Thanks, I did a search and found the answer. Base radio comes on everytime you start car, regardless if you want it on or had it on. I will use the advise of putting the radio in aux before I shut down the car.
I also found the answer to the rear wipers, yes they do come on when you have the front wipers on and go into reverse. Even through I do not have the comfort package, my front wipers did go on intermittent when I was waiting at a red light, then they returned to normal setting when I accelerated away from the light. Today is day 6, so far my complaints are the radio turning on when I start the car and the steering wheel does not adjust up and down.
