If you haven't removed the original app then you have first running in background the original one that has no logo to show and only when NavRadio start you can see the logo.I have the paid version of this app. But I did not remove the original radio app.
What happens is that after the car is turned off for a while the radio app is killed. When I start the car, the radio starts playing, but the launcher does not show the radio icon (presumably because the app was killed). I need to start the app manually and then station icon works at launcher fine.
Is there a fix to this?
