Hi, I have just taken delivery of an XC 90 SE Geartronic. I went for the option of the High Performance stereo. I am now regretting not having got the premium Dynaudio stereo. I am finding the stereo to be tinny and without much bass of depth of sound. Volvo have been of little help except to say that I should have gone for the premium system. I have discovered that there is a graphic equaliser but so far any adjustments to it have left me with sore ears, even with the volume on low. Can anyone make any suggestions? I am so disappointed.
