What Is The Difference Between Car GPS And Car Tracking GPS?
We often hear these questions: what is the difference between car GPS and vehicle tracking GPS devices? I saw some tracking GPS that sync with 12 ( 12 channels). Does this mean they are more advanced than car GPS? Is it possible to use car GPS device for tracking? If they are identical from the point of hardware/software – can one can use maps for cars on a tracking GPS and vice-versa?

I think the main difference is the power source and the software that is loaded. Car systems will be set up to use 12VDC, and typically be hard-mounted into the car. Trekking (portable) models will be battery operated, so voltage would be anywhere from 3-9VDC. Since a person will have to carry it, the portable GPS will typically be smaller and lighter.
Regarding software, Car units will be more likely to have better information on roads, addresses, attractions etc while the hiking model will feature land features etc.
All the GPS units I have seen use as many satellites as possible. It needs at least 3 to pinpoint where you are, the more satellites it ’sees’, the more accurate it will be.
You can you a car GPS for hiking, but you will need to bring a 12VDC power supply… and car batteries are pretty heavy ; )
A better application would be to get a portable model and use that in your car, however I don’t think the hiking models typically give you turn by turn instructions.
Hope that helps.
