So had the D3 installed in my truck, installer used the Peripheral GMAH24B. I asked about steering wheel controls and he said they don't work very well.
So I've been reading and looking, are they all made by the same company? Similar part numbers.
Wiring looks simple enough but are they wireless or do they plug into something? If so what? I'm assuming the adapter box so that being said does the Peripheral unit have a jack to plug in or this this the wireless part?
