I also run the R3 and the mirror mount, but instead of a mirror tap, I use the optional remote mute cable and have that mounted on my ProClip phone mount. I never have to reach to the mirror for mute. One thing to note about the R3 is the Highway/City mode. On highway, while driving in town, you will get a LOT of K band notifications from modern vehicle, all of which you can filter out if you want, Change the setting to City and the false notifications will go down drastically...and by the way, I never speed!!!! Just saying...
