Wow, that thing is nice. New Pioneer model? Does your unit still stay on until you open the door when you turn the car off? where did u get the 12 volt for switched power? Pic?

The gmos 1 works the same way as the gmos 4 except the 1 is for non amplified gm vehicles. The gmos-01 will also just be a plug and play install very easy and retains everything except wheel controls. For this u need a separate adapter like a PAC module. gmos-01 is the way to go very easy install will definately save u a lot of headaches.
