I'm wondering if something similar happened to me. I had nhtopo11 and a few other GPSFileDepot maps installed in basecamp. I grabbed the OSM for Northeast and installed it. Now basecamp does not see any of my maps even after I removed OSM map. I'm going to try the JaVaWa software and see if it finds any errors. Everything was fine until I installed that map. Thanks for posting your info.
So it appears that auto was on. I set it to daytime. It looks much better. The background is tan not green like I'm used to but still much better than it was. Marine was off. I'm thinking this Oregon 600 will not display the green map background oh well I can still work with it as is. Thank you all for your help.
Hi all, I'm new to the site, great site by the way. I just got a Garmin Oregon 600 and have loaded the NHtopo11 map into it. No matter what I do the background of the topo is like a dark blue instead of the light green background that I am used to seeing in my etrex. I have attached a picture of the topo11 from my Oregon 600 and also the sample picture from GPSFileDepot site for the NHtopo map. Has anyone seen this before and any way for me to fix it? Thank you for any help and suggestions.
