I have successfully loaded the V5 map to my Android Phone which has a GPS. I switch the GPS on and go to Memory Map and click on Start Logging. The cursor moves round as I walk to indicate my current and changing position but it does not track - ie leave the red line to create a record of my walk. What am I doing wrong

There may be an easier way but what I have done is set up a Start/Stop Logging button on the dropdown menu: Tap the screen, then drag down the curved parameter display button that appears at the top of the screen. The parameter display will be revealed; if not, drag that button down. Now long-press anywhere on the parameter display, then choose "Change Data" from the menu, then in any of the data boxes, tap the blue down arrow and choose "Track: Logging Button" from the menu. To get out of edit mode, long press on the data display and then you can tap on the Start/Stop button to log/display your tracks.

To display or hide the parameter display, short-tap the map; the parameter button will appear at the top of the scree; tap it and the parameter display will appear. Tap the button again and the PD will hide. You can also drag down the parameter button to reveal more parameters.

Yep, that's correct. If you have not asked it to start logging it will not.
