My husband and I have not been getting along so well the last few months and there is some cause for concern that he is not mentally with it. He has gone so far as bug my telephone and he has now checked my email. I am worried that he may be using a covert GPS vehicle tracking system in my car. I have tried to get someone to look at the car but because the title is under my husband’s name they could not legally do this for me. How can I find out if there is a system on my car?
