i just installed mine today

has anyone noticed that it still charges an iPod or displays a message (this is not compatible with your device) when the car has been switched off with no accessories running.

will this run the battery dead if left unattended for a period of time if left plugged in (ipod/iphone).

when the key ignition is put into accessories (cd player/stereo on) or with the motor running, all is working well with no problem with either ipod or iPhone.

this is just a general concern to find out if my car battery will be flat when i have to leave for work, or be stranded away from home.
appreciate any feedback.
