Just checked and my software version is still v5.0 so maybe this is the cause, as pointed out this older version will not recognize maps larger than 2GB. My CN NT North America v2013.20 is ~1.8GB and CN NT 2012.1 is ~1.97GB, so they seem to be just bellow the limit.

Can anyone tell me the recommended/safest procedure to upgrade the device software to v7.6? I've heard horror stories about trying to upgrade at the Garmin site and the device being "bricked" if for example the process is interrupted for any reason, local electrical/Internet outage, slow connection, etc.

Thanks for all the replies so far.
