To carry out the steps in this Instructable you will need the items in the picture above;

Apologies for the poor quality of many of the photos in this instructable sadly I was photographing as I went along and not checking the focus of the shots! Hopefully you can get the idea though.
Step 1: Remove the Receiver Unit From the Adaptor
Remove the GPS Receiver Unit from the Adaptor.
Both these photos but particularly the second one shows that the USB connector is at an odd angle due to the break inside the unit.
Step 2: Remove Case Securing Screws
Remove the case securing screws which are concealed beneath the label. I located them by feeling for the screw holes through the label and the pushing the screwdriver tip through the label to release and remove the screws.
Step 3: Remove the Case Cover.
Remove the Case Half to reveal the Printed Circuit Board.
Step 4: Unsolder the Broken Connector
Unsolder any remaining connections using the soldering iron and desoldering pump.
Also remove any excess old solder and broken contact legs from the contact pads on the PCB.
Step 5: Trim Securing Legs
Trim away un-needed metal securing tabs/legs from the new USB Connector using the Side Cutters.
Step 6: Solder New USB Connector
Solder the new USB Connector in place.
Step 7: Reassemble and Test
Reassemble the case using the screws removed earlier and the screwdriver.
Re-connect the Receiver unit to the Adaptor.
VOILA! Your Repair is Complete.
Now plug it in and test it.
