Before you begin Read this website's Legal Guidelines and make sure you understand the risks of this repair. Place your Garmin Nuvi 660 on a clean flat and soft surface, such as a rubber mat or a piece of soft cloth and get the required opening tools
		Step 1 Open the GPS antenna.
		Step 2 Remove the two Torx T5 screws at the top of the antenna cover.
		Step 3 The goal is to reach the two screws next to the antenna hinges, but access to them is obstructed by the antenna. So the antenna needs to be removed first. First of all remove the antenna's backcover using a plastic opening tool. Just insert the opening tool in the seam on the side of the garmin antenna.
		Step 4 This is what it looks like when the cover is removed.
		Step 5 Use the edge of the small flathead screwdriver to push the black plastic cylinder that is the right antenna hinge toward the center of the antenna.
		Step 6 If you pull the antenna upward as you are pushing the cylinder inward, the right hinge will become dislodged.
		Step 7 The spring will push the cylinder out abruptly as soon as it becomes released, be careful not to lose it.
		Step 8 Now you have access to the two screws under the garmin antenna. Remove them using a Torx T4 screwdriver.
		Step 9 Use the opening tool to pry apart the front and back of the Garmin Nuvi housing.
		Step 10 Slide the opening tool toward the edge of the casing.
		Step 11 Slide it around the edge toward the headphone jack.
		Step 12 You should now be able to separate front and back.
		Step 13 The front containing the Garmin Nuvi 660 screen should now fold open as shown in the image.
		Step 14 Use the opening tool to carefully release the screen connector latch and the touch screen connector latch.
		Step 15 Finally release the backlight connector latch and remove all ribbon cables. You should now be able to separate the front from the GPS body.
		Step 16 You have successfully removed the screen of your Garmin Nuvi 660, for reassembly follow the steps in reverse order, using the new garmin replacement screen.
