Garmin RV770LMTS vs. Garmin dezl770LMTHD


lockmup68

Recommended Posts

Years ago, I pre-ordered a Rand McNally 7710RVND. Once it arrived (months later than promised) it was CRAP. Bad hardware, bad software (especially for Mac OS users) and, on multiple occasions, tried to route me onto PARKWAYS in NY (where clearances can be LESS THAN 8'). My Super-C "infotainment system" came preloaded with RM720 software (which IS an improvement BUT, I still would NOT buy or recommend RM). I have a Garmin dezl560 too. I like that better than the RM offerings BUT, as an RVer, I can NOT enter the amount of propane I have (I can only enter "Hazardous Gasses"). I have Copilot Truck HD hardware on my iPad. Again, like the Garmin, Copilot is targeted towards commercial trucks. Copilot has come out with an RV GPS but, LARGE RVs (length and/or weight) are NOT covered. Bottom line; still NO "ideal" GPS for RVs, especially large RVs.

I think the RV model needs you to connect you phone to it to get live traffic updates.

We just bought a dezl at a TA which had a rebate.

No - it has a receiver built in to the power cable. No phone connection necessary.

Well, don't understand your con about the CoPolit. yes, it for  big trucks and long trailers. Isn't that what we have? It gets me where I want to go and keeps me off streets I should not be on.

About 5 or 7 years ago we were heading down I95 going through Baltimore and at the time we were not using an "RV" GPS.  When pre-planning the days travel I noticed the tunnel going under the bay.  Didn't know anything about it (size, restrictions...) so I called them and was told it was plenty big enough for big rigs, but we were not allowed to go through because we carried more the two gallons of propane.

The moral of the story, even a truck GPS would not have re-routed us (unless it has a hazmat setting).  Shortly after that we purchased an RV GPS and have been using it ever since.

As a side note, it's a Rand McNally 7720RVND.  It's OK, but now that Garmin has an RV model, we are looking at switching back.

We have one of those.  It's the only GPS we've owned, other than phone or iPad.  I dis-like it.  It's cumbersome to use and has hosed us many times.

We used to use a Garmin and liked it much better than the Rand McNally.  And now that Garmin has an RV version...

Garmin RV770LMTS vs. Garmin dezl770LMTHD  ??  Both have some bad reviews on Amazon.  We have to be careful with our Garmin.  For example, in Chicago, it took us off the freeway and then back on because the freeway went around a hill and stayed on the flat but the hill route appeared shorter on a flat map.

I have pretty good luck with google maps on my phone. Except when I don't have service. It even routes us around accidents.

I just purchased the Garman RV 770. Have only used it for one trip so far. You can program the height of your RV as well as if you have propane and it will route you away from low overpasses and tunnels. It can also be programmed to avoid toll roads. It has Bluetooth to connect to your phone for calls and will even show text messages on the screen. When connected to your phone it will give you live traffic alerts and weather alerts.  It has hands free voice command. Besides finding nearby fuel stops, and campgrounds it can search for dump stations and repair facilities. I don’t think the truck version can do all this.

We use the Garmin 760 DSL (sic) Truck version. We can set the weight, height, length, what avoidances to pay attention to and which to ignore. Lots of stuff.  Cons are that if you're, for example, over length a bit, it will not forgive that even if you know that truck travel that route everyday. Finally figured out that setting the length to 64' instead of the actual 68' avoids most of that. Make sure you don't have some kind of avoidance set that isn't really needed because it will route you way out of the way to avoid it. It'll throw an extra 100 miles in there and not even blink. The other thing about the garmin units is that once you have a route established and are following that, retouting in the middle of the current route is a PITA to the point of just stop and do the route over if you have any particular waypoints you want to hit.

We like the GPS for the big picture, but the phone is easier to fool with if you're in traffic or finding something nearby.
