Hello team,

I need expert opinions on a retrofit.

I recently replaced the standard steering wheel with a Golf mfsw (1Q0419091K),
paired with a steering control module (1K0953549BD) coding 0002021.

The retrofit works, no errors in VCDS, (Address 16 - group 009) all buttons test works, but... after the radio unit (jvc with bt), I have a Connects2 can adapter interface v18, with patch lead jcv 1 key wire (brown to blue yellow...)

only the volume + and - buttons and mute work.

The others don’t… no answer call, no track change, no source change...

I don't have cluster with MFD, is a lowline cluster with no temp gauge, can gateway is genuine...

why do you think that is?

I’m stuck, no solution for my problem. Ideally, it would be to do a cross-test with an original factory radio to see… (RCD - RNS) I would need to find one to borrow…
