→ Charge the built-in battery.
→ Check that the unit is securely attached to the cradle (page 8).
The built-in battery cannot be charged. → Check that the POWER switch on the bottom right of the unit is in the ON position.
→ If the AC power adapter is being used, disconnect it from the outlet, then reconnect.
→The built-in lithium-ion battery can be charged at temperatures between 5 – 45 °C (41 – 113 °F). The battery may not be charged if the temperature inside the unit increases because of direct sunlight exposure, etc. This is not a malfunction.

→The optional External GPS Antenna VCA-41 may be required for a heated or heat reflective windscreen.
• There is an obstacle in front of the GPS aerial.
→ Install the unit where the signal is not interrupted by the body of the car, etc. For details on the unit installation, see "Installing location" on page 5.
• Signal may not be received if a window film is attached. In that case, use the optional External GPS Antenna VCA-41.
The car position on the map does not match the current road. The error margin of the signal from the GPS satellites is too large. A maximum error margin of a few hundred metres can exist.
