I recently left my husband for assault and thought i had a fresh start. But I found out today that my car has a built in GPS through the factory installed radio/cd player that will allow him to find my car AND since we are both on the title have it shut down. Don't know if it's true but has me very concerned. How do I know if there is a GPS and if there is how do I disable it... I don't have the money for one of those finder things. Someone said if I take out the radio it will disable GPS. Any knowledge will help immensely.
