A:AnswerI recently purchased the Garmin 770 RV GPS. I've only used it once so far and it does warn about low bridges as well as weight restrictions. The only thing I've noticed so far is that it does not warn of tunnel restrictions. It has a lot of great features for finding gas, food and campgrounds as well.
A:AnswerNot sure what you mean by driver assist, but it does periodically ask if you want to take a break and suggests gas stations, restaurants, and rest stops.
A:AnswerNo, it would not! Because it is independently mount in the backside of the GOS and it doesn’t have anything with the electronic parts of the GPS
A:AnswerThe dēzl™ 770LMTHD is designed specifically for trucking and includes custom truck routing for the size and weight of the truck. This model also includes a Truck & Trailer Services Directory, plus points of interest (POIs) highly-rated by truckers.
A:AnswerIf your asking if it shows the elevation you are at then the answer is no. Sorry, when I think of an altimeter I think in relation to an airplane.
A:AnswerProbably not the best option, this model doesn’t include any truck specific routing. The Garmin dēzl™ series includes detailed maps for North America that also include truck-related restrictions – like bridge heights, sharp curves, weight limits, hazmat and more – and related information for most major roads and highways.
A:AnswerLive traffic information can be received through your compatible smartphone's data plan, and can be sent instantaneously to your Garmin automotive navigator through the free Smartphone Link app. This information allows your Garmin device to display and help you avoid slow traffic due to accidents, construction, or other obstacles.
