Hi, my car didn't come with the homelink garage door opener. My friend has one in his car that he doesn't use. do you know if it can be removed without leaving a mark on his car and installed in my car? i'm pretty good at wiring things up if needed. alternatively, can I just buy one from Chrysler and install it myself or does it have to be pre-installed by the dealer when the car is new?

THANKS GUYS!!!
