Thread: Garmin StreetPilot 2610

It seems your problem is not with MS or BC or USB drivers, it's with the device itself or how Windows is treating it. StreetPilot 2610 does not connect in Mass Storage Mode in Windows, so i don't know why your BMW unit is being recognised as such and given a drive letter [E:] by Windows. It should not be visible as a removable device at all. It would normally be seen by MS & BC directly without it appearing in Windows Explorer/Computer or Device Manager/Disk Management.

I suppose you have already tried cold rebooting your PC, then reconnecting the GPS after it's powered up, and finally opening MS or BC.

This is how SP 2610 should appear, only shown in Devices & Printers without a letter:



GARMIN (H:) showing in Disk Management above is not the SP, it's a 4GB logical drive on my main HDD.

I have had no direct dealings with the BMW II navigators, but i believe that you are correct when you say the hardware is the same as SP 2610. There are slight differences in the firmware only afaik.

OK, i think i understand now. I misunderstood before because you had the card 'E' in the 'Safely Remove Hardware and Eject Media' pop-up showing in your first screenshot in Post #11. I assumed you'd done that intentionally. My mistake. However, I'm unsure why you have drawn a question mark in your latest screenshot for Win 7 Disk Management. If you are thinking that the unit should be displayed there in some way, that's not the case with these older nav units. The modern nuvi-type units do show there when connected in Mass Storage Mode, but 26x0 SP era units do not show nor do they have a drive letter allocated.

So, in precis - In Win 7 on another PC you can see the unit in 'Devices and Printers' correctly and it's recognised by BaseCamp with no problems. But in Win 8.1 you get the yellow triangle error and it's not recognised by BC.

I guess a picture is worth a thousand words and i realise that English is not your first language. In 8.1 Devices and Printers, and then C:/Windows, please follow this:



You should have both gmngen.sys and gmnusb.sys shown under 'Driver File Details'. If either or both are not shown then reload the current Garmin USB driver version 3.2.1.0. If both files are shown, then proceed to C:/Windows/System32/drivers. Locate the 2 files, and check that the required permissions are allowed for 'All Application Packages' for both of those files.
