I just installed my unit this weekend using the Pac-Audio CAN bus module and the SWI-PS. I did the setup and the steering wheel controls worked fine. I then updated the 310 with the new firmware and the controls no longer worked at all. So I re-programed the SWI-PS but no matter what I do now the unit does not respond properly. The steering wheel controls activate, just not what I want them to. The unit is installed in a 2004 VW Jetta.

 

Has anyone else run into this issue?
