Thanks for Replies Guys,
Update:
1. Confirming: all maps loaded from mapsource onto SD card
2. Confirming : No maps in any files on garmin unit internal memory
3. I tried this: removed all maps from SD card except Garmin NA 2011. Confirmed by looking in map set-up in unit. Then I sent a variety of CA TOPO 11 tiles to card. Zooming in, maps not observed, no change from before. Map shows as CA Topo 11 in Setup as enabled. Renaming on SD card has no effect.
4. CA Topo 11: Monterey (wn) San Jose (ws)" are typical map/tile names that show up in MapSource and on SD card and in Garmin map set-up. There are never any 8 digit numbers associated with any CA Topo 11 tiles. I have selected them all to double check. In contrast, Old CA Topo shows the 8 digit numbers for the tiles in all circumstances, and I can always see those maps..... hmmmmm. could this be the problem? Not sure
