1. You will need an old credit card (or thick card), a small drill or hot needle, and some pins.
2. Take the credit card and carefully cut it to size. Use sandpaper to shape it.
Three holes should be made with either a hot needle or small drill. You will need to
position these holes so the pins will mate with the eTrex correctly.
If you use a hot needle, do it from the bottom side so that any excess melted plastic
doesn't interfere with the mating surfaces.

then hole 2, hole 3 and hole 4.
