Garmin 760
Currently looking at purchasing a Garmin 760 for our Class C motor home. I know the Garmin navigation systems are not perfect but in general I have found them very useful for long distance and local ...

We have had this unit since the spring and all and all it has done well. We completed an 11,000 mile trip to Alaska this year where I had put in routes for each day and it performed well...On the whole trip, only twice did it mess up...once it was about 10 miles off on an address and the other time it said that our campground was 11 miles out in Cook Inlet :) Both issues were easily resolved before they caused any problems..or water damage!!
I always map my route out ahead of time and decide how I want to go rather than just enter an address and hope. I really like to use a GPS more for knowing about how far ahead a turn may be and which lane to choose than the actual finding where I am going aspect.
My only real complaint with it is sometimes I think that the "RV mode" is overly-conservative. It gets all disjointed on sharp curves and has been wrong on clearances on some bridges. Although, if its going to be wrong, I'd sooner it be wrong this way than the other way! In areas I know, I tend to ignore it or switch the RV mode off. One of these times, though, the "boy who cried wolf" syndrome may bite me by doing that...
part of the problem with bridge/tunnel clearances is that those numbers come from the states in many cases. And I've found that often the number posted for bridges/tunnels is the EDGE clearance, NOT lane clearance. I've seen cases where it warned me of 10' clearance. that is what the tunnel/bridge showed for edge clearance on the state website, even though clearance in the lane was 12' or more. So... GIGO. As long as you stay in your lane your ok. But Garmin/Magellen/etc. only can go by the numbers they get.
In one case, Garmin couldn't give me a route to a RV park for 12' clearance. Checked the WA state clearance listing and scratched my head. Same thing, couldn't get there from here. Call to the campground said no problem on the main highway from either direction . And I also knew that when I-84 was closed truck traffic with 13' trucks went down the WA side on tthe road I wanted to take all the time. So that is how we went, and along the way there were 3 tunnels warning of 10'ish clearance ahead. but when I got close it was 10'ish on the corners, 14' in the lanes.
so it isn't just GPS that can give you bad info.
