idea for new application

[Guest skanna]

I have just upgraded to an SP5 from a c500. The c500 was a cracking phone, in fact the only advantage of the SP5 is that it has WiFi. It is generally slower in other respects. Anyway, I was looking for a use for my old c500. Would it be possible to hardwire into the car, so it remains fully charged, have it connected to the stereo via an AUX input so that it could act as an mp3 player, have bluetooth permanently on so that it would pair with my current phone and act as a handsfree kit, preferably remaining in speaker phone mode. It could also act as an onboard gps unit, but the bluetooth could only be used for one purpose at a time, either handsfree or for the GPS receiver, and the phone would have to be in view so it would be at risk. Otherwise it could be hidden behind the sun visor. Set your playlist and go. Is this possible?
