•  The device is not a toy. Never allow children to play with 
the device. 
•  Never touch the liquid that might leak from a broken liquid 
crystal display. Contact with this liquid could cause a skin 
rash. If the crystal display liquid should come into contact 
with the skin or clothing, wash it immediately with clean 
water. 
•  Never raise the sound volume level too high when using 
the device with earphones. An excessive sound volume 
level could cause damage to your hearing. 
Car mount precautions 
•  Some countries prohibit the mounting of any electronic 
device in any location on the vehicle dashboard. Be sure 
to check the local laws for applicable mounting before 
installing the car mount. 
•  Some newer vehicle models may have a heat reflective 
shield embedded in the windshield. This may in some cases 
obstruct the GPS signal reception. If you encounter this 
problem in the vehicle, you need to purchase an external 
GPS antenna. 
•  The heating and cooling cycle of a vehicle's interior will in 
some cases loosen the adhesion of the suction cup. Check 
the vacuum seal of the car mount for adequate adhesion 
each time you use the unit, and reinstall it if necessary. 
•  If the car mount has problems staying on, clean the plastic 
suction cup with alcohol, then reinstall. Moistening the 
suction cup may help adhesion in some cases. 
•  To avoid extreme temperature from damaging the car 
mount, remove the unit if the temperature inside your 
vehicle exceeds 70°C (160°F). 
•  The dip in humidity and temperature at night may loosen 
the adhesion of the suction cup. For this reason, as well as 
for security, it is recommended that you remove both the 
car mount kit and the NAV 350 when leaving your vehicle 
overnight.
