Hi Mike, Hi everyone,
Here i am with the same problem someone else had.
The "non beta" version worked flawless!! Navigon was on the display of the head unit, and safari too. Additional apps were on the menu of the app radio.
Tried many times beta version 2, and was unable to get the tout to work properly. Hoped version 3 fixed it, but today i tried it, and i have the same issue.
Rebooted after installation (with file), erased manually all of old files related to appex. Nothing seems to work!
I see correctly app radio extensions in the preferences, i see additional apps in the Head U
