How to Open Lock the memory card through the reader
There is a Lock switch on the left side of the SD card. Make sure the Lock switch is slid up (unlock position). You will not be able to modify or delete the contents on the memory card if it is locked.
SOLUTION 2 - Toggle the lock switch.
If the lock switch is not on lock:
1. Slide the switch up and down. Repeat this 3 times.
2. Let it stay on the Lock position for 30 seconds.
3. Slide the switch up to unlock the card.
4. Try to transfer files into the device.
For non-SD cards: Format the card
The data on the memory card may be corrupted. Format the card under Disk Management and then try to transfer files to the device once more.
WARNING: Formatting will delete all the files in the device. Backup all your data before formatting.
SS1122, I also have a 276C, as far as I know you can't access the Data card memory directly like you can with a SD card, all you can do is to transfer Maps to the unit (or your card reader) through Mapsource.
When you connect the data card either via your card reader, or connecting the whole unit via USB cable to the PC, it doesnt come up as a seperate drive(in My Computer) as, say, a SD or other memory card would.
You should have no problems transferring any compatible chart or map to the unit through mapsource though. I did have a problem with my Data card reader, but no problems when the unit(+data card) connected directly to the PC via USB, Mapsource recognised it, so I'm not sure why you cant send maps to the unit via mapsource. Have you tried using a differant version of mapsource?
You will need the lastest firmware update on your 276C (276 firmware version 5.40) to work properly with the 512mb cards, but any version should work if your card is only 64mb. It may be worth updating the firmware anyway, just make sure the battery is fully charged on both the 276 and your laptop as a power out during update will zap the unit.
The 276C is a fairly dated(but still excellent) unit, so check compatibility with newer mapping/charts.
Used the mapsource program, but refuses to withdraw the map Is there a program pulls the map
What do you want to do? Delete map or read map from card?
Mapsource will overwrite your map when sending a new one. You don't have to delete it.
Maybe Sendmap can delete your map.
Maybe gpsdaemon can read your map.
