DIAGNOSIS TIPS CONCERNING THE 
NAVIGATION FUNCTION

1. The precision of the GPS positioning is limited 

due to its operation principles. So, some of cus-
tomer reports do not mean that the system is 
defective.

Prior to troubleshooting, question your customer 
about how the navigation system is used and 
where he/she drives. If you determine that the 
system is OK, explain to your customer about 
how the system works and how the customer 
should operate it.

2. If the system is not OK, diagnose the system 

according to the trouble symptom chart.
