Yea, ironic, huh? And now I'm spending even MORE money to add the accessories I want...oh well, I got my car fast!
I haven't tried anything yet...still kind of scared, as I've never installed anything like that before. I'm afraid to start tearing the car apart or finding ways to run wires. Although, the pics in the link posted were great. I'm back to work this week, so kind of busy again until weekend, but I want to get out there and look the car over and see what I think. I think I keep hoping that someone I know will know how to do this kind of thing and offer to do it for me!

I met a friend of a friend over the weekend who is an electrical engineer and offered to do it...the next time he's up from Tennessee!!! That could be weeks... so hopefully I will get the courage to try it maybe this weekend.
p.s. The Garmin system in the Kenwood is sooooo much better already than whatever I had in my Prius! Love it!
