You have a few options:
- You can use the Locate button on the Split Marker screen to locate your current location. The you would need to walk the track and use that to create your split markers.
- You can drive the track one lap and log data. Then use the Overlay button on the Split Marker screen to overlay that data and use it as a guide for choosing split markers.
- If your track or friend has latitude, longitude coordinates for corners or other track locations, you can use the Search button to input these coordinates and place split markers.
An upcoming Trackmaster release will allow you to load your own map image.
