Is there anyway of clearing the internal memory to enable the entire european map to load without using a MicroSD card? For instance deleting unused languages etc? I prefer to use the SD card for music files only.
My apologies, the North and South splits show up on the Nav5. However I do not have "Advanced Options" - the available map options are either "change map" or "reinstall map". Reinstall map only does just that. Up to 2017.2 I had the option to install to both PC and device, but that now seems to have disappeared.

... so frustratin.... 10 day route through Germany, Switzerland, Italy and France to plan for July.... can't fcuking wait 

After waiting 7 hours for my wet-string internet to download the map, it was installed to my Garmin 590 only. THEN. GE gives me the option to install it to my computer. Cue another 7 hour wet-string epic download.As others have said, the option Tomcat describes at step 5 is no longer there.

What bright spark at Garmin decided this was a good ideaif it ain't broke, don't fix it!
As others have said, the map on the device is in two parts. It would appear that the only difference between North and South is the high detail level of information. The basic map is fully present in both.
