Hello all, newbie here - I am about to part ex my 2014 Range Rover evoque for a 2014 LR4. The car was meant to be delivered to me on Wednesday but the garage rang to say when they started it the main screen was blank and still now they are in the process of trying to rectify it! Any ideas if this is a common fault and maybe just a case of when the battery runs flat it can cause this!? I have only paid a deposit at the minute but is already casting doubt in my mind!? Any ideas or suggestions would be greatly appreciated.
