Screensize Oregon vs. Colorado in GPS technology and devices Posted August 3, 2008 I just got an Oregon 300 and want to get an Invisible Shield for it. By comparing the two on the Garmin website the display size seems to be the same. Zagg doesn't list an Oregon screen yet, so I was wondering if the Colorado screen protector would be the right size. I am guessing yes. Anyone put the Colorado invisible shield on the Oregon yet. g-o-cashers?
