Iphone Does not play Youtube music or songs when conencted by Bluetooth on Suzuki Vitara 2018 Car Radio

Hello,

I am using a brand new purcahsed Suzuki Vitara 1,6 2018 and everything worked fine but since two months i am having an issue with the Suzuki Radio where i am trying to connect the radio with my Iphone bluetooth and the calls are being accepted and works fine but Carplay with Iphone doesnt play sounds i get this error when trying to hear the music on my iphone? I have updated to the lates 12.0 iOS version.

Can you maybe help me?

With cable everything works perfectly and when connecting by bluetoth i get all phone calls normally but songs are not being played and i get the error Device does not contain media files.

Is there a fix for this problem ?
