Should be able to do it this way also.
With Cachemate running, tap the lower left "menu" icon on the PDA screen. Tap "option" upper right corner, select register on the option menu.
I use a Palm VIIx w/ 3.5 os.
On the Legend, you can turn off the text for waypoints, poi's and street labels. On the map setup page, you can change the text settings to small, med,large or none. Default setting is med.
However, the waypoint icons will still show on the map.
On the legend, highlight the waypoint that is shown on the map screen.
Push on the page button (upper right on etrex legend), the waypoint info page will come up.
Left click the click stick twice to select page edit. (small icon, upper right of the screen will light up)
push the click stick, then select "project waypoint", enter distance & brg.
The easier way is to look at page26 in the manual.
That little click stick is your friend!
