ScratchMan, was your remote start system the bi-directional? I am currently trying to install the OEM bi-directional unit, in the rear drivers cargo panel. This system has 2 antennas, one that is attached behind the trim panel and is shaped like a "T" when the wire is connected, the other antenna is shaped like a large Grey key with a 5' or 6' long ribbon wire attached. Since there are not any instructions in the kit, I have deducted that the key shaped part goes in a window. What was your system like? I am also going to purchase the OBDlink, was the software free?
