Need some advice, started off with no video on screen but sound only on the right side. Range rover looked and said video module and dsp needs replacing.
I have replaced these and now no power to front of screen. Range rover have now had it over 2 weeks and cant seem to find a problem.
how easy is it to replace the head unit with a double din? Or can it only take single?
Do I have to rewire the whole system or is there iso plugs for it?
Do I need to buy an amo to replace the dsp?
Any advise would be a great help as im stuck now.

I had similar issues, waste of time trying to sort out the prehistoric stock units!
This is what I did!

The double din fits fine with some plastic cutting and the use of an BMW e39 fascia!
The original speakers could be used off the headunit amp but you will require passive crossovers in each door to provide the correct frequency to the correct speaker (ie: high to tweeters. Lows to woofers)

The plug that would connect the an aftermarket double din is located in the rear so will need a BMW e39 to iso converter extended from the rear to the back of the new head unit! Also the arial is in the rear so will also need a converter an extended to the front!!
