Golf maps 7.30 won't update

I've just updated my S70 to the latest software version 17.23. That downloaded and updated without issue over my WiFi network using the watch.  I noticed that there are Golf Course map updates version 17.30 to download.  I tried to update that but on each occasion they fail as they are nearly complete.  I do have a computer but it's so old and slow, that's why I never use it.  Anyone else had issues and does anyone have a solution without using my computer?
