You must have at least 1 TomTom map stored in the root directory of your SD card. You must have at least 1 NetChaser log file stored in the directory /Palm/Programs/Netchaser on your SD card.

APmapper converts WiFi access points detected by NetChaser (from Bits'n'Bolts) or WiFi-Where (from Hazelware) to the OV2 format so they can be displayed as Points Of Interest on TomTom Navigator 5 maps.

For Netchaser, you can choose to export all the access points or only those without security (no WEP nor WPA).
