Not installed yet. Just bought it. Im still thinking of a mounting location on the Hyundai. But in the Supra, I'm going to mount it here. I'm going to make a black plastic border for it so it flushes even with the console. Right now I'm thinking about getting rid of the key altogether. Just having the alarm remote, keypad, and a push button start in place of the cig lighter.
I took that little pocket with the lid off because it wouldnt stay closed and I've finally found a better use for that space.
I called Circuit City and they said they don't do that kind of installation. He said a place called Sound Advice might.
EDIT - Sound Advice does it for $150. They call it an immobilizer. It takes a few hours. Getting it installed next week.
