Error code c340 - Konica Minolta Magicolor 4690MF Multifunction Laser Printer

The C340 uses 12 volts.

According to the manual, the C340 uses SD and MMC cards, not SDHC cards.

Time to start using a card reader.

hold down the power button when you turn it on until the calabaration screen comes up and that might fix your problem

Try using a different website where you can download the maps for free. These should work. If they don't, you might need a software update from the same web site before getting more maps: www8.garmin.com/support/collection.jsp?product=010-00401-20

I had the same problem on a trip. Required two fixes and once I did this the unit worked fine.
1. Replace the fuse in the car adapter (reason it wasn't charging when I used it in the car).
2. See the users manual on page 31 regarding resetting your C340.

Make sure you are outside with a clear view of the sky. It will lock faster if you are not moving.

This should be available from Garmin. Check their website at www.garmin.com. Click on the C340. It may be available online.

Make sure that the camera has sufficient power when connecting and aslo try connecting the cam w/out the sdcard
