Never works

What in the world... id rather pay 300$ for a gps then use this. When the dealer helped me load everything onto the tundra and my phone I thought it was the coolest thing. Since then it will never work. It wont even show any mapping system on the stereo.. i wish I could give it a 0/5 I have tried uninstalling and re installing and still wont work.
