Contour lines not showing on Montana 600

[timgreggs]

I have a Montana 600 with city Navigator , Northwest topos and NW trails on a SD card. I used to see the contour lines when I was in my geocaching profile. For some reason I cannot see the contour lines anymore. I can only guess a software upgrade caused a change. I have tried disabling all maps except the Northwest topos and I still don't have any topo lines displayed. I have read in other forums about changing profiles to fitness and then back , which didn't help either. Not sure what else to try? Any help here would be appreciated.

I'm not a Montana owner, but what can you see?  Also do you have your detail set to High, or Higher/

Try the recreational profile.

I have it on most detail and I tried the recreation profile, still no contour lines. Should I do a restore to factory defaults or a reset?

That's pretty strange. I have a Montana 600 and have never seen this happen. You could try doing a reset. I would do a full backup of all data on the Montana first, just in case though.
