Query: Great Accessory

I've had my C340 now for almost 2 years and love it. The one problem is the suction cup that comes with it doesn't stay on the glass very well anymore. The dashboard mount is really great! I've used it in my car and minivan and it doesn't slide around at all, easy to just set down right where you want it and it stays. I wish this had come with the GPS in place of the suction cup.
