Update

I assumed Crutchfield had gotten the harness right but after seeing photos in a "how to" thread on this forum I decided to check. The photos here showed a very different harness from the one Crutchfield shipped. That one had a bunch of wires but also, 4 RCA jacks.

So, I took a couple of minutes to pull the nav radio out and sure enough, Crutchfield got the harness wrong too. The harness pictured on the forum would be the correct one. There is absolutely no way to use the 4 RCA outputs with our nav radio stock setup.

To recap, Crutchfield sent me a bunch of useless generic info I don't need but no master sheet for a Crossfire and the wrong harness. I'd say these guys are worse than useless.
