You can use both the OEM head unit and the aftermarket unit. When I use the GPS I listen to CD's or radio on the OEM unit and the GPS will spit out commands via a separate speaker. If I want to use only GPS then I can have it come out of the OEM speakers. I can do A/V input via composite RCA's and 4-channel RCA outs to amps if I choose.
Does your GPS program freeze alot? Mine tends to freeze about 20 minutes into teh trip, i bought a class 4 SD card to speed it up but no luck. What program does yours use? Mine uses iGo and i think it might be too resource intensive ram wise maybe.
