Audio-Navigation Unit and SD Module Service Precautions

Contrary to previous generations of DVD navigation systems, the audio-navigation unit and the SD module cannot be substituted separately for testing purposes. You can substitute a combined audio-navigation unit and SD module with a known-good combined audio-navigation unit and SD module. When the audio-navigation unit and SD module are connected to a vehicle, and powered up for the first time, the audio-navigation unit and SD module go through a mating process where the SD module writes the audio-navigation unit's serial number to its memory. The audio-navigation unit and SD module are available separately.

When you get a replacement audio-navigation unit, the unit arrives able to mate one time to a SD module. When you connect the audio-navigation unit to the SD module and power it up for the first time, the two components are mated. Once the audio-navigation unit is mated, it does not accept an SD module that is already mated to another audio-navigation unit. It does accept a new SD module.

The SD module is removable from the audio-navigation unit. If the audio-navigation unit is replaced, install the original SD module into the new audio-navigation unit. When you transfer the SD module, all the customer's settings are transferred.

The SD module is able to mate more than once, allowing you to transfer the SD module with the customer's information to a new audio-navigation unit. The SD module must mate to a new audio-navigation unit. It cannot mate to an audio-navigation unit that has been mated to another SD module.

A new audio-navigation unit is defined as a unit that has not been mated to an SD module. A new unit may be new or remanufactured.

If you need to replace the SD module because it has failed, there is no way to transfer customer data to a new SD module. Explain to your customer that their personal information is not transferable. The navigation system has the Save Users Memory function available, but Honda does not recommend using it. If the SD module is OK, install it in the new audio-navigation unit, and it will automatically transfer all the customer's information and settings.

If you need to replace the SD module, you can try to back-up the navigation data (if possible) and transfer it to the new SD module. See Save Users Memory. The Save Users Memory function only copies customer settings and phone information.

• When the battery is disconnected, the internal GPS clock resets to 0:00. The clock resets to the correct time after the system finishes GPS initialization.
• Before disconnecting the battery, obtain any PGM-FI or A/T DTCs and freeze frame data (which are lost when the ECM/PCM loses power).
• After reconnecting the battery, you have to wait to get the initial signal from the satellite. It will take from 10 to 45 minutes.
• Adjust the setup clock settings (time zone and daylight savings) in the navigation system.
