Ugh! Sounds like a hassle. You should just trade me your avic-z1 for my fully functional and working n2 w/adapters and harnesses, it will really be less of a headache for you.

If you previously had XM, there would be three purple wires to jump over; not two. Reason for the splicing of the wires is that the serial data link comes into the radio and then is supplied to Onstar and XM via the radio link. The Pioneer head unit does not pass this link through. There should be two purple in the 24-pin and 1 purple in the 12-pin. If you don't have factory XM, no problem.
Leave the factory XM if installed connected to power.

Did the adapter come with a relay setup that had to be wired for ignition on signal? I would have to confirm by looking at some schematics, but it sounds like the there is an incorrect wire connected and I don't have a schematic for the adapter you are using.

It is also very early...

When you say 'looped' the two purple wires, you did leave them connected to the connector as well, and connected a wire between the two purple wires.


Mute output wire from the radio, you did connect that to the cut brown wire that goes to terminal 18 of the PAC adapter? Not sure what would happen if connected to the other terminal of the cut wire.

Red from radio is connected to pin 30 of the relay? This gives you the ignition On input that is normally supplied by the BCM to the factory radio.

Need coffe to think....

Spee signal, Dark Green/white it was in terminal E of the small connector that attaches to the radio?
There are a couple dark green/white wires...

If you turn on your headlights, does the radio operate? I'm going to be curious as to what Metra says about this. I'm installing one next week myself, using the Peripheral adapters .

Without XM, I only had 1 green/white wire, sure was happy when it worked.

I just installed a double wire splice in between them.

Left the mute wire from radio disconnected, do I need to splice this in??

Yep, getting power just fine now, nav works but no sound.

Yes need more coffee.....coffee is good....

No XM, spliced the 2 purple wires in pin 24. Without the splice, Onstar wasn't working, and the 12v ignition wire wasn't hot.
