I have bought a City Navigator® Southeast Asia NT  downloadable map.  When I'm  trying to download and install it using myGarmin/myMaps I see a button "add to device", then I see:
City Navigator® Southeast Asia NT (605MB) will be associated with the device below. Each download can only be associated with one device. nüvi 3597 -   (325 MB available) Insufficient Space Software updated needed
I  choose  download  to sd card, the system starts to work and sends  software to device. 
 Next  message:  Software upgrade complete. Restart device.
1.Disconnect your device from your computer and allow it to restart itself.
2.When your device finishes restarting, turn it off.
3.Connect your device to the computer again.
4.Wait 30 seconds.
5.Click Continue.
Done what it asks - nothing  happens.  No self restart. No update. Cant start  downloading the map. 
When I try do connect  the  device again it  all goes round but  never  actually updates  the  software.  
Tried Garmin  Express  app,  Webupdate  both of them show  software up  to date.  Also tried to  clean up the space and choose internal memory instead of sd card. Tried different browsers,  OS, checked firewall/antivirus. Still all the same problem. The  device itself works ok -  no failures or messages.
Will  be thankful  for any  help and advice.  
Regards,  Alex.
