Well I looked at the install in the wifes to make sure none of it was hacked......actually didn't look as diffficult as I thought. I would phone a few places and get quotes.....only took 3 hrs on this one, can't think a newer one would be that much worse. I have done tons of them on Chryslers, but didn't feel like laying under the dash doing one I wasn't familier with........looking at it now, I would try it.
2 other places I did price, were over twice the price.
Can't see why it would be trial and error either, I talked to the guys for a bit to see how good they seemed before I desided to get it done, and he showed me the website they use, punch in the car, and it gives detailed pics and locations for tapping into the wiring/etc. Wasn't a future shop site, was a accessory site of some sort. Try future shop.........my best buy here wouldn't even do it, which makes no sense as they own future shop!
