GPS Navigation

[Semi_Retired_Gr]

Led astray numerous times by our current GPS navigator. Replace every couple of years. Time for another. Cabela's has the Garmin nuvi 2557LMT for $129.99. The Garmin nuvi 65LM for 119.99. The Garmin 55LM for $89.99. Looked at the Garmin website and see numerous models (our current model is from a different manufacturer BTW). Which would you recommend and why?

My favorite topic....

The science around RV navigation is a double-edged sword. You need it but it can make life miserable for you at the same time.

Firstly, reliable programming on the GPS itself is near impossible. The interface is not meant to plan a trip with multiple stops. You have to train yourself to think Point A - Point B and that's it. Even if point B is a gas station or stop along the way. There is no Point C.

Secondly, look at the route carefully. Check route using a 2nd reference, possibly a 3rd. I use the Rand McNally truckers map (laminated) to verify at a 20,000'view, then use Google Earth to get down to the side road details.

Thirdly, and most importantly, Do not expect to buy a software package to set up your trips and then export to your GPS. Nothing but a pit of frustration. They all do a great job at selling, poor in practice.

So, that said, I have a Garmin 760LMT. It works OK, does not crash, but not 100% reliable. For example, I am at an RV resort right now that is 200' from the highway. There is an on-ramp at the highway going North. This exit is famous as a truck stop. Garmin has me going south on the highway for 2 miles and turn around to go north, go right past the ramp I should have taken in the first place. It has done this 3 other times in different places. Almost like Garmin does not recognize the northbound ramp. In July, took me down a side road with a 4 ton limit. I have a 46,000lb MH.

All I can say is that, from what I have read, it is better than the rest!

Good Luck!

don't cha just hate when the map catches fire and leaves you stranded?

This is addressed to the Men not the Ladies. We all know how to run everything we purchase, no need to read the manual. We also never review the route, just trust in that mile portion of the route on the screen will get us there. Read the manual cover to cover then practice and review routes(zoom out to see where we are going) and 90% of the going the wrong way goes away. And yes I have blindly gone where the GPS instructed too. One time I remember from Bakersfield to I5(I'm not from this area) the GPS said take next exit. I did and then was told a right, three lefts, a right and I was back on the four lane. If I would have zoomed out I would have know just keep on going or if I had familiarized my self to the route I would have known better. GPS is a lot better than a paper map at 60 mph but still only a tool and one MUST learn how to use it affectively.

As far as picking the route, most GPS units have settings to take you the "fastest" route or the "shortest" route. Mine also has settings to avoid interstate highways or toll roads. My Garmin also allows me to set up a "custom" route to take me on roads that I prefer which may not fit in to any of the other categories. In other words, if your GPS tries to guide you to roads you do not want to travel on, check your settings. If properly set up, most GPS units will guide you exactly where you want to go. If not set up properly, you may end up taking a route that is great for an automobile, and not suitable for an RV.

Which one of those settings tells the GPS to select dirt 4wd roads? Many of these problems are not in the user settings.

On my Garmin, I can select an Off road setting under "Navigation" "Preferences". This will route me to "Off Road" trails that I guess are mapped on government maps. I can also select to avoid unpaved roads. I'm sure it all depends on what type of GPS unit that you have as to how many options/choices you have.

Being led astray may not always be the maps. I have had my GPS units (various brands over the years) pick routes at times that just don't make sense. The correct roads are all there, but something in the programing leads it to pick a bad route. I had one GPS that would never program a route over the Pacheco Pass, Highway 152 in California. I live east of that pass and a lot of things I want to go to, like Monterey and Santa Cruz, are on the other side and the GPS always wanted me to go all the way North to Highway 580 and then come back down. Which ever side of the mountain pass I was on it would do that. And it would keep recalculating and trying to get me to go that way until I got onto the Pacheco Pass and then it would recalculate and tell me to go straight ahead and cut 100 miles off the route.

Some friends and I ride quads up the mountains just below Yosemite. There is a forest service road we usually park out trailers at and start from there. At the start of this dirt road is a sign that reads, "You can't get to Yosemite this way, don't believe your GPS." Actually you could get to Yosemite that way, but only on a Quad or a good 4wd like a Jeep. One day we asked a guy that lived up there about that sign. He said one of the big car rental companies out of SFO had GPS's that would pick that route to get to Yosemite. So tourists from all over the world would get in their rental car and program in Yosemite and end up on this dirt road. And he said many of them would trust the GPS and keep going until they got stuck. He said he had used to his back hoe to pull out at least 10 and another neighbor had pulled out at least that many too.

Not only do you have to make sure your maps are updated, you have to make sure the thing is picking you a good route too.

this is a good point. we've been using a GPS device in one form or another for many years now and while rare there have been one or two occasions where the GPS lost it's mind and routed us thru the inner city or down a dead end road. the first time it happened taught me to always review the route before embarking on it.

Stand along GPS units (Tom Tom, Garmin, etc.) sure seem to be a dying thing. And I read about FAR more complaints with them than apps or online GPS programs. I've been using Waze (owned by Google) for a couple years and it's been about 99.99% perfect. Anything is capable of failing... even a paper map can catch fire 🙂 Or become outdated. So, cross checking when you're in unfamiliar territory is always wise.

Thanks for all the responses. I appreciate each of you taking the time and providing your perspective.

Matt, have you tried the 2557 for caching? Looking for a unit to do double duty

You can set the Garmin for Shortest Route, or Quickeset Route - they're 2 different things. You can also set it to avoid certain roads to further customize the route.

Gary,

Were I you, I would go right for the 2557. And, there are some reasons. The 25XX has a better receiver and a better routing algorithm. The larger memory also allows more other data to be stored.

I get asked this sort of question a lot. Maybe because I used to carry a job description of "Navigator". We have had more than a few for personal use. Not counting marine and air specific, that makes about five over the last 15 years. Some just got outdesigned, one died and three are still in service.

I have a 52LM, and by their specifications would stay away from the 55 as the routing algorithm is not that good. It also has no coverage of Canada or Mexico (if that matters).

We also have a 2595LMT. This is a much better unit. The traffic function is problematic as few places that we traffic have the service available. When it is, google maps often knows about it first. I have never even tried out the Bluetooth interface.

The oldest unit is so old that flints are hard to comeby (oops - wrong technology). It does still work and serves well for Geocaching, but not over the road.

I have a few Garmin GPS units and even tho I get the updates as soon as they come out, that does not mean that they are all going to be perfect. There is one RV park that we go to almost every year and for the past several years it has shown it on the opposite side of the road and about a block away from where it is actually located. Our own house shows up as three houses down on everyone's GPS that has tried to find us. As mentioned, a GPS is a good back-up for an up to date road map and for your own eyes.
Only once has my GPS taken me down a road where I got in to trouble. Turns out it wanted to take me over a narrow bridge with a 5 ton load limit. I didn't want to test the bridge since I was way over 5 tons and just turned around and went back until I could loop over to my destination.
From what I understand there are only two sources of map data and TomTom and Garmin each use a different database. For that reason my wife uses the TomTom as a back-up to the Garmin that I use. Between the two of them, we eventually get to our destination but they don't always agree on the route.
