  • Use a spudger to disconnect the yellow antenna wire from the ZIF connector on the back of the motherboard.

  • 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.

  • 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.

Great instructions, thank you

I was able to fix my GPS which I thought was headed for the recyclers.

Saved me from purchasing a replacement.
