Weak Garage Door Opener
I just got my SL on Saturday and managed to program the integrated mirror-mounted remote OK. However, it won't open the steel garage door from the outside when the door is closed. It will close the door from the outside and it will open the door when the car is inside of the garage. I tried stripping the insulation from the opener's wire antenna with no result. My handheld remote and the integrated opener in my wife's R350 both open the closed door from the outside with no problem.
Is there anything that can be done to increase the power of the transmitter?
Thanks,
Charles Taylor

Ok does it means you want to extend the power of your garage door? If so the check your battery capacity, use a slightly higher voltage battery or it may be because of low voltage!!

Problem Resolved
I removed the insulation from the opener's antenna wire and it works OK now as long as I'm close to the garage door and the mirror is pointed directly at it. I can live with that.
