Does anyone know how to turn on this digital gauges that display HP and Torque on my C400? When I did the test drive I was able to turn it on but don't remember how I did it. Thank you in advance.
My MY 2016 C300 has something similar... but the right hand "dial" is voltage, not temperature. I'd have to be in the car to remember how to get there, but I know it was in one of the menus under "Vehicle" (not much help, I know).
Sounds like an software update will enable those attractive gauges for the 2015 models.
Good luck - I'd be very keen to hear of anyone who has success in getting this functionality update in their 2015 car.
I think this will be very much dependent on the country of residence, your dealer and how deep you pockets are. Someone on another forum said they got quoted over AUD$1000 to get a full update done to COMAND.
