Hi Paul, I found that price too on ebay but think its definately worth while doing it yourself as you can prob save around 600-800 notes by doing it this way. Im no expert and personally dont think its that hard to do, yes it involves removing seats and radio etc but its only a car at the end of the day.

If the monitor is from an x5 coding shouldnt be a prob either, Im ready to give it a blast!

Ive emailed andy about the harness he uses, ill post a reply once he responds.

I think BMW may sell the retrofit harness for a better ££ than some may think too? I may call them tomorrow if I have time.
