This is a known problem that Garmin is already working on resolving. The new 60/76C/CSx models have a modified USB interface protocol that doesn't work correctly with nRoute. There should be a new version of either nRoute or the 60/76'x' model firmware to resolve the issue. No availability date yet though.
Good news! update is available at garnin for the gpsmap60csx to version 2.60
suppose to fix nroute and some other issues.
I have just installed version 2.60 and indeed it does seem to be working with nroute!
I had emailed garmin the other day on this issue and they told me 'we are aware of the issue but
ca not provide a time frame when an update will be available" haha,seems we know before there own tech support!
anyway,go update to your hearts content...
