Cell phone car charger...
 

i was thinking the other day, since most of us have cell phones and we all drive, mosy of us probably have a cigarette lighter-adapter car charger for your celly. Has anyone hard-wired the charger directly into the car, like hooked up the ignition, or directly into the wires leading to the cigarette lighter. I think this would be not particularly hard to do, but I dont know if anyone has thought, or done this alrady. Also, my phone has an MP3 player, could I wire it up to the head-unit, like an ipod to play thru the stereo. Just a couple of ideas I have had, but I am a little afraid to start going at wiring and not knowing it it will work. Let me know of your thoughts or possible experience.
