Honda Map Update USB Not Detected by Garmin Express on a Windows Computer

USB communication issues can prevent your USB drive from being detected by the Garmin Express™ software.

Before starting the map update process, visit https://honda.garmin.com/honda for instructions on preparing your USB flash drive for the map update process. 

Using the Same USB Flash Drive for the Honda Map Update / Formatting the USB Flash Drive

When doing a Honda map update you may use the same USB flash drive that was used for a previous map update.  Prior to using the flash drive for the new update however, you will want to completely format the drive. 
See  Formatting a USB Drive for a Honda Navigation System
Once the flash drive has been formatted, you will want to follow the full update process found at https://honda.garmin.com/honda/. 

Ensure that Windows Recognizes the USB Drive

2. Press the Windows Key ()+ E

USB Drive Does not Display as a Drive in Windows

Try the steps below if the USB drive does not appear as a drive in Windows or appears as an "unknown device" in the Windows Device Manager. 

Ensure the USB port is Working Properly:

  • Try a different USB port on your computer and/or test the USB port with a different USB device
