5 staRs : Viper 5902 / 5902V / 5902V 2-Way Security System with Color LCD Display.
this version of viper is amazing.
i get 5 or more short blocks range, which includes tall skyscrapers, in large cities.
half mile range in the country or in a store in the country.
this means in whatever house or building, home, kmart, drugstore, etc,
i can get alarm alert on my 2way receiver remote.
i am guaranteed any break-in comes with alert within up to half mile range or more.
i have never parked car and not receive an alert.
device will tell u when u r out of range.
totally dependable in large high crime cities.
no false alerts from garbage trucks,etc, but if you smack it with hand ,
silent alert goes to your tramsmitter., etc etc etc
buy this!!.... ten stars..... even after a year of use!!!!!

I got this off Ebay for very cheap and installed it myself. Due to the complexity, and some bad internet advice, it took about 35 hours to investigate, install, and debug. To give you an idea, the wiring diagram for my Scion Xa is 220 pages. The Viper installation instructions are about 60 pages and there were at least 20 websites with often conflicting information about the wiring. The Scion Xa is a simple car and any modern/luxury car installation would be much more complex with bypasses and extra relays.
Now that everything is in, the unit is working flawlessly. With our current 106F heat index, the remote start alone is worth it. My A/C is blowing cold by the time I get to my car. I didn't have keyless entry before so that is also a plus. As indicated elsewhere, the range is no where near 1 mile but I don't care since I have the Smart Start cellular module (AT&T). I control my car with my iPod Touch through wi-fi and can start it from anywhere in the world for $30/yr. That part cost alone cost almost as much as the alarm system.
I've got to admit there is a significant sense of pride from completing a project so complex, that only a relative handfull of untrained individuals have done it successfully. Also, my 3 and 2 year old kids love it and insist upon pushing the buttons to start and unlock the car. I have purchased the 530T window unit and soon won't have to crack the windows manually in this blistering heat.

This has been a great alarm. The range is not quite as advertised, but I easily get about a half mile range in the city. Installation took a while, but it came out flawless. The remote can be a bit confusing at times, but it becomes second nature after a while.
