pioneer XM/BT/HD are they compatable
i have a pioneer DEH-p860MP in my truck and pioneer DEH-p6000UB in my car, a friend owes me $260 and has these 3 components that are new in the box. could anyone tell me if the GEX-p220XM,GEX-p10HD & the CD-BTB200 will be compatable with my head units and if so what would be a fair price for them. also any information on these would be greatly appreciated. i live in the UP of michigan and don't have a lot of options for radio stations, but i am retired now and plan on doing some traveling. i already have the ipod CD 1B100 he also has the CD 1B100 [ll] is there any dfferance in the 2 of them? thank you very much for your time.
