Introduction

A step-by-step guide to replacing the battery in the Garmin Nuvi 680.

Tools

Step 1

Locate the antenna on the back of the device and gently flip it open to reveal the screws underneath.
Remove the two 4.42 mm screws in the top-left and top-right corners of the antenna cover using a T5 Torx screwdriver

Step 2

Remove the antenna cover.
Set the removed cover aside carefully.

Step 3

The yellow wire is connected to the motherboard. Do not disconnect it until you finish opening the device.
Locate the green antenna circuit board in the middle of the case.
Gently use 1 or 2 fingers to grab and pull the antenna circuit board out of the middle of the case.

Step 4

Insert the pointed end of a spudger into the leftmost slit at the top of the antenna case, where you previously removed the circuit board
Once the spudger is inserted into the leftmost end of the slit at the top of the antenna case, slide it to the rightmost side of the slit.
Slide the antenna case out slowly or you may lose the antenna's spring. The spring is inside the black plastic that holds the antenna case to the device.
Slide the antenna case out of the device.
Reinstallation tip: first reassemble the antenna casing (place antenna back into its plastic cover), and then re-insert the entire assembly back into the GPS body.

Step 5

Identify the antenna assembly, which is now exposed after removing the antenna cover.
The two screws are positioned at the top-left and top-right corners of the antenna assembly
Use a T5 Torx screwdriver to remove the 10.82 mm screws from the top-left and top-right corners of the antenna assembly.

Step 6

Locate the top side of the outer case.
Using your iFixit Opening Tool, gently insert a flat end of the tool into the slit of the top cover.
Use the Opening Tool and your hands to pull apart the front and back of the device. Grip the top and bottom sides with your hand while inserting the tool into the slit to gently separate the two halves
One end of the front and back of the outer case are still connected by ribbon cables.

Step 7

Use a spudger to disconnect the yellow antenna wire from the ZIF connector by opening the brown latch holding the wire in place.
Remove the antenna.

The antenna ribbon cable has a latch that must be lifted first. It's a light muddy brown color. It flips up and away in the opposite direction of the ribbon cable.

Step 8

Do not remove the ribbon cables without lifting the latch or the cable will be damaged.
Lift the latches on the ribbon cable connectors. All the ribbon cables may have latches. The right most latch may have a latch that flips in the opposite direction from the others.
Gently pull the ribbon cables out of their connectors. They should slide out easily.
Do not separate the two halves of the device yet or the on/off cable may be severed.

Step 9

Gently pull the cable for the on/off button straight up to remove it.
The two halves of the device may now be separated.

Step 10

Use a PH1-sized Philips screwdriver to remove the two screws that located towards the center of the motherboard.
These screws are 6.88 mm long.

Step 11

Carefully separate the motherboard from the outer case or the speaker and battery cables may be damaged.
Use a spudger to lift the edge of the motherboard.
Insert it at the bottom and use it as leverage to slowly release the motherboard from the case.
