I'm thinking maps (Garman), communication from driver to passenger, FM radio or I tunes, streaming video, hands free phone, recording a trip with the camera, internet, etc....the whole shebang. If I could, I would add a backup camera also.
Our school sold off used I pads in a rubber armor case for $50. The wife has hers linked to her I phone. I use mine mostly for a camera and just got an I phone with data....was still using old flip phone.
Educate me please.
