All right, seems alot of you have used various Garmin products so I'll ask some help on any experience with software for those GPS's. I'm eyeing a GPSmap 76s now, but I know I'll have to buy more maps. I'd like to use it for hiking and MT. biking, as well as motorcycle/car trips. So has anyone used their extra maps? The selection seems a little confusing ie., Metro Guide vs. points of intrest and US highways. Whats the difference? And the topo software, does it show trails and fireroads for my state in detail, or is it just general like their base map? Is there any other software compatible that is better or less expensive? I thought I saw MS streets and trips listed on another post, and National Geographic software also that looked nice in a local retailer. Sorry for all the questions , but no-one in the local chains has a clue it seems, and online explanations seem a little over my head I guess. Basically, I know some of you are using them, so I'd like to know if they're worth the money and how they work exactly. I imagine I somehow plot a course on my desktop, load it into the unit and then use it. What if I decide on another course, am I screwed unless I have a laptop? I know, I know, but a $100 for something I can't find any real info on and can't return once I open it seems a hassle, and if it is, I'll go back to using good old infantry land nav. Thanks.
