I/ve loaded the latest speedcamera database via usb for the last 11/12 years. Recently though, the usb connection has been unusable, i.e. not showing up the Garmin as a drive on Mac or in Win10.
After reading a number of threads on here, is there any point looking for pre-boot mode (on the circuit boards) on my DNX7240BT when the system thinks it is the year 2002 ?

First check in the device settings that you have not switched it to MTP mode connection instead of MASS Storage.

If everything is fine, then it's a hardware problem, probably a damaged USB connector, or worse - a chip

Btw, it’s a pretty old device, and users have already complained that it juts fails ...

Thanks, read those threads along with numerous others. I've examined my unit and found the board very similar to one in this thread ; [Only registered and activated users can see links. ]
After attaching a wire to the switch, I rebuilt it and tried using Cure3 & Gupdate.gcd but the USB connection is still flaky. i.e. unable to see content or drag n drop.
