My only complaint about the micro SD cards on the Garmin HCX Vista is that it only allows you to hold 2 gig of data or 2011 maps whichever comes first. I wish I could put a 16 gig card in and be done with it, so unfortunately I have to carry a small container with it for my maps. It is unique to me and may not apply to you but the maps I carry have topos,road and marine maps of most of the world and are quite a few micro SD cards. I wish Garmin would lift the restrictions of map sizes on the newer GPS. My goal is to have a AA powered GPS with maps of the entire world for my traveling. I'm slowly getting there....

Note: I have yet to find a better GPS for my needs than the Garmin Vista HCX but I'm always looking.

Advantages:
1. Small (pocket size)
2. 2-AA batteries (universal batteries with a long long run time)
3. Will give routing directions in street mode
4. waterproof
5. Can load topos,road and marine maps for many scenarios
6. Can run 100% (with no batteries in the unit) off a 40 watt portable solar cell
7. Highly sensitive GPS chipset that can be used under heavy canopy
8. In the event of a military satellite failure the maps are still usable like paper maps are and with solar capability a loss of the electrical grid system isn't an issue for recharging batteries or what have you.
9. Durable and reliable
