Very old Garmin devices which don't connect to a computer in Mass Storage Mode will automatically connect in "Garmin Mode" when USB drivers are loaded to the computer: [Only registered and activated users can see links. ].

For modern devices (those with a visible file system), G7ToWin is only usable in preboot mode: [Only registered and activated users can see links. ] and again the USB drivers must be loaded to the computer. If you don't access the unit quickly on connecting to the computer, it will exit preboot to the white calibration screen. Times do vary depending on unit series. Some units have a very brief window of opportunity, for example 7xx remains in preboot only for about 10 seconds and recent devices can be even shorter. So open G7ToWin before you put the unit into preboot mode. After you've configured it as below in the Options Setup (File>Configuration), leave the GUI visible on your desktop with 'GPS' selected ready to click 'Get GPS ID'.

Check 'USB' for 'COM Port' to use with usb-capable units, then click 'OK':


(thanks Alexander for the screen )

Put your unit into preboot mode and in GPS menu quickly click on Get GPS ID;

If you get an error screen ignore it and just click 'OK'.

Some units will be shown as a three-figure number, but in other locations such as detailed below a leading zero will be added to make a four-figure number, e.g. 0851 is the same HWID unit as 851.

OR, alternative ways to see HWID:

1. If your 'bricked' modern device was previously backed up check in its Garmin folder for the file GarminDevice.xml. Open it in a web browser or text reader like Notepad to see "<PartNumber>006-Bxxxx-00</PartNumber>" near start. Four-numeral 'xxxx' is your unit's HWID.

2. If your MSM unit isn't 'bricked', hold battery symbol on main screen for several seconds to reach a hidden menu, then press 'Next'/lower RH corner until you see 'Version Information' screen, then press 'Start Test' > 'More' to see 'Inventory' screen. Look for same 'Bxxx-00' in second entry of top 3 lines. However, even though old devices without MSM may show a similar hidden menu by holding the 'time' instead of the battery symbol, pressing next might not show a 'Version Information' page to disclose the HWID.
