Avoiding Theft
• To avoid theft, remove the c550 and
mount from sight when not in use.
Remove the mark on the windshield
left by the suction cup.
• Do not keep your unit in the glove
compartment; thieves know where to
look.
• Register your product at www
.garmin.com/registration. This may
help if your unit is stolen.
• Use the Garmin Lock
™
feature. See
page 6.
Changing the Fuse
An AGC/3AG 2-Amp, high-breaking
capacity, 1500 A-rated fuse is located
at the tip of the vehicle adapter.
Periodically, you may need to change
the fuse. Unscrew the black, round end
piece, and replace the fuse.
