I didnt realize how many GMT-900 owners were on the forum. Does anyone have any pics of a new f series in a 07 or 08? What kind of harness(es) did anyone use? PAC, peripheral, axxess, scosche?
For the Z3 install into my 08 Av, I needed a PAC SWI-PS to keep the steering wheel controls, and Metra's GMOS LAN 02 interface to tap into the Av's system to retain OnStar, Chimes, and all other integration stuff (including the VSS and reverse wires, no need to hunt those down and tap into them), and because it uses RCA plugs and the AVIC Z3 does too for the pre-outs (one less thing to splice). I am also using the stock amp and sub for now (new Pioneers in the doors though). Still, pretty deep install for me (put a Pio XM unit and the Pio Bluetooth unit in at the same time, plus I tied in my rear headrest DVD players/monitors while I was at it.) Lotsa wires, lotsa swearing. Got er done though.
