What he said. My dealership quoted me $657 for programming but if you read through this thread some have gotten it for $150. It's been a while since I've researched, but I remember something about folks who do "audiologic" or "audiogalaxy" programming or something like that, which ends up programming your car for you for pretty cheap. Otherwise, there's a guy on these forums who will send you his programmer and program it online for you (through and internet connection)...forgot what his name is but he charges a bit more...still a lot less then what the dealer was trying to rape me for.

I created a somewhat "guide" to reprogramming here if you want to look at it. All you need to do is find a garage that does the J2534 reprogramming.

Good luck to ya
