Thanks for your reply David
Donor vehicle was exact same spec as my car. comfort heated seats, logic 7, night vision, rear entertainment, fridge, rear air con vents on roof lining, rear window blinds, soft close.
There has been no coding done, only the parts have been swapped including a replacement steering angle sensor. Do we have a programming expert on here?
Also, audio was working fine when complete logic 7 system was moved from donor car to mine and it worked in my car after swap as well. Car was parked up for winter/rainy months. Started it up 2 weeks ago, installed a brand new Bosch AGM battery which is the correct battery for the car. However, audio system doesn't work anymore. I can't press any icons on the screen using the idrive button.
