Hi. New to the forum. Just got a low miles 2008 AMG CL550 with Premium Package 2.
Have seen many similar threads about setting the analog clock. I think I tried everything. The analog hands don't move. Went to vehicle settings/time/chose USA/EST/DST, but analog clock still one hour ahead.
Is there another approach that instructs the car to sync with Navi time?
Would appreciate guidance, guys!

Found solution: engine cannot be running. Works fine in Accessory mode.
