Locking Your nüvi
Garmin Lock ™ is a theft-deterrent system
that locks your nüvi. Each time you turn
on the nüvi, enter the PIN or drive to the
security location.
1. Touch Tools > Settings >
Security .
2. Touch the button below Garmin
Lock .
3. Enter a 4-digit PIN and drive to a
security location.
What is a Security Location?
Select a location you return to often,
such as your home, for your security
location. If the nüvi has satellite signals
and you are at the security location, you
do not need to enter the PIN.
noTe: If you forget your PIN
and your security location, you
must send your nüvi to Garmin
to get it unlocked. You must also
send a valid product registration
or proof of purchase.
