Mounts for the Garmin RV 770 LMT-S GPS

Arkon GPSCM117 fits the Garmin RV 770 LMT-SLooks like Garmin is sticking with their specialty GPS line for RVs.  The Garmin RV 770 LMT-S is the second iteration of their RV line.

The Garmin RV 770 LMT-S is made for RV owners with features that are important to an RV owner.  This model includes free lifetime maps and a traffic subscription.  A big 7″ screen on this GPS is the largest made by Garmin for the automotive market.  Customized RV routing for the United States and Canada is included along with a directory of America’s RV Parks & Services.  The Garmin RV 770 LMT-S has Voice Commands, Bluetooth and Smartphone Link which along with a smartphone app will save the location of where your RV is parked.  Integrated Wi-Fi makes taking advantage of your live map subscription easy to update.

So let’s discuss the mounts.  The Garmin RV 770 LMT-S continues the typical ball and socket design for their mount.  Unlike last year’s model, they have moved the Garmin RV 770 LMT-S to the mounting cradle common to the Garmin Drive GPS.  Using a round adapter that snaps onto the back of the GPS, it’s easy to attach and remove it.  The back of that cradle has the 17mm socket common to all Garmin automotive GPS devices.

The default mount that is provided with the Garmin RV 770 LMT-S is the typical suction cup pedestal except the neck is a little longer than smaller GPS models.

If your suction cup has failed, read our article on reviving it here.  If after taking the plan outlined in the article, it’s still failing but the cradle is good, replace it with a good quality mount like the Arkon Suction Cup Mount for a Garmin GPS.  This mount has a longer neck and an additional adjustment point to get a better angle.  These mounts come with a 2-year warranty.

As the model name implies, this GPS is marketed to the RV crowd.  The windshield in a RV is often a far reach so a longer suction mount might be beneficial.  Consider the  Arkon Extension Windshield Mount for Garmin and TomTom GPS.  The mount included a 17mm ball adapter that is made to fit the socket on the back of the Garmin RV 770 LMT-S adapter.  It extends from 14-18 inches and has a metal arm that withstands vibrations reasonably well.  This mount comes with a 2-year warranty.

You don’t have to mount the Garmin RV 770 LMT-S on the windshield.  There are many other mounts that support alternative locations within your vehicle.

The dashboard is a very popular place to put a GPS.  The Garmin Bean Bag Dashboard Mount continues to be a solution for customers that prefer a different location.  It’s a heavy mount with a non skid bottom and has that 17mm ball that fits the socket on the back of the Garmin RV 770 LMT-S adapter.  If you would like to read more on this mount, we did a detailed article on this awhile back.

The last option for consideration is the Garmin Air Vent Mount.  Before selecting this mount, ensure your air vents are sturdy enough to support the weight of this larger GPS.  While the mount will work on most vents, we suggest horizontal vent slats for the most secure grip.  If your RV’s vent slats run up and down (vertically), we suggest one of the other mounts discussed in this article.  Just be sure your vents are sturdy enough before deciding on this mounting option.

So there are some options for mounting a Garmin RV 770 LMT-S GPS.  Some are traditional suction cup mounts while a few use alternative locations.  The most important selection criteria is placing the GPS where it’s safe and comfortable for the driver.  Don’t cover up places that can block or limit your line of sight.  Place the GPS where it’s safest and most secure.
