When using Sygic GPS Navigation or Sygic Truck Navigation (or other applications that use GPS) via CarPlay, sometimes the app will not find or update your location/current speed. This happens when you connect your iPhone or iPad to a running infotainment screen via CarPlay and then launch an app that uses GPS before the app acquires your position.
Solution:
The currently known fix is to start the app on your iPhone/iPad before connecting to CarPlay and wait for the app to acquire your position. Follow these simple steps:
Open the Sygic app on your iPhone.
Wait for the app to find your location
