Hi everyone, I've recently taking ownership of a 2014 Passat Executive. An amazing car so far, its fitted with the rns315 which connects to my phone no problem, can make calls ect, but it has a problem playing my music, some days it'll work no problem and play just fine but turn the car off to pop into the shops and come back and it won't work? Can sometimes sit for 30mins before a journey trying to make the music play, does anyone have a fix for this, is it a common problem? Any helps much appreciated

Thanks
