Mk4 intermitant problem
Guys newbie here looking for some advice please
My Satnav (X5 3.0d 2003) occasionally turns off or does not start up leaving the screen blue (rather like an 80's computer look!!) and no sat nav option
When it does this the red light on the mk4 unit does not light either
Main dealer have said it needs a new unit at £2.5k!!! Which given current market valuation of the car itself is roughly a 1/6th of its value!!!
Any ideas what the problem might be and if i do indeed need a new drive unit would be most welcome
Cheers
