Audio-Navigation Unit and HDD Service Precautions

WARNING: This page does not describe the selected car, but rather 7 other vehicles, including the 2017 Honda Odyssey, 2016 Honda Odyssey, 2015 Honda Odyssey, 2014 Honda Odyssey, and 2013 Honda Odyssey. However, it is still accessible from the selected car via links, so may be relevant.

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

When you get a replacement audio-navigation unit, the unit arrives able to mate one time to a HDD. When you connect the audio-navigation unit to the HDD 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 HDD that is already mated to another audio-navigation unit. It does accept a new HDD.

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

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

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

If you need to replace the HDD, there is no way to transfer customer data, music, or pictures to a new HDD. Explain to your customer that their music and personal information is not transferable. The navigation system has the save users memory function available, but Honda does not recommend using it. If the HDD 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 HDD, you can try to back-up the navigation data (if possible) and transfer it to the new HDD. See SAVE USERS MEMORY . The save users memory function only copies customer settings and phone information. There is no way to copy or transfer music and photographs that are saved on the HDD to a new HDD. Explain to your customer that this information is not transferable and will be lost.

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 transmission DTCs and freeze frame date (which are lost when the PCM loses power).
After reconnecting the battery, you have to wait to get the initial signal from the satellite. It will take from
to 45 minutes.
Adjust the setup clock settings (time zone and daylight savings) in the navigation system.
Enter the customer's audio presets.
Install any discs that were removed.
