My Steering Wheel Controls are screwed up already after only a couple days installed in my 2006 Impala SS.
After <15min of driving, it will just start changing the "band" on me without anything being pressed...and it would freeze the screen and not allow me to press any on-screen buttons. If I press one of the hard buttons on the HU, it would unfreeze everything for a moment, but then the SWC module would start changing the band again. After I unplugged the module it went back to normal, so it's not the D3.
This problem could be possibly due to it not being the latest firmware (there is a bulletin at PAC's website) or the fact that I programmed the last 3 functions into one button in an attempt to "skip" the two functions. I hope it's not a firmware issue, b/c I did not buy from an authorized ebay seller and returning it to them (the seller) will likely get me another unit with the same FW.
Anyway, I reprogrammed the SWI-PS this AM after reading through the non-Impala-specific instructions on the PAC website. I realize I did the "skip function" wrong (you need to press the MODE button on the PAC module to skip a function). I only have 7 buttons on the wheel and I wanted my up and down buttons to change the presets, not "seek" channels, so it was necessary to skip those two functions. It works, but it seems that I didn't hold the MUTE button long enough b/c that doesn't work now.
...so I gotta try the programming one more time.
I read elsewhere (member CRXX...somethingorother) that the car should be running while I attempt the program? The instructions say to turn the key to "ON" but makes no mention of actually starting the car. I have ACC, ON, and CRANK positions for the key. Also, can the PAC module be plugged into the D3 at this time? It already is, and I don't want to have to keep taking the HU out to reprogram this damn thing.
Lastly, it's not clearing the stored info as the directions claim it should when holding the MODE button in while turning the vehicle to ON. The light just goes off immediately after letting go of the button.
Anyway, I'm going to let this fly for a while and see if this clears up my "sporadic band switching" troubles. If anyone sees what I might have done wrong, let me know.
