The Garmin dezl 770LMTHD is Garmin’s annual truck GPS refresh in the 7″ screen market. The 7-inch pinch-to-zoom display operates similarly to what you would find on any smartphone. This GPS includes a lot of premium features including lifetime traffic, bluetooth and voice recognition. The traffic that’s available for this GPS includes the HD version which is a bit more complete and accurate versus the standard that was available with the predecessor which was the 760LMT. The GPS has features that are useful for truckers such as routes customized towards the weight of the vehicle, truck stops and other information (such as bridge heights). The GPS also integrates with your smartphone and you can log your hours of operation. When it comes to a GPS for truckers, this is a useful device.
We’ll review mounting options in a bit. Whenever we discuss a Garmin GPS with traffic, I like to drop a note about the cable. Don’t lose the cable. Your traffic subscription is tied to the actual cable. If you lose your cable, you will need to replace with a very expensive (about $60) traffic charger. A plain car charger will not provide you with traffic, you need to buy the HD traffic cable with traffic incorporated into it.
Now for the mounts. The dezl 770LMTHD is similar to the other dezl models before it using a ball and socket design. This cradle fits over a 17mm ball which is part of the mount. The dezl 770LMTHD shares the magnetic cradle with the older dezl 760LMT. I really like this cradle as it’s much faster to align the magnetic mount with the GPS. Easy and fast to insert and remove your GPS. The cradle is easily removed from the mount by simply pulling it off and pushing it on.
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). Garmin also includes 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 might not be legal. 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 mount. 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 dashboard disk as well.
If you would rather not put adhesive on your dash, you could use this cradle with Garmin’s highly regarded bean bag mount which we discussed in a prior article. This is great for an easy to install and remove mounting solution. When you’re done, just drop it in your glove box or under your seat.
As previously mentioned, the dezl 770LMTHD is a trucker’s GPS. A truck has an extremely long reach to the windshield and I find it surprising that Garmin does not provide an extra long mount. Fortunately the people at Arkon provide a nicely constructed extra long mount that will fit this line. The mount included a 17mm ball adapter that is made to fit the socket on the back of your magnetic cradle that came with the dezl. It extends from 14-18 inches and has a metal arm that withstands vibrations reasonably well.
I typically like to recommend some motorcycle options wherever possible. Unfortunately this dezl is very thick and the expandable cradles that I would normally recommend aren’t quite deep enough to fit the dezl 770LMTHD. While you can purchase a handlebar mount that will fit the back of the magnetic cradle, I simply don’t feel comfortable using that on a motorcycle so recommend not going that route. Therefore this might not be a suitable model for use on a motorcycle.
