After plugging into the PC, the mode selection screen only appears for about **5 seconds**. Tap the **left-hand BLUE button** on the Navigator screen when the Navigator is first connected to the PC USB port. If you do not choose one of the three modes within 5 seconds, the Navigator defaults to the Sync Mode connection. When connected in Mass Storage mode, the Navigator will appear to your PC as if you had plugged in a pair of USB memory sticks. A drive letter will be assigned to each part of the Navigator's memory: - one for internal memory - one for the SD card **Mass Storage mode is used when connecting the HN5i to your PC for updates using the Naviextras Toolbox software** -
