Garmin Dezl 770LMT Screen Replacement

Turn the device screen down and using the screwdriver remove all eight screws from the back plate.

Place a nylon spudger in the seam between the front and back panel and carefully lift around the edge of the device.

Use the spudger to pry apart the screen from all around the device.

After you've removed the back cover, you will see a copper colored ribbon connected to a grey hinge.

Carefully remove the hinge from the cord using a spudger and the ribbon will come out.

Now you have the screen, which is enclosed by another cover. Remove the eight screws that hold it in place.

Once the screws have been taken out, use a spudger to carefully remove the cover. With this cover removed, the screen is now completely exposed.
