I just finished installing my new audiolink with ipod adapter. I've got a few dislikes but nothing major considering you can control the ipod with the steering wheel controls. My only main gripe is the fact that the extra 1/8 plug is not as long as the main ipod wire. I'm gonna need to get some type of extension for it. Anyways on to my question. Does anyone elses ipod remain charging even after turning the car off? I'm worried that if I leave the ipod plugged in overnight I may kill the battery.
