YEP, I'm wanting to know about the devices that track the vehicle if it is stolen. I think there is some type program for your computer so you can see where the vehicle is located.Larry are you talking about a device to track the car if stolen or one to give driving directions?
Is that in your Chev? Where do you hide it?I have used a TomTom 300 for several years with no problems and it's very easy to use. I also have the TomTom GPS software on my Iphone and it works very well. I use their optional Iphone/GPS cradle in my car which adds a booster antenna to the Iphone GPS and you are able to call and receive calls and play all your stored itunes while using the GPS.
these would be active all the time but it is a portable unit. it charges up with a charger in the lighter or a wall plug. all you need to do is tie in a hidden type lighter receptacle (say behind the glove box) and keep it plugged in. but you could also move it to another vehichle. I know someone that puts one in his racecar for when he goes to an event and leaves his car at the track overnight.I would want one that is active all the time.
