Entertainment Systems Limited GPS reception System performance may be adversely affected if GPS reception is interrupted or interference occurs over a distance of several miles. The following are possible causes for GPS reception being interrupted. If the vehicle is: • in multi-story parking garages • in tunnels and under bridges • inside or in between buildings • by forests or tree-lined avenues • in heavy rain showers and thunderstorms • in valleys and in mountainous regions • roads under cliffs Ensure that you do not have any metal objects on the rear parcel shelf and that if your windows are tinted, they use non-metal tinting instead of metal oxide tinting. Both of these factors can also interrupt GPS reception. Cleaning the display Do not spray cleaning fluid directly onto the unit. Instead, spray onto a soft cloth and gently wipe the unit. Only recommended products should be used. Do not clean any part of the system with benzene, paint thinner or any other solvent. Do not spill liquids of any kind onto the unit. Loading the map DVD • Your navigation DVD unit is either located: in the front lower center stack area by the passenger's feet (access door), in the trunk, or in the jack compartment. • Ensure that the vehicle ignition is ON. • If a DVD is already loaded in the Navigation unit, push the eject button. • Load the DVD with the printed side up. Do not allow moisture or foreign objects to enter the slot. The navigation system utilizes a database stored in a special format on a DVD. It is recommended always to use the latest update of this map DVD. 70
