NOTE:
 Check the vehicle battery condition first.
 Make sure the vehicle is parked outside and away from buildings.
 Refer to GPS Information (see page 23-142) for realtime satellite reception display.
 Check for window tinting above the GPS antenna and any non-OEM accessories mounted near the
navigation unit or GPS antenna.
1. Check for metallic window tint on the windshield and electronic aftermarket accessories (possibly
hidden) mounted near the GPS antenna or the
navigation unit.
Remove tint or the accessories, and
recheck.
Go to step 2.
2. Go into the Diagnostic Menu, and use the Navi System Link test (see page 23-136) to check the
GPS antenna.
Use the Navi ECU test under Unit Check
(see page 23-139) to check for a kinked, crushed, or
disconnected GPS antenna wire. If necessary, try a
known-good GPS antenna. If icon is still red,
replace the navigation unit (see page 23-155).
Check that nothing is blocking the GPS
antenna located behind the gauge assembly, and
recheck. Substitute a known-good navigation unit,
and recheck. NOTE:
 Check the vehicle battery condition first.
 Make sure that the correct DVD color and version are installed.
 Check any official Honda service website for more service information about the navigation system.
 Check that the volume setting and voice feedback are turned ON.
 Check the connectors for poor connection or loose terminals.
 Before troubleshooting, make sure you have the navigation system 4-digit anti-theft code.
 After troubleshooting, enter the navigation system anti-theft code.
1. Press the display unit SET-UP button.
2. Check the volume setting for the navigation system.
Set the volume to an audible level.
Go to step 3.
3. Check the radio operation.
Go to step 4.
