Introduction

A step-by-step guide to removing the outer case of the Garmin Nuvi 680.

    • 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

  2. LJuoqmXTZBYifRs2
    • Remove the antenna cover.

    • Set the removed cover aside carefully.

    • 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.

    • 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.

  5. CpDWG2jDZmaVaVLL
    • 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.

    • 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.

Conclusion

To reassemble your device, follow these instructions in reverse order.

This guide works for the Garmin Nuvi 660 and 670 as well.

Thomas Bauer -

great instructions thank you! most of it also works for the NUVI 350, this one has an extra screw that holds the circuit board, and the connectors are different. Fixed the on/off button that broke of the soldering tips by re-soldering and adding some support at the back of the switch so this can't happen again.
