Summary: Seller was very rsponsive when I had an unrelated problem with my eTrex20 that initially prevented me from loading and using these maps. Went FAR above and beyond in helping me to solve the problem,
Summary: OSM maps are absolutely free and work perfectly with this unit. This is a great device and a big improvement over the previous model with much increased memory capacity. Battery life is still excellent.
Map was kind of old version but it is good enough to use for bike tour

Summary: I have purchased for Garmin etrex30. When I got first card it was not working properly. I am gonna use for S. Korea bike tour but no map for Korea map. When I e-mail to Mr. john , he responded right away. Unfortunately second didn't work. Third time finally its working.
Summary: I havent had a chance yet to do any major hiking with it but it did show me the way back to my starting point. The directions are not as clear on how to use it as I would like but i am sure over time it will really come in handy. I like tge small size and the cute little joystick.
