I purchased a Pioneer 3200UB radio. However, the head unit will not power on. I used a Metra 70-2003 wiring harness (sonic-electronix says is the correct harness for a 2006 grand prix) and connected all wires accordingly. Is there something that I'm forgetting/missing? the grand prix also has On-star if that matters? Need advice please.
2006 Pontiac Grand Prix can't get aftermarket CD radio/receiver to turn on?
