Garmin Dezl 780 LMT-S 7" Truck GPS with Advanced Navigation Features

Kindle Customer: My other GPS is a Garmin so when I needed a commercial GPS I went with this one because it’s what I am familiar with. It works great for me and the large screen is a plus except...... The mount can’t handle the weight of the GPS so it’s always drops down with every bump in the road. Extremely poor design. I tried using silicone caulk on my mount but that was only a temporary fix since the silicone doesn’t stick to plastic. Finally decided on a permanent fix and glued it. No going back now. Garmin needed to test this on a bumpy road.

skcsammy: Excellent GPS, nice bug screen, easier to make route adjustments than the smaller ones for me. Routing is overall excellent, keeps me out of trouble with height and weight restrictions. I highly recommend. It has a loud speaker to here over the road and truck noises. My only complaint is the pivot on the dash mount is weak. It holds the GPS fine but it pivots downward after a lot of bumping around, I haven't found a way to tighten it up.

AverageAaron: The quality of the physical device regarding the Garmin Dezl 780 is absolutely outstanding.

It is rugged, heavy and indestructible in feel when comparing to ANY of the Rand McNally units.

It includes a rubber shell whereas Rand McNally does not.

The screen is clear, bright, high in resolution, responsive and smooth.

The magnetic mount has a good design and holds very tightly, but the weight of the unit does not help it to stay in position so I’ve learned to rest mine on the dash.

The routing is right on par with Rand McNally, but no GPS that I’ve encountered ever suggests the literal perfect route, this is where using Google Maps or an Atlas really helps you (the professional driver) navigate efficiently and make smart course changes.

The interface is slightly more complex then Rand McNally but once tinkered with for awhile, becomes no challenge.

The coloring of the map is easier and more clear on the eyes.

It has a multitude of changeable options or route stats that one might want to see. Time of arrival, drive time left, mile marker you’re closest too, savable routes, direction heading, altitude, etc.

Avi8tor: This unit looks and performs like new. You will need to update your maps and garmin is not compatible with chrome book. It has to be a windows or Mac computer. Also, the update can’t be done wirelessly via your phone like my Rand McNally could. This is my only complaint about the unit. Not a problem for the seller. Over all, I’m very happy with this purchase.

DanD: I purchased this refurbished unit because it was 30 percent off the price of a brand new unit. Amazon gives a 90 day, no questions asked, return policy, and it comes with a 1 year manufacturers warranty.
When the unit arrived I was very pleased with the condition. I could not tell that the unit was refurbished. I am using this unit in an RV, not a truck, but it really doesn’t matter. I love that I am able to reroute the trip with the click of a button, and pick my own roads if I desire. This unit is feature rich. It will even notify you of deer crossings!
I’ve only used it on 1 trip so far (650 miles), but am very pleased. The size of the display is outstanding. In fact, I may put this in the car for long trips when I’m not using the RV.
