Well as it turns out, I received the unit yesterday and am going to return it. It's just not....anywhere NEAR appropriate for aviation. You guys were right, I have to admit. My apologies for my behavior in this thread at one point (SoCal). It was kind of like I knew ahead of time what many of the responses would be geared towards (not using a GPS as a pupil of aviation). In fact, I think I am going to wait until after I get my PPL to get a full-blown aviation GPS. Thanks for all the solid advice, guys, and once again, my sincere apologies.
