2 FEATURES
The CN-VM4270A DVD Mobile Navigation System
combining with latest NAVTECH´s MAP Disc has following
special features:
·
Detailed maps are used.
Selected destinations will be displayed for easy viewing.
·
Desired places can be registered.
A destination can be set whenever you like from among
the desired places and facilities registered.
3 MAINTENANCE
Your products is designed and manufactured to ensure a
minimum of maintenance. Use a soft cloth for routine exterior
cleaning. Never use benzine, thinner or other solvent.
4 DVD DECK ALIGNMENT
DVD Deck Block
This model has no servo alignment points because
microcomputer controls the servo circuit.
