i can’t wait to do this in my car! i figure i’ll hook the phone up to car adapter, and then hide it under the floor panel or something, and then i’ll have a diy low jack that i can access from any computer with internet access. alternatively, i could just get one with the biggest screen and use it as a dashboard gps… but i’d feel more like a super spy knowing where my car is every minute of the day.
