Replace original stereo/reversing camera screen

[mikeymay]

I am looking to replace the current stereo that has a tiny screen for when reversing.

 

There is a slot above the stereo so a double height unit can be accommodated. Alternatively, I have seen something that goes over the rear view mirror and has a screen fed by the camera so single height unit would be considered if this is possible.

 

I also want to get either a pivoting/dual camera to replace the current one which will allow constant rear view (to replace the partially useless rear view mirror) and/or a view of the back when reversing.

 

For the stereo I want a DAB stereo and phone connectivity Sat nav isn't required as we have a MH Tom Tom.

 

Can anyone recommend a unit and/or setup that would provide the above?

I've got a wifi reversing camera that connects to my smart phone, it's not fitted to the van yet as its in a garage and a can't get round it but it works great in the house and garden. Good range.
