VOICE CONTROL DOES NOT WORK 

Diagnostic Test: Navi System Link and Functional Setup 

Before assuming that a voice complaint is hardware related, ensure that the voice control system is being 
operated correctly. 

z

Make sure you are on the correct screen when trying to issue a voice command. For instance, the 
command "Find the nearest Italian Restaurant" only works on a Map screen. (See the Navigation Owner's 
manual for a complete list of allowed voice commands for the information being displayed).  

z

Close the windows and sunroof  

z

Set the fan speed to low (1 of 2).  

z

Adjust the air flow from the air conditioning vents so that they do not blow against the microphone on the 
ceiling.  

z

Pause after pressing the TALK button, then give a voice command clearly in a natural speaking voice. If 
the system cannot recognize your command, speak louder.  

z

If the microphone picks up voices other than yours, the system may not interpret your voice commands 
correctly.  

z

If you speak a command with something in your mouth, the system may misunderstand your command. 

1. Go into the Diagnostic mode and use the "Mic Level" diagnostic under Functional Setup (see MIC 

LEVEL ) to check the operation of the TALK and BACK buttons. 

Are the TALK and BACK buttons operational? 

YES -Go to step 2. 

NO -Check for an open or short to ground on navigation unit connector B (14P) terminal No. 10 or 
a faulty voice control switch assembly. 

2. Use the "Mic Level" diagnostic under Functional Setup (see MIC LEVEL ) to check the operation 

of the microphone. 

Is the microphone operational?

NOTE:

z

Always check the connectors for poor connections or loose terminals.  

z

Before troubleshooting, write down the customer's radio station presets, 
and get the radio and navigation system anti-theft codes.  

z

After troubleshooting, enter the radio and navigation system anti-theft 
codes, and the radio station presets.
