Safety Warning

Save User's Memory
If the HDD is good, transfer it to the new audio-navigation unit. If the HDD is NG, try this procedure to see if you can recover some information.
When replacing the audio-navigation unit, this function allows the dealer to transfer the client's personal data to the new audio-navigation unit. The transferred information includes their Setup settings, and personal addresses. The dealer inserts a USB memory device into the USB adapter, and then selects the Save User's Memory function. The two functions in this diagnostic screen are Export and Import. Export saves the client's data to the USB memory device, and Import moves the USB memory device files to the new audio-navigation unit.
1. Select Export button to move the client's data from the original audio-navigation unit to the USB memory. Select the YES icon on the Export User Data Confirmation screen. The process takes only a couple of seconds. The system stores.DAT files on the USB memory.
2. After replacing the new audio-navigation unit, allow the system to boot up. Insert the USB memory device into the USB adapter and enter the Save User's Memory in the navigation system diagnostic mode
3. Select Import button to move the two files stored by the Export process from the USB memory device to the new audio-navigation unit. Select the YES icon on the Import User Data Confirmation screen. When the transfer is finished (a few seconds) the system automatically reboots. After the system reboots, remove the USB memory device from the USB adapter.
