Lou's GPS Systems

I know they have the problem about apple products giving the company your location and traveling trails for advertising. But I’m more interested in the navigation systems in cars.

Could portable (or not) car GPS systems tell companies or even other people (like a spouse or a parent for those sneaky individuals) even if they aren’t used, just in the car??

I’m interered in purchasing a GPS system which I can change inside my home and now have cords in my car while driving

I’m interested in buying a ZoomBak GPS locator. Do you have to pay a monthly or annual fee to track them?

I’m looking into getting a GPS but I’ve never used one before. Do you use one? What kind is it? Do you like it? What are you favorite features of it? Anything you wish that it did? any info would be great, thanks!
