The only way to access information on the Africa Guide is via a POI on the GPS map on your GPS unit.

Once you have chosen the POI you are interested in on your GPS, press the “menu” button on the side of the eTrex, and then scroll down and choose the option “Review Point” on your GPS screen…a photo and information will pop up if it is available for that particular point.
