RE: Challenger and LoJack?
I have a Viper Alarm for my Ram, and I added the GPS tracking unit to it. It doesn't interface with the police dept like LoJack, but you can access it from a land line, cell phone or computer to track vehicle movement, arm the alarm, disable the engine and other functions. You can set it up to notify you by phone email or both. I like it because it ties in to your alarm and even if you are outside the range of you alarm remote you will still get a call via cell phone or an emailand . The website is: directed electronics.com . I like the fact that Lojack is used by the police what I don't like is the fact it is not covered in some cities or states. The viper tracker has a border feature that notifies you if your vehicle crosses the boundries of the US border. I'm still looking at alarm/tracking features for my car since the technology on my first vehicle is a few years old and we all know how technology advances. I think the viper GPS tracker is close to or maybe a little more than the Lojack and it takes 6 hours or so to install.
