I bought an Oregon 450, against my husband's advice to buy the 450t. I thought I could do all the free map installs, etc. Well, I'm technologically challenged! I tried to use the 450 for geocaching, but it was not the greatest. I thought about returning it for the 450t, but then I thought I could just buy the $99 Southwest area map from Garmin. We use it for hiking and riding trailroads with our motorcycles. Any advice before I rip my hair out?
