Feel like I am talking to myself here other than
@Dav-Tec lol.
But anyway, still useful to sound out and if / when I get this fixed, hopefully it’ll help any other owners or trade members if they come across this issue rather than burning hours head scratching.
I’ve read a thread on a Golf forum that someone had issues with Alpine functionality with canbus and 5F communications errors. Now as the connects2 is marketed as ‘plug and play’, I figure nothing else should need to be done. But I’m not happy with the databus signal error. I cannot clear the error unless the original headunit is refitted (rcd330). And as mentioned, when the RCD330 is connected the buttons work.
I’m going to try a new patch cable on the off chance the cable is faulty, but I doubt it’ll make any difference unless somehow the fault is in the 3.5mm cable from factory.
Seems a strange coincidence that the control unit knows 5F is not present and communicating and so the multimedia buttons aren’t working.
Telephone button and all others on the wheel work…
If I can figure out the coding on obdeleven (starting to wish I got vcds instead tbh) I couod remove 5F and replace with radio, but, others that have done that still get errors. Obdeleven doesn’t show labels for coding options in gateway, only byte / bit, so no clue what 5f would be ticked on there atm vs radio.
Also had an email from connects2, they say some if the VW interfaces come pre configured for pioneer, and jumper switch needs changing in the unit, so I’ve removed it, opened the case and changed the jumper configuration as they have requested for Sony. Will leave out of the van and all disconnected so power can drain and will reconnect, but, I’m still not confident the jumper configuration is the problem.
Cheers.
