I also have the 7 inch Rand McNally RV unit for travel. The longer I have it the better I like it. Naturally, you still have to think when using it as it sometimes give wrong or dated info, but over all it is very useful. On the downside, screen glare can be bad, but a sunshade helps. Also the battery charging/discharging light is very small and subject to glare with the result that the battery can go dead at a bad time. The maps are updated, and you can notify RMcN of errors to get them corrected. If I had it to do over, I'd buy the same unit.

I read earlier in this thread a comment regarding east coast and propane restrictions. The only places I have ever ran into that have these are Baltimore and the Chesapeake Bay bridge & tunnel in Va. Never have seen them anywhere else. I don't need a GPS to remind me I can remember them. I use an old Tom-Tom and despite it's shortcomings it has worked well and has been reliable. Our AS trailers are not very high so I have yet to come to a situation regarding height restriction. If you have a larger and higher trailer or motor home I do think the newer ones that will advise where they are would be useful. Other than that I plan my route ahead using google maps and have my road atlas ( always nearby) and my GPS for on the road change in routes and I'm very comfortable as we travel the country. Now big rigs are a different story.

That's my story and I'm stickin too it.

See ya'll on the road sometime.

I would like to know how specific the RV data can be for the Garmin RV 760LT. By that I mean, items like the total length of our rig, width, height weight etc. My 7" Rand McNally is sadly lacking on choices for my RV description.

I like Garmin GPS units and have used them for years. I have older marine (Salt Water) GPSMap 478 units mounted on my Honda motorcycles with XM radio aviation weather subscriptions for real time superimposed weather details (red/yellow/green/clear like on television) which allows be to see the road details to possible find an escape route from developing severe weather.

The Dodge truck came with the factory GPS, so between the two GPS units and hard copy atlas, I think we have a chance to avoid a long single lane road with a dead end.

The I phone was not relevant to the question. He was wanting feedback about the 760 LMT. If he wanted an iphone ,ipad or any other apple product I feel pretty confident he would have asked about it. The OP may be like me and not want or need the tablets and smart phones and all the other technical gadgets that most people think they can't live without anymore. I for one am still a dinosaur with regards to my cell phone and plan on staying that way. Now if anyone has pertinent information regarding the OP question I am sure he and myself along with a few others would like to hear the pluses and minuses about this or any other rv specific GPS systems. If not then please don't post here because it is a waste of time to go through info not specific to the question. If you want to post about ipad, iphone or whatever else then there are plenty of post you can go hang out on. Thanks Dale

Haha.... I've been doing this with my phone in my car, and frankly it's nowhere near as good as a standalone GPS unit.

1. Google Maps nav flickers maddeningly, to the point where it's unusable on my phone (Galaxy S3). Waze works fine, however.

2. Both require data connections. Waze chokes if you don't have a data connection and have to re-route (rerouting is done by server apparently); I haven't experienced that with Google yet but as I said it's completely unusable.

3. Both will destroy your battery unless you keep it plugged in. No problem, except plugging it in will also make it get very warm, which is hard on the batteries. And if you don't have a good cord, your phone will still lose charge over time.

4. On a recent 1300 mile trip, my phone locked up twice - requiring a reset both times to get going again. Not only was it unusable for navigation, it was also useless for all of the normal things a phone can do, like making calls. Nothing like realizing your GPS stopped working 10 or 15 minutes ago. I assume it overheated... see #3.

I'll continue to use the phone for trips in my car, but for the truck, we'll stick with a real GPS unit, especially with the connectivity issue. Currently we have an older Magellan unit that works pretty well, but we're kicking around the idea of upgrading it - it's now at least three years out of date and there have been several road changes that affect us. (Yes, we can buy new maps, but given the cost of those versus a new unit with better features, it's not worth it.) I'm curious to hear what others say about the unit that is the subject of this thread.

I like the features that a dedicated RV GPS provide. My Rand McNally helps me find campgrounds, truck stops rest stops, and keeps me out of trouble since it knows the height, weight, length, propane capacity etc of my rig.

I have the Garmin and so far I like it a lot. The support bracket is the best I've seen for a moho. The 7" screen is real nice. The directions have been spot on. the battery life is about 30 min when not powered. The blue tooth feature works well on ours. I have used the apps on my iphone but I like the GPS better because of the large screen and the mounting capabilities of this unit. I really like the lane designation and the speed alert.

We use the built-in navigation in the truck and a Garmin. They both have the same incorrect maps. The iPhone sometimes does better, but I don't have an unlimited data plan. I don't have a data plan for my iPad, either. A good memory is the best thing- remember that GPS took us some terrible way last year and don't ever do that again. Sometimes I think about going back to a Rand McNally road atlas. I have had the DeLorme GPS software for a laptop and a Magellan Roadmate 760 (the GPS unit in Robin Williams's RV). They had the same incorrect maps as what I am using now.

That is one great thing about my Garmin GPS units, they are consistent. The same map and direction errors are on all the different models I have that are still operational...

The marine model GPSMap 178, 278, 378 and 478 models could interface to the XM-30 external antenna that could also support an aviation weather radar subscription (seems like $209 quarterly for my two units). That information was a transparent overlay that allowed the viewer to still see the road information below the weather depiction. That allows me to discern an alternative route while riding the motorcycle to avoid the hail or worse....

Those models also supported a fathometer when used on a boat as well as set and drift for water navigation. The speed could be displayed in knots or miles per hour.

Can you please tell me - does or is your unit capable of being heard through the audio system on your TV... I have trouble hearing and am looking for a unit that will speak through the truck speakers and I can adjust the volume... Thanks JV

The Garmin marine units I use on the motorcycles have a stereo sound out capability. I just needed a typical headphone plug coming from the motorcycle audio system.

If your vehicle has the ability to connect an external audio source using a stereo headphone plug, then the sound from these type of Garmin GPS units would play over the vehicles speakers.

I am not familiar with the more modern Garmin units if they have the capability for an audio out jack.

If your TV has Bluetooth then you're in business. Mose late model GPS have Bluetooth capability and will be heard through the TV audio system.

If you don't have Bluetooth then you will need one with an audio out and hard wire it to the TV audio somehow. Maybe one of the car stereo shops can help you out in that regard.

2 easy points;
===Be sure to get Bluetooth capable, basically gives you a phone directory for the whole country. Want to call ahead and see if Walmart allows overnight parking... you've got the number.
===With my Magellan I also got the wireless back-up camera option. Easily attached to the back of the Airstream and gives much comfort while backing up.
