Now ... does know where I can find a weather/vibration proof unit for my HAWG? Harley has one with its own mount ... no not going down that road with the blonde woman thing here ... but like all things Harley .. It costs you an arm and a leg Come to think of it, that blonde has cost me an arm and a leg over the years as well .....never mind.
My dad said Mom kept him awake with the constant sign reading. (Dad was kind). I took her on a trip....It drove me nuts...
I have that same Navigation model you do...worked fine in the early years, except it kept telling me to turn left when there was no left turn to take...even had a back seat nav unit that echoed the same directions and they were BOTH wrong.
Garmin is the way to go!
