Hey GMTnation,

First time posting here, but I've been reading through this site and trailvoy for a while, and haven't found my answer so here it goes:

I am trying to as Auz inputs to my factory head unit. It has built-in CD changer and a slave XM unit.

I bought the AAI-Gm12 (link and instructions below) to plug in between the XM unit and the factory headunit, but I apparently my envoy does not have the infamous RAP wire as it uses data to wake up/turn off the radio.

Pac audio told me via email that I would have to tap into a switched 12+ volt line in order to not drain the battery on my car.


So... Has anyone on here gotten past this issue? If so, would you mind sharing how found/tapped into a 12+ volt switched line? I would really appreciate any help!

Eh, should have been in the audio section, but no big. As for your issue, there are a ton of places to grab 12v switched, but harder to find true "RAP". Closest to the stereo is going to be right in the ignition harness, you can tap the orange accessory wire. If your squeamish of working in that area, you can tap int the fuse under the backseat for the rain sensor (should be labeled). Personally, i'd run the wire and tap the fuse for the rain sensor, but that's imho.

Thank you for your fast response!

I was thinking of doing something like that, but I wasn't sure how I would run the wire and keep it out of sight (or mostly out of sight at least). Is there a secret to this, or is it more creative problem solving at that point?

Also, does a "switched 12 volt line" retain power as long as I have the key in the ignition, or will it turn off immediately after I turn off the car?
