AccuTracking

Hi !
I'm really do not think this site has what I'm looking for but I am hoping maybe someone here can give me the answer to my question.
I'm wanting to buy a GPS system for my girlfriends phone. I'm not wanting a "Tracking GPS" to keep up with her but instead just want to be able to put a GPS system on her phone that she could access easily if she needed directions. I can not find anything on GPS for Cellular south service and I was wondering if there is a program that will work with this service?.
I love her to death but she can hardly go from her house to the store with out getting lost!

P.S. I did not know you could even track with a Cell phone till I stumbled across this information looking for a GPS program for her phone. Modern tech is scary now day's but amazing at the same time!
Thanks for any help!

The boost phones have telenav in them for directions..or buy a tom tom..

Thanks for the reply back. I was hoping I could just keep her phone and add a GPS program to it for her without having to buy a new phone or her having to keep up with two things when she drives.
Thanks again though for the reply.
