when they come out with a stand alone gps that shows your route like this google image then we would have a great gps unit. what would it take for memory to hold satellite mapping of the usa a terabyte?

It's nice to have that image available and it is useful info. However that image will not guide my Combo to the CG as well as my dedicated Garmin GPS.
Never trust any GPS 100%. Use Google maps and paper maps to become familiar with your journey.
Google maps alone can cause just as much chaos as a GPS alone

Has anyone yet tried the RV 770 LMT-S?
I'm interested in it as a replacement for Street Atlas. I like the idea that the 770 is compatible with BaseCamp, so I can lay out the day's driving in detail on a laptop and then download to the 770. A plus is that there is a Mac version of BaseCamp, so I wouldn't have to mess with Parallels and Windows any more. Of course, if it doesn't work well, then buying it is a no-go.

I'm a long-time Garmin user and have always been impressed with the different units. Prior to buying the RV 770 LMT-S I had used a nevi 3590LM as. Although the 3590 still worked great I was impressed with the list of RV specific aspects of the RV 770 and also liked the larger screen size. Let me say right off that the RV 770 has been a huge disappointment. I'm sure it's all software related, but that's part of the overall product. The RV-770 consistently directs us the wrong way. By this I mean the voice guidance is not the same as the route shown on the map on the device. For example, if you look at the map you can see the colored route line might be correctly showing a right turn, but the voice guidance says "turn left". Since I rely on the voice guidance when driving alone, I can't catch these mistakes sometimes until it's too late. One time the incorrect direction of turn on the voice guidance actually tried to turn me the wrong way on a one-way street. Another big issue with me is active lane guidance. Going through large cities with several lanes and interchanges it is important to me to know well ahead of time which lane(s) I need to be in because as we all know changing lanes quickly in heavy traffic is not always possible in a larger motorhome, especially towing a car. The RV-770 is very late in both the voice guidance for these changes as well as the pictorial of the lanes.

If you're thinking that this is normal, I can tell you that on our latest trip (2400 miles roundtrip) I also setup my old 3590 and the software in it did NOT make the same errors as the RV-770 and ALWAYS displayed the lanes I needed to be in way far in advance of when the RV-770 did. Lastly, we had several instances of the RV-770 simply routing us incorrectly. Again, the nuvi3590 worked flawlessly.

There is no excuse for these things. If the software in a 4-5 year old device can be accurate, why can't Garmin do the same thing with their supposedly newer, top-of-line RV GPS. If Garmin can correct all these software/navigation errors, I still believe this could be a great device, but until that time, I will continue to also use the nuvi3590 and pay attention to it more than the RV-770.

RV in front of any number (760,660,770) equals big $ for Garmin. As mentioned many times you can't rely on the routing anyway.
I compared the RV-760 to a LMT-2797. The 760 gave bizarre routes and dead wrong turns in RV or car mode. The 2797 gave better routing and most other useful features at 1/2 the price. I would never trust a GPS to tell me where I could go and the routes based on inputting weight and length.
If you are operating a big heavy long rig you need to know where you are going before you start. No GPS is accurate enough to trust 100%. The Garmin disclaimer tells you that.

I am happy with the newer dezl 770 "truck" gps.. much better then most. my opinion.

I have used it on (2) 1,800 mile trips with trailer.. no errors so far.
I added the RV POI ..

I also use a Garmin 2597LMT.

jday, try changing the voice to correct the directions. I know it sounds silly but our friend changed from the female voice to the male voice and the directions were all screwed up, left being right, right being left. Going back to the female voice corrected the error.

You're right that it sounds silly, but it is worth a try. We have currently been using the default female voice, so I'll change it to the male voice on our next trip.

The point being that you should not buy any Garmin when Google Maps and WAZE will get you their faster and more accurately. Every Garmin (every GPS) is out-of-date on the release date and will always be 1-2 years behind what's really happening out there due to the delay between updates.

We had a new city by-pass open last week. Waze had it changed on the map within 2 days..Simple awesome.

There is one problem with Waze. It will not avoid low overhead clearance areas.

I've got a 770 and my thought was I needed way more things before taking off on our trip than the GPS so I waited to buy it until the week before we left. Didn't bother to learn to use it (IT's a GPS how hard can it be???) Well, I couldn't get it to navigate where I wanted to go (Well, my wife couldn't) so I said turn it off and I used Waze. About 3/4 mile from entrance on the road that the campground is on is a low overhead train bridge. Yea, I saw the sign AFTER I turned onto the road. Made a long day just a bit longer.

I still use Waze side by side with the GPS and sometimes follow it before the Garmin but I will still use both for times when I'm in an area that's questionable or off the major highways.

And that scenario is the whole point of having a dedicated RV/truck GPS

Ok, I have a question for all of you 770 experts. Why did mine route me off of I-25 in downtown Denver for a low clearance when Interstates are suppose to be much higher? It was set for 13'.
