Excerpt: UPDATE: This unit is out of production. It connects with a serial cord, seems like Garmin is all USB now.I had to buy a Belkin serial/USB adapter to continue programmiing this unit with my new laptop. I have several pieces of Garmin GPS equipment, and this's one of the least expensive.
Pros: All the capability of the E Trex plus sufficient map storage. Low price.
Cons: Non-captive battery cover. Should COME WITH optional soft plastic case/cover. Won't work in dense woods.
