so you need to tap the wire before it goes in the canbus? I guess the issue i had is that i just tapped the wire at the headunit harness. edit. or was it not bus at all? I don't have a canbus connector. Probably don't need the PAC-SWI actually, but for some reason a year ago I thought I did so I bought one. Made it easy though as it had reasonable instructions. Confusing as shit, but real obvious once you get beyond the backwards thinking used to write it. PAC -> Joycon -> PC It didn't work first shot when I had the PAC set to Alpine, but when I switched to Pio it did just fine. One of my buttons is mapped identically though, but that was probably my slip up during the programming of the PAC itself. I haven't figured out what I want it to be yet though so I am not stressed. If I need more I can hijack the cruise control buttons too, lol. Each button has Short/Long/Toggle as well. Makes the alt+tab button sweet. Windows button is necessary too, but long pressed it alt+f4 or closes whatever window you have open. Pretty much between those two Win8 makes a great interface. Using a simple front end that is XML configured outside of Navigation/MiniDSP/HPTuners to take care of everything else...including starting the listed programs. maybe my issue is with the PAC programming as you explained. I had a feeling I was really close to figuring it but ran out of patience at the time.
