Not necessarily suggesting them in any particular order, but these are pretty popular ones. There's others, but those will give you something to look at.
I've used Compustar and haven't had any problems. Range is amazing.
I was hoping I could swap mine out for the 07 model's brain and remote and all, but they said it would "require an entirely new install". //content.invisioncic.com/y282845/emoticons/crap.gif.7f4dd41e3e9b23fbd170a1ee6f65cecc.gif
I'd like to check the wiring diagrams to see how true this is. Maybe they just want me to spend $ at one of their authorized installers to have my shit redone though.
its website* and, Compustar is nice i loved mine, but at the same time i hated it. The senors were ok, but with compustar there is no room for addons, like glassbreak or tilt, or automated window sensors.
