Start by getting a unit with the correct part number for your vehicle, as indicated in VIDA parts catalogue
And if you do have the correct part number - then it is likely to be faulty.
I trust you are aware of the nav systems diagnostic mode? However to bring that up you need to have a working remote or steering wheel controls - ie: button presses

Thanks for this. Useful stuff.
Rather than trying to find another unit, could this one not be coded to the car? The nav pops up and shows me on the map currently. The buttons and remote not working is the only issue it seems.
I wasn't aware of diagnostics, but as the buttons don't work I doubt it will work, but shall try!
