Hi, I purchased an Avic Z1 on ebay (maybe that was my mistake). Anyway I got a new wiring harness from Pioneer, and when I hooked it up to 12 V power to test, it powers up fine, shows last location of GPS and touchscreen works.
HOWEVER, when I press "tilt" or any other button on the bottom I am not getting any response at all. Does that mean this is defective, or is there something I'm not doing??
