I have been following this thread with interest and have successfully down loaded an OSM map that covers Antigua to Base Camp but have come across a problem getting it to work on my Zumo 550 when loaded on to an SD card. It will work fine when loaded to the Zumo memory. I have a Garman life time update subscription and the maps of Europe that I have loaded on an SD card work fine.
I have loaded them in to a file ‘garman’ on the SD card but nothing that I have tried so far has allowed the Zumo to recognize them. Any ideas appreciated.
Is there any way to transfer maps to and from the SD card to the Zumo without the use of a computer?
Is there a noticeable difference in speed when using maps on the SD card as apposed to the memory?
Is it possible to load OSM maps on to an Android tablet and access them with a program like Base Camp and then transfer routs to a Zumo?
If anybody is wondering why I need a GPS map of a 100sq mile island, I don’t, but as I live here it makes for a good test. The detail and accuracy of the OSM map is impressive.
