Best Navigation unit

I have two Garmin units. I also have Streets and Trips 2011 with GPS sensor. Besides this I have an Ipad with GPS and also apps on mine and my wife's Verizon smart phones. None of the above, with the exception of Streets and Trips, have any warning about overhead clearance.

After three years of comparing routes calculated by the different devices I have learned to rely most on the routes calculated by Verizon. It does not always give the shortest route, but when I have depended on Garmin rather than a different route calculated by Verizon, it was a mistake. The Garmin has put me on mountainous routes such as one just north of Santa Rosa, CA that limit speed to 25 mph for miles, when the alternate Verizon calculated route, although longer, would have been much safer and faster. The only drawback with the phone is that it must have a signal to calculate.

Which Garmin units do you have, the was under the impression that the Garmin RV670 did do height?

"Alerts you to upcoming road conditions
Such as sharp curves, bridge heights, weight limits, high-wind areas, descents, ascents and more to help keep you informed. Also shows trucking speed limits and mile marker information."

I have also read in PC reviews that Garmin shows ads?

Some years ago one of the gear head type mags did a study and they compared top of the line Garmin, Magellin and Tom Tom over 3 diferent routes. They gave Garmin top marks on all 3 routes.

I use Microsoft S&T 2013 myself. with the big POI file from Discovery owners that lists all the low clearance spots.

That said....... Paper maps are the only thing that have NEVER left me lost.

Neat I had never heard of that. Going to dig into their site for more info.

As for a recomendation, I think the best units are from Garmin (dezl or RV) 760 or the RAND 7720. To each his or her own on what the differences are. I would read through this RV GPS)http://www.doityourselfrv.com/rv-gps-comparison-review-best-options/) review article to get a feel for all the different fluff that you may need or not need.

Also you could search the forums http://www.rv.net/forum/index.cfm/fuseaction/search/parms/sw%7BGPS%7D%7Ckm%7Bexact%7D%7Ckl%7Bm%7D%7Cfm%7B%7D%7Cpd%7B365%7D%7Cma%7B%7D/sr/1.cfm

I have compared the dezl 760LMT
https://buy.garmin.com/en-US/US/on-the-road/trucking/dezl-760lmt/prod112211.html

to the RV 760LMT
https://buy.garmin.com/en-US/US/on-the-road/rv/rv-760lmt/prod135455.html

Price is the same, RV has my trends but does not have Photo Navigation

Bottom of the RV has this

Specialized RV routing supports RV-related restrictions in both the U.S. and Canada (customizable by height, weight, length, width)
Shows America's RV parks and service locations
Displays elevation grade of current roads while driving
Includes RV specific features such as state border notices, speed limit changes, sunrises/sunsets and mile marker info
External video input for backup cameras

Dezl has nothing listed on these features????? I talked with Garmin customer service? who vegly said the dezel has those features

We have the Garmin Dezl truckers gps. We can program the height, length and weight into the gps and hopefully it won't route us under a short tunnel. It also gives you truck stops for fuel and repairs. We like it.

Garmin has just introduced the RV760, with includes height, etc setting. Based on Garmin's solid rep, it -may- be the best on the market.

Rand also has models out there, the early models stunk, they froze, they crashed, the died, etc. The newest models may have fixed those issues.

IF, I was buying today, I would probably get the Garmin.

That being said, you can add height info to just about any GPS. Look for the Low Clearances POI at http://www.lowclearances.com/ for far less money
