OK - not positive where to post this, but if anyone has RECENTLY updated their Zumo maps, I could use some advice. As I recall, the last time I updated several years ago, I fought a bit with the space requirements on the unit (~1GB), but eventually, it fit. This time around, Garmin's site says that 13GB disc space is required for the NA maps. The Zumo has an SD card slot, so I can add one, but when updating, will the internal and SD space simply be used as needed, or do I manually need to route to those areas? I've read up on the Zumo forum and Advrider, but there are no recent posts that seem to clearly explain how to do this. Any advice is appreciated.
