I have recently completed a retrofit of the RNS 510 (1T0 035 686 E), 9WZ bluetooth unit (3C8 035 730 D) and upgraded the CAN gateway (7N0 907 530 M). Everything is working nicely now except for some minor details, mfsw being one of them.
The car is a 2005 Volkswagen Golf 2.0 TDi with the red MFD and 2005.5 style mfsw buttons. The vol+ and vol- buttons have always worked and still do, but the prev track and next track buttons do not... well, sort of. If I tick both "Shortpress Steering Wheel Buttons Installed" and "Communication Instrument Cluster via Operation and Display Protocol (BAP)" in VCDS then the buttons will work, but I loose the highline display so that is not an option. Also, going to the Audio menu on the display and using the wiper stalker buttons to change tracks - as I have seen suggested other places - appears to do nothing under any circumstances.
However, if I do a cold boot or reset ( < + > + star) on the head unit and wait until the music starts playing I am able to use prev track and next track as normal for about a minute. After that they are back to not functioning. I noticed that they stopped working at the exact same moment as my MFD started displaying the compass etc. Any advise on how I can get these buttons working permanently without enabling BAP?
