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.

Which Ipod cable are you using? I had one with a chip in it that enabled "Iphone 3G" and it would drain it overnight. It also depends on which Ipod you use. It only happened on my 5.5g video and not on my new nano. Charge rate was VERY slow using that cable on my 5.5g as well.

On my iPod Touch it will not shut off when I turn off the Avic, rather it will go into standby mode. I think you also need to turn it off to prevent the battery from draining.

I was afraid of that. I guess i"ll have to replace the i-pod battery. It should be alright for overnight stand-bys, and for longer periods of stand-by i'll disconnect it and turn it off. On my wifes older pioneer deck it keeps it charged up even on long periods of non usage.

i have the ipod touch, no probs leaving it plugged in all the time.. in fact i play poker daily and use it everyday and it always has a full battery..
