Follow These Steps:
-Start the vehicle, and at the map screen use the navigation unit hard buttons as described:

-Press and hold the MAP/GUIDE, MENU, and CANCEL buttons for about 3 seconds. The display screen goes directly to the Select Diagnosis Items menu shown below.

• Self-Diagnosis Mode (runs the automatic diagnosis of the navigation system)
• Detail Information & Setting (allows you to manually diagnose the navigation system)

From the Select Diagnosis Items menu, select the Self-Diagnosis Mode. The screen changes to the System Links screen, and automatically begins running the self diagnostic. See the System Links section for more information.

Click ECU Info.
This screen looks for problems in the audio-navigation unit. When you initiate this diagnosis, the audio-navigation unit may freeze or delay up to a minute while the diagnosis runs.
NOTE: Do not try to end this diagnostic by pressing OK or Mem clear before it finishes, otherwise the system may reboot.

Your serial number will be listed there.

 

sweet thanks for the info!!!

n im not doggin on you but....y would you need the S/N to your navi system? i just wondering just in case if i run into a situation...

 

so you dont have to take out the audio/navi unit to get the serial number for your navi code.

 

Anyone tried this on the 2015 Fit EXL with navi? I need to find the radio serial soI can get the security codes for radio and navigation if I change the battery. Thanks
