Anyone ever mount a Garmin Nuvi to your tach face with the suction cup windshield mount? I realize that you would lose the view of the tach but out on the highway it really wouldn't matter.
No, I've never done that, but mere lack of valuable experience rarely keeps me from having an opinion

. Since the Garmin can show you your speed more accurately than the C14 speedo', I think I'd put it on the left, and leave your tach readable
(as well as your ABS and KTRAC lights if so equiped). I needed to raise my Zumo up
above the gauges because I was becoming dangerous to myself and others with it down low.
