I finally found something that said that if you have navigation, you have an amp... :gaah:so I get to buy another harness.
I hope you can return it for credit.I finally found something that said that if you have navigation, you have an amp... :gaah:so I get to buy another harness.
I wouldn't let it hold you back. Upgrading the head unit in the H3 is very simple and easy. Most of the work; splicing the new harness plug to the head unit wiring; can be done at the kitchen table. Jut make sure you get the correct harness. Swapping out the heads in the truck is just a few screws and plugging it in. It took me longer to run the new mic up into the OnStar mic mount in the overhead (optional) than to wire the harness and swap the heads. It only gets complicated when your adding an amp, sub, etc.That and the H3 is such an electrical nightmare that I shy away from modding it.
