Garmin RV 660LMT GPS Mounts

Garmin RV 660LMT GPS MountsGarmin must have wanted to market a GPS that was big, but not too big.  Hence, we bring you the Garmin RV 660LMT.  This is a GPS made for RV owners with features that are important to that specialty market.  This model includes free lifetime maps and a traffic subscription.  This 6″ screen model introduces some new display features to allow customization of the vehicle you see on the display.  This GPS carries forward options from the prior RV models including customized RV routing for the United States and Canada and includes America’s RV Parks & Services Directory.  The Garmin RV 660LMT includes Voice Commands, Bluetooth and Smartphone Link.

Keep in mind that the traffic subscription is tied into your car charger.  So don’t lose it.  If you do lose it, don’t try to replace it with a basic car charger because while it may power your device, the traffic will not work.  You will need to buy a Garmin GTM 60 HD Digital Traffic Receiver with a brand new subscription.  It’s sometimes easy to take your GPS and leave the charger, so please try to remember to not leave it behind.

On to the mount discussion.  The Garmin RV 660LMT mounting design is similar to the other mounts that Garmin has made available to the automotive market for more than ten years using a ball and socket design.  This cradle fits over a 17mm ball which is part of the mount.  The Garmin RV 660LMT leverages the same mount that many of the current Garmin 6″ screen car GPS models utilize.  The cradle is easily removed from the mount by simply pulling it off and pushing it on.  The back of the cradle has a 17mm socket which can be used with many other mount offerings.

The default mount that is provided with the GPS is the typical Garmin suction cup except the neck is a little longer than a smaller 5″ screen model.  This is the same mounting suction cup base that Garmin has used for roughly the past ten years (they changed the cradle, not the base mount).  If looking to replace this mount with the same model from Garmin, be sure that you don’t buy the one that’s made for the smaller screen GPS models as the suction cup model that comes with them will be too short and your GPS will potentially hit the windshield and not fit properly.  You need to buy the one that has the longer neck on the mount.

If your suction cup has failed, read our article on reviving it here.  If after reading the article, it’s still failing but the cradle is still good, replace it with a good quality mount like the Arkon Suction Cup Mount for Garmin GPS Devices.  This mount is in the photo that accompanies this article.  These Arkon mounts come with a 2-year warranty and these stick real well.  Like the Garmin mount, the Arkon brand comes with an adhesive disk for those that wish to use it on the dashboard.  This adhesive dash disk is especially useful if you are planning to drive in a state like California where windshield mounting may not be legal.

As already mentioned, this GPS is marketed to the RV crowd.  The windshield in a RV can be a far reach to the driver so a longer suction mount might be called for.  Fortunately the people at Arkon provide a nicely constructed Extra Long Suction Cup Mount for Garmin and TomTom GPS Devices that will fit this line.  The mount included a 17mm ball adapter that is made to fit the socket on the back of your power cradle.  It extends from 14-18 inches and has a metal arm that withstands vibrations reasonably well.

If you would prefer not to mount this GPS on the windshield, that’s ok, there are a lot of other mounts that permit alternative locations within your vehicle.  The dashboard is a very popular place to put your GPS.  For many years, the Garmin Bean Bag Dashboard Mount has been the answer to customers that prefer a different location.  It’s a heavy mount with a non skid bottom and has that 17mm ball built-in to fit the socket on the back of your cradle.  If you would like to read more on this mount, we did a detailed article on this mount awhile back.
