I went looking at Fry's for a mapping software and bought this before looking online at reviews. I'm now stuck with a bazillion (ok, just 17) CDs and a product that takes minutes to load once you initiallize the program. I still can't figure out how to access any info on Hawaii or Alaska and I'm waiting each time an average of four days before "tech support" haha will write me back.

Don't buy this.

I received this as a gift and what a dissapointment. Magellan has a topo product (mapsend) that works well with all gps's. All in one CD. It doesn't use images for the topo, just a simple map format. This product however is very inferior and offers even less detail than the other topos plus it can't be downloaded to gps's. I am very dissapointed and I continue to try to find out what features it excels at given that it has 17 CD's. It has to do something with all of that right? As it turns out it is just a poor design that was used as an attempt to get that paper topo map feel. It seems they just scanned in all the topo maps for the US, no wonder it took so many cd's. Don't waste your money.

I received this as a Christmas gift and had to return. Was not compatible and couldn't load on a brand new computer. Software gave no ability to customize the installation. No help from the Nat. Geo website support. Went thru the entire install and at last bar.....sorry, disc couldn't finalize hit finish to continue and it kicks you out completely to start over again.

From the other poor reviews, I'd have to say I'm glad I returned.

Bought this at the Apple Store on an impulse and boy am I sorry. Ditto what the other reviewers said plus there's no hardcopy documentation and what is on the .pdf help file is laughable. Here's another thing, on the USGS 1:100K level, the maps consistently DO NOT line up and are often cut off. C'mon guys, how hard is it to scan in a map and line them up? If you're happy with 1:100K or 1:500K,or need a fine quality state/county map or even a road map with elevation info, then this might be for you, but don't expect to go hiking with it.

Too many CD's that must be swapped in/out. Also misleading claims about down loading ability to GPS devices etc. I would not recommend this for the serious user.
