Now that I have a phone with GPS I want to use it for everything. The only feature that would be awesome that I don't think my phone can do (or anything by default) is use another GPS system. Here's the deal, I have GPS on my phone, and GPS with my fathers car. I would like to be able when I am waiting to be picked up to connect from my phone to the GPS in his car, so I can see where he is at. Is this possible, in any which way...at all?
