okay, so i bought a pioneer head unit, and i bought the correct steering wheel interface, but i'm not so sure i bought the correct data bus interface. i do not have the bose system in my '07 gp. i bought the gmos-04 data bus, but i think i was supposed to buy the gmos-01 interface. the only difference seems to be the 4 rca output cables. is there anyone that can tell me whether or not this will work for me if i just connect the 4 rca cable's wires right to the speaker wires on the HU's harness?
...any help is greatly appreciated. i have the new head unit running right now but i'm not sure the interface is working. i have sound out of the rear speakers, but it is low, and the front speakers are not putting out sound. also, when i shut my doors, that turns the stereo on for some odd reason. thanks again for any input!
