It does seem like something that would happen with a bad ground but I'm pretty confident in the grounding. I grounded both the chassis and Metra side grounds through individual wires and lugs down to the shifter bolts. All connections are soldered and heatshrinked.
Here's the button setup:
Button *** Function
Seek + *** Volume +
Seek - *** Volume -
Source *** Att (mute)
Volume + *** Seek +
Volume - *** Seek -
It's a base, non-Bose car. The thing that seems strange is that all of the controls work as I set them up to. My hope is that an update to the module will help. If not, I'm thinking bad module. Any other suggestions?
