The Garmin mini usb port seems to be designed to break easily forcing you to buy a new GPS. This is how to bypass a broken usb port on the back of garmin GPS receivers. It will leave you with a GPS which works with the car adapter only.

The battery must be removed for safety since the yellow wire which sends a safety signal to the charging electronics about the battery heat levels will be bypassed. We will be powering the unit directly from the Garmin Car Charger (others may not work since Garmin has special circuitry in its chargers).

# using a mini torx screwdriver, remove all the screws and seperate the front and back of the case. # if the usb conector is still on the circuit board, carefully twist it off and discard # cut the car charger cable a few cm from the usb connector and strip the two wires back 0.5 cm.the middle wire is positive, the outer mesh sheath, negative.
