I've got now 3 reports in - that with my maps the memory full bug is back again (remember around 3 years ago - when the more mkgmap maps (or non NT garmin City Navigator) with index you sent to your device - the more often/likely it would appear.
Well - it seems some mkgmap change is causing it again. So far I got reports from Montana 600 and Oregon 300 users - all on newest firmware.
Anyone else having probs - getting feedback? Any idea what change in mkgmap caused it? (seems garmin did not really fix it correctly but just worked around it with their firmwares).
