Best GPS for a motorhome

a garmin with the largest screen you can afford.

I guess I'm not aware of all the things that I need to know about the routes we plan like grades and tunnels and all that. we have two Garmin GPS's, one is a Nuvi 2555LMT the other is a Nuvi 65 LM, 4" and 6" screens respectfully.

Both were reconditioned and one was $113 and the other about $95.

Both have good screens and of course the 6" is easier to see but I use the 4" and the navigator uses the 6". Oh yeah, they supplement good AAA paper maps.

We have been to all 49 continental states and all but three Canadian Provinces. Never had a problem but a $300 or $400 dollar RV specific GPS may work better.

I got this one just recently for $50. It says it has lifetime maps but I'm still working that out with the map maker. Also, it'll probably depend on how long the company stays in business.

But it's OK now...you can set it up as a truck, car, or BUS. Which I did. And the route it took me on from Gila Bend, AZ to Beatty, NV worked flawlessly. Not a single misroute. It also has Canada and Mexico which were a requirement for me. Some of the US brands don't (cough, Good Sam Rand McNally unit, cough).

For $50, with a 7" screen, all the normal dodas people like makes it workable for me...well anyway, here's the link, you can check it out yourself...GPS

So far, the large screen and the features makes it a winner for me. At that price.

My old, but really cool for its time, Nuvi 3790 finally died completely the other day. So my looking at possible replacement options over the last few years brought me to order the RV770 ...

I really planned to do a tablet type GPS option and have various apps installed but in the end I opted for another dedicated GPS unit.

Buy a 8" android tablet with built in GPS sensor and download the CoPilot Free App. Subscribe to the spoken direction add-on,$9.95, and set your vehicle profile to "Heavy Truck with Propane" and you have a heavy vehicle GPS that gets frequent updates for less than half the cost of RV specific GPS.

The 760 Tom recommended has been discontinued and replaced with the 770
Both the 660 and 760 have higher resolution then the 760
They also include an improved general data-base and a display of the upcoming road profile (grade)

With the higher resolution the 660 may do you fine.

I have had the RV760LMT for two years, no problems so far. It is 1" larger than the RV660LMT which may be of some help.
