The RRS 2010 I purchased was sold as having the above sound system which I strongly doubt as there is NO Logic 7 badge on any speaker grille - Is there any other way of establishing if such a system is installed?

Another thing to check is whether you can choose between "Logic 7" and "Stereo" in Audio Settings on the centre touch screen. Current: Volvo XC90 T8 Inscription Pro PHEV with some optionals on top
Gone: MY16 RRS2 3.0 SDV6 Autobiography Dynamic, Carpathian Grey & Santorini Black Sliding Pano/Ebony & Ivory 2 Tone
Gone: MY13 RRS 3.0 SDV6 HSE Black Edition, Orkney Grey/Ivory
Gone: MY09 RRS 2.7 TDV6 HSE, Santorini Black/Almond

Thanks for the above - will check and revert back shortly.
