The driver also gets a new 12.3in instrument cluster with a choice of four display styles, including a new Off-road mode that shows steering angle, heading, incline angles and music fun stuff. Like on the C-Class, the cabin can be entirely customised with biometric authentication. Just scan your fingerprint and the GLC will set up the seat height, steering position, ORVMs, climate control, ambient light and even the radio station that you prefer most! Hey Mercedes, the built-in voice assistant gets constantly updated too, along with a more drollery, but hey, if you want to use Siri or Google assistant, there is support for wireless Apple CarPlay and Android Auto mirroring. Adding to the wireless theme, a wireless charging pad is conveniently located near the cupholders too. USB-C ports all around make up for any wired requirements you may have and if you want the absolute best from the 15-speaker, 710-watt Burmester sound system, I would recommend plugging in your device for better lossless music reproduction. A personal sound profile tuning option lets you configure the system to your tonal choice and could be a better option than toying around with EQ settings all the time. As is expected from Burmester audio systems in most Mercs, this one too is expansive sounding with a real authority and detail to the bass and an airy top-end that simply fills up the cabin with music, letting you forget about all the speakers and electronics.
