Which harnesses and adapters should I get?

[dirtbagz89 10+ year member]

Hey, I'm going to be doing an install in my girlfriend's 09' Pontiac G6. She wants the Pioneer AVH-P3300BT.

She also doesn't want to lose the steering wheel controls, onstar, or the display features...i.e. the gas mileage, oil change, tire pressure....for whatever reason GM put them in the radio display. Her last car was an 04' Grand Am so she hasn't really gotten to enjoy that stuff.

I know what steering wheel control to get but I'm wondering if anyone has seen a harness/adapter that can display the other features as well???

Thanks.

No aftermarket head unit will display the Class II Data Bus information. at a minimum you need the GMOS adapter specific for your vehicle make/model/year. But you lose all factory displays. Bummer, eh? That conflict is becoming more common.

One solution is to keep the factory HU for the display and add an aftermarket HU.
