Sorry for replying over a year later; I called my dealer and they said they did not install OEM remote starters because it was very poor value for the customer, and they said I should go to a local windshield repairs store that also installs alarm systems, stereos and remote starters. There are lots of modules necessary to work with the alarm, the chip in the key and the power windows and keyless entry. The dealer assured me that anyone who's doing this professionally wouldn't mess up the wiring and electrical.
We'll see, so far it works very well but with installation it cost me close to $600. When I requested a quote from the dealer a few years ago the OEM part was $460 + $100/hour for installation (3-4 hours), and it didn't even have the options I have with this one.
I have a 2010.
