Just had one installed today sans Remote Start (Wanted $175 more, plus weather is usually mild here). Just wanted to say that it integrated seamlessly, and I love it. Definately feel more secure now, knowing that if my alarm goes off, my remote should let me know, within at 1/4- 1/2 miles. (1 mile is with no obstructions, I expect I should get decent range within a building). :D

How much was it including install?

I got the 5900, a 506T glass break sensor, and a piezo siren for the interior. It was $629 installed, and I had 10% off on parts. This was from one of the best shops on the island though.
