I bought the iTrip that also charges the ipod. I drive a total of 40 minutes each day and I always hook up my ipod to this itrip. I was wondering if it'll kill the battery to get charged so often and for such a short time too? Also, I leave my itrip in the car. Will it damage the itrip in any way if the tempeture is low? We have snow n sh*t right now over here, so I dunno..
