus to input data on the Nuvi. All the traffic information was useful and we did not have to have the separate antenna. The voice directions were much clearer with a much better pronunciation for the foreign names/roads. Definitely progress but at a cost that hopefully will be offset by the convenience for routing, fuel stations and campsite information being displayed on the screen.
Tony Jones Posted August 22, 2017 Posted August 22, 2017 Derek Uzzell - 2017-07-14 9:09 AM There’s a near universal tendancy to anthropomorphise sat-navs - they are not ‘clever’ (yet!) and there’s not a tiny man (or woman) inside the device offering guidance. . WHAT???? There definitely is in mine. And my phone has one in the camera too, who draws pictures VERY quickly!
