F150 2010 PX6 Screen stays Black

[keevge]

Hello,

I recently purchased a Ford F150 with Sync 1 and auto AC.
The previous owner installed a PX6 radio and told me it didn't work. After starting it shows an Android error.
Now I installed it again and now the screen remains black.
The AC control works, the button lighting works, the original radio continues to play music, only the PX6 display remains black.

Can you reset the device? Or could I have made a mistake when connecting?

Thank you very much and greetings from Germany

Kevin

My screen went black once and the music was still playing ,had me thinking the screen was toast but after rebooting the radio the screen was back to normal
