My SPIII won't read the memory card. The GPSR will locate sats and function on the base map but won't read from the card. The mapsource info downloaded to the card OK (i think) and all the software is installed, any ideas
Performed the mapsource update from garmins website to run the unlock wizard, are there any other updates
