I've had my 400C for a couple of months now. its been great, until today. Today I got a message that says, "memory full" It won't do anything now, can't turn it on. It won't allow me to plug it into the usb so that I might delete the offending files. I've read posts regarding this issue. there is advice on how to do a reset. That has not worked. I will contact garmin tomorrow. other than that, its my first handheld and it seems to do the job quite well.
