I decided to go with Best Buy after market a couple weeks ago. I bought the remote start for $299 with free installation. Did all this research, talked to the GeekSquad on the phone before buying. they said it was a simple install. Took the car in a few days ago, and was told the "free install" was for basic installation only. Basically any car that needs a bypass (most cars over 2002) would be an additional $120 for the module and another 2-3 hours of labor. Total amount they wanted was approx $575- $600 after tax. I was like hell no, I might as well get the OEM from the dealer. Plus the guy was telling me I could not use my OEM fob to lock/unlock the doors while the auto start was running.
Then I found the part on amazon for $129 from Avondale Automotive and bought it. Same seller in the link above. Today they canceled my order said it was "out of stock" and relisted the item for more that the other sellers ($302). Looks like by the time I figure out how to get this installed for the price I am willing to pay, it will be summer and I wont need it.
