On January 17th, I took delivery of my 2018 GLC 43 Coupe. Shortly thereafter, I discovered a problem with the hands-free calling functionality of the Comand system:
Incoming calls ring on the car’s speakers and the caller ID shows on the Comand screen. However, when I answer the call using the steering wheel button or the Comand controller, the audio terminates on the phone, not Comand. I.e., the audio plays on the phone speaker and does not play over the vehicle speakers.
Outgoing calls exhibit the same behaviour.
In both scenarios, when my phone is idle (i.e. no active calls) both Comand and the phone show that a Bluetooth connection between each other is active. Comand is able to access the phone book on the phone and retrieve both text messages and emails. Everything works as expected, with the exception of phone call audio.
I took it to the dealer and they did a bunch of testing with my phone (BlackBerry Passport) and several employee phones (a mix of iPhone and Android) and got the same results. They also tested with a 2018 C Class in the showroom and the behaviour was exactly the same as with my GLC.
The Comand software on my car is up to date. At this point, there is nothing the dealer can do other than open a ticket with Mercedes-Benz Engineering in Germany.
Since the problem occurs with BlackBerrys, iPhones, and Android phones on multiple 2018 (Canadian) vehicles, I shouldn’t be the only one out there experiencing this problem. However, I am the first customer the dealer has had complain about this.
I’m curious If anyone reading this has had this problem (and found a resolution).
