I have the touchscreen 430 that came with my sport. Wanted the Alpine system but unless I ordered, they seemed be tough to come by. Any ways....very happy with the sounds in the truck, and when the kids aren't in the truck I do have a tendency to crank up the tunes.
$2500 seems high....very high.
Almost seem to think you can buy the touchscreen unit for less than 1k. One of the things I really wanted in this truck was the touchscreen and I think once you get it you'll be happy but at what cost...all depends. Other than having a factory unit, you could go to just about any car audio shop and easily get a very high end unit, possibly touchscreen, amps, high end speakers, and maybe even a sub for that price. Might be worth your time to hit a car audio place for giggles if you haven't taken delivery. Keep us posted.
