ISSUE
Some 2003-2005 Aviator and 2003-2006 Lincoln LS, Navigator and Town Car vehicles equipped with a navigation system, may not zoom closer than a 16 mile scale (32 Km) when detailed map data is available. This may be due to the software within the navigation unit.
ACTION
It may be necessary to update the navigation system software to v05.10. Refer to the following Service Procedure.
SERVICE PROCEDURE

1. Place the ignition switch in the run position and leave in this position throughout this entire procedure.
