Sport clip + with Ford sync issue.

Hi, I am able to play music wirelessly from Sandisk clip sport + with my 2016 Ford Fiesta sync system, but when I plug into the usb to charge it the music stops and the Sandisk becomes unuseable, it just says ‘charging’ and won’t respond to an button pressing. Then it works fine when disconnected. The Ford recognises it as a device on screen but says ‘cannot connect to device’. Any help appreciated.

Ps My Sony experia worked flawlessly with all the song info on screen and voice activated instructions of what to play working fine. Am I able to do the same with the Sandisk?
