Hello @all audiophile XC90 driver, after having completed a test drive in the XC90 with summum equipment or enjoyed it, I would like to say that I am extremely disappointed by the premium sound system. I know, here in the forum there was certainly already the one or other thread about it. Nevertheless, I would personally like to know which system you would advise me on. I am seriously thinking that Summum package to cancel and instead to switch to Momentum (incl. 18 ́s Atlantis, Xenon, tinted disks, Inscription Tuscany brown, Inscription wood, Alarm etc.) . Given my option list would therefore only be the electric driver seat and the famously infamous and strongly criticized premium sound system “misses”. I really fit very well. What do you mean to my criticism regarding premium sound? Have you had similar experiences or is it perhaps a matter of attitude? For example, the surround setting was even a hindrance to the sound of the musicians.
