In order to navigate you need to have loaded a vector file with a point or you can create a point in the Data Entry or New Canvas layer on the app. Once you have the point:

• Click on "Communications Control Tab".

• Click on "Connect to Internal/External GPS" button (depending on which solution you have).

• Wait until GPS locks and the GPS symbol on top or bottom corner  stops blinking  

• Click on the Tracker icon   on the top right end of the tool icons.

• Click on the Point to which you wish to navigate.

• Observe the  instructions (combination of blue line on the map, and compass bearing, eventually, if you wait for it, a direction arrow on the top bar)  and follow them.
