I have a BMW Nav V which I believe is the top of the range Nuvi. In short, my PC won't connect.
I have a new Windows 8.1 laptop, I have deleted both the Express and Drivers and have totally reinstalled both. I have restarted the pc many times but to no avail. I have been through the Garmin FAQs but nothing there helps. I am using the original Garmin cable and here's the rub - it works perfectly on my wife's Windows 8 laptop and I have been able to update the firmware using that machine therefore the Nav V is also up to date.
I also disabled the firewall. The device does not show up as a storage device in the file explorer.
I think that's it!
Having done all this and seeing it work perfectly well on another machine, I am totally stumped!
Any tips gratefully received!
