carpad 3 - Can not hear audio after activating radio app

After boot of the Newsmy carpad 3 I can play and hear audio in the Music app and hear Waze's navigation directions.
Once I activate the Radio I can not hear any audio again from other source than the Radio.
Even when I close the radio app and "FORCE STOP" it, and activating again Music and Waze, there is not sound from these apps.
From now on, only the radio can be heard.
I have to reboot again and not to run Radio to play mp3 files with Music app and hear Waze's directions..
Any help, Please?
Thanks.
