Can't update maps on my Navman MY85XLT

I have a Navman MY85XLT that hasn't been used much since I got the Kakadu since it has a factory GPS with a larger screen. A couple of map updates have come out since I last updated my unit so I thought I may as well apply them. The trouble is the Navdesk software doesn't seem to be detecting the unit is connected to my PC even though the PC shows it as a drive letter, etc.

I am running Navdesk 7.50 and have tried uninstalling it and re-installing it but still no go. The original DVD is in my DVD drive, have also tried it without (pretty sure it has to be in though). I have the USB connection graphic showing on the Navman's screen.

Have I missed something?

Have also tried setting the Navdesk app to run in Win 7 compatibility mode since I run 64-bit Win 7 Ultimate, also tried turning on "run as administrator".

Not sure if I was imagining things before but the unit is not showing under my PCs drive list now but USB connection logo is displayed.

Are you using a short (about 8cm) USB lead? I found the longer ones don't detect with my MY80 GPS.

Yes I'm using the original Navman USB lead that came with the unit.

Since my last post I have run Windows Update, installed some updates but no specific Navman ones, and can now see the unit as a drive letter but not any files or folders. Also noticed the PC won't boot with the unit connected, have to wait till after it has booted up before connecting the cable. Still can't see anything other than the most basic options under Navdesk.

What's most annoying is that if I disconnect the unit and turn it on it keeps telling me a map update may be available. Tell me something I don't know!
