I just installed the JVC KW-NT800HDT and AXXESS on my 09 Touring w/ Bose (w/o Navi) and auto-programming of the AXXESS got the volume buttons, like most people. It also made the phone hang-up button the mute button on the head unit for some reason. So, I did the manual programming (tried 3 times) but can't get the JVC to recognize any of the other buttons (even track next/previous). The AXXESS shows it's receiving a signal from each of the buttons when manually programming it (the LED lights up), but they don't do anything with the head unit.
I know some people said you have to mess with the bluetooth module in the trunk (jump some wires), so I took all that apart, but my connector doesn't match any of the diagrams / pictures (both from AXXESS or on this forum (like
this post)). For each of the 3 connections that need to be made, one of the wires that's involved isn't there. (I'm going by pin locations, not colors.)
Do the other buttons on the steering wheel rely on that bluetooth module in the back? Is there some trick to getting them to work? I'd love all buttons, including the phone ones, but even track next/prev would be really nice.
