MCS - Yeah....There's obviously something coding that's still wrong.
I popped the MMI buttons out yesterday. Surprisingly easy actually. One screw under under the ashtray, takes that part out and then the whole thing with the trim pops out. Little gearstick movement and a lot of cables to pop out but actually a 5 min job.
I managed to take it all apart and clean the board and the Start/Stop and Parking Brake are separate units!
There's an odd big heavy plug in 2" bar under there too. Key stuff i'm thinking?
Looked at the board, cleaned it with isopropyl alcohol and it actually looked fine
Quite how i code the head is the question now....I'm guessing clear off the can gateway anything it doesn't want and then see if just that module is accessible ?
My other idea was to try and pop the old CD player in and see what that does. I just have to find it
