I currently have the BMW GPS mount on my 1200RT, and it just doesn't work with the tank bag. If you mount the Zumo directly to it, it is much too low to see with the bag on, and if you use Ram extensions to raise it up, it partially blocks the instruments and/or causes the BMW mount to rotate on bumpy roads because of the leverage the extension places on it. Therefore, I am looking for a new mount, and I have seen both the Techmount mirror mount bracket and the Migsel dash mount, both of which look great. So, for those of you who have these mounts, what are the pros and cons of them in your experience. I know the 1st con of the Migsel, price, but it sure is a clean looking mount. Any instrument blockage issues with it?
