I have had my f90bt in my hhr for about 1 week. I have my i-pod connected all the time, but the i-pod battery seems to go dead over night. I have to wait till I run the car for about 20 mins till the i-pod charges up and is able to play over the system. I wondering if the problem is in the i-pod itself or should the system charge it continously and it be charged fully everytime its plugged into the stereo.
