Can I use the OEM GPS Harness for my Aftermarket Install?
My ride: 2005 330ci ZHP with MARK IV HK stereo with DSP
My Install: AVIC-Z3 Double DIN unit
My problem: Cannot find pinout or wire guide for a MARK IV gps harness
I need to locate:
Speed Pulse Wire
Front (L/R) Speakers
Rear (L/R) Speakers
Can I still use the DSP or should I delete it and work around it?
Thanks for all your help!
