As far as I can tell, research wise, you have the right harness for the Pioneer system, the only likely issue is something somewhere is crossed or not hooked up...even though you do seem knowledgeable in car system installation...even the best of us make mistakes, that we can't seem to find. If you're absolutely sure everything is 100% correct...perhaps the harness is bad? Since some functions work, maybe it's possible only certain wires aren't working properly causing your issues.I've tried about 5 separate times trying to get my alpine single din installed, using the gmos044 and the aswc, my issue is I cannot get the oem screen to work.
When I first tried to install I had just done what I've always done with aftermarket headunits connect and solder the corresponding colors. originally I had cut the little ring terminal on the ground wire on the gmos, and tied it in with the other 2 ground wires, as plugging it into the 44pin connection is going to get your body ground. The radio powers on, all speakers work steering wheel volume, seek up/down and source work. The end call and call buttons do not work tho and no oem screen.
My following attemps have been taking all the harnesses apart and rewiring and reading the gmos instructions and noticed that ground ring terminal needs to be grounded to the radio chassis so I soldered a new one on and tried that. Again everything works but no oem screen.
Really quite frustrating not sure if the aswc isn't detecting the alpine radio correctly to not allow the call/end call Bluetooth buttons to not work but without the "off hook" as per instructions working you cannot get the oem screen to work. Another theory I have is looking at pictures people have posted on the forum of them with a aftermarket headunit all have the little oem screen, and I have the touchscreen with the pioneer upgrade and maybe the kit isn't compatible with that, but I don't recall any limitations on the gmos, only pre requisite was for factory steering wheel controls to get the aswc and screen to work.
Really would like to get my alpine and the oem screen working, I cannot stand the mylink radio so many bugs with it.
