The Volvo XC90 is one of the best large luxury SUVs on the market. One of its most distinctive traits is its suite of audio and tech features. Like the other SUVs in the XC line, the XC90 has a very generous base trim that provides more than the base trims of its rivals, like a 9-inch touchscreen, smartphone connectivity, wireless charging pads, onboard navigation, satellite radio, and a pair of USB ports. Its audio at base is a 10-speaker system, which can be upgraded to have 14 or 19 speakers depending on the trim level. Most of the tech is part of the base trim, but some extras like a digital instrument display are optional, so there are still good reasons to upgrade if it is in your budget and you are attracted to them.
