I am very disappointed with my EQC 400 navigation performance. As I got the car last year in November and after 2 months Navigation screen went blackout. The local Mercedes dealer replaced the screen but it never worked properly. Most of the time navigation location is out of calibration not show current roads on the map. I went several times to local Mercedes dealer but finally they were unable to fix it and unable to help further. So I am using my Google maps on my phone in Mercedes EQC 400.
