The Sony XAV-AX205DB could be a great option if you want to keep your current car, but feel like youíre missing out on the latest infotainment technology. This double-DIN replacement head unit has a classy, minimal design dominated by its 6.5-inch colour touchscreen, for a factory-fitted look. It features a DAB+ tuner to give you access to a wide range of stations, along with a DVD player with video out connections and the option to connect a rear view camera that is sold separately. Perhaps most excitingly for smartphone users, itís also Apple CarPlay and Android Auto compatible, so you can enjoy many of the features, music, telephony and maps from your phone, via the touchscreen.
