I have a BlackBerry with Vodacom SatNAV system loaded. BUT I cannot enter Lat / Long Coordinates to navigate to a position somewhere in the sticks where I need to go for my work....radio towers on top of mountains etc. Was thinking of POI's, but is this possible on the BB unit as this uses a server for the latest maps and info downloaded from the Cell network in real time. Any suggestions apart from buying a Garmin or something ?
