Thanks, but I recently had to recharge the battery since it ran down from lack of use. The battery is less than 2 years old and is the correct MBZ part with 850CCA. It took a good charge, but I don't want it to run down again. I had no problem resetting the radio and clock, and the steering reset itself when I turned the wheel from lock to lock. I'd still like some advice about the chargers or battery switch sold by PAD, if anyone can help.
