v40

I have a volvo v40 t5 r design and I am experiencing problems with my stop start. Everytime my stop start kicks in at the start of a journey I lose all sound through my infotainment system eg no reverse beeps or any sound from music. This does rectify its self if I turn the vehicle off then on...

Hello all. Just wondering if anybody knows if and when this should be done? I can't see anything in the manual and can't find anything definitive online. It is a 62 plate if that helps. Cheers
