I have an old droid 3 that I dont really use anymore. I had the idea to use it as a gps unit in my old truck. My question is if theres any way that I can use the gps services (google maps or a different map service) without having to use cell service or wifi? I am willing to root or modify the phone to make it work. As I said it just sits in a drawer now.
which is rooted as well.
