I went to Best Buy, the installer told me they didnt install the vss wire.
I bought the install kit, gmos 04 adapter, and antenna adapter for 136.00 shipped from crutchfield. Most installers (local car stereo shops) wanted over 200.00 for the parts, and 200.00 labor to install. If you get the install manager at Bestbuy, and work a deal they offered me a install for 150.00...provided you have the parts. I think I am going to attempt this on my own. Good Luck
