The Viidure 4K Dash Cam is a high-quality camera designed specifically for the Mercedes-Benz CLS Class from 2012 to 2018. I sold my 2017 Mercedes cls 550 and uninstalled this one so I’m pretty sure it can be used in CLS class. Used about 6 months and everything was ok, very easy to install just follow the tutorial and plug in. You can download Viidure app as well for live monitoring when you driving.
