USA SPEC charging issue?

[lpaudio2]

I notice when my iphone is connected it continues to charge after the car turns off... does anyones else do this? Im concerned even without the ipod connected there is current draw and it will kill my battery.

Don't worry about it too much. According to the manual, it will charge your iPod/iPhone up to one hour then it will cut off to prevent battery drain.
