ok, so i got the SVXdc harness installed tonight. steering wheel controls work perfectly....sort of:
Volume controls control volume
^v buttons move selection (track or radio station preset) back or forward
Mode button switches between mode
Bluetooth controls are recognized, but don't work as labeled:
off hook and on hook buttons seem to function the same as the ^v buttons
the voice command button mutes or activates the "ATT" function depending on your settings
I'll have to do some research over the next few weeks to see if the issue lies within the H/U or the Axxess ASWC module.
The good news is, in the meantime, that the buttons can be reassigned, so if the way the bluetooth buttons are set up don't float your boat they can be changed to something more preferable.
if i can get the bluetooth buttons to function as labeled, that's dbe the icing on the cake. as it stands right now, my main goal has been achieved: to be able to control volume and skip tracks from the SWC.
