Hi, I am also a newbie, so forgive me if Im saying something obvious to the experienced.
It seems I did this totally the other way to the previous posts. I got a gps for walking purposes, making sure it also worked for driving as I didnt have a satnav..... two products in one! Then I found out about geocaching whilst reading the instruction!!!! lol. Errr... guess which one its been used for most since lol lol
