Driving back from the dealer I thought my 2020 View with the 10" MBUX system only had an in-dash center speaker - adjusting the balance did nothing that I could perceive. Reading on the Sprinter forum, I found that other folks had noted this issue and were able to disconnect the center speaker and were getting improved sound overall from the door speakers - some were upgrading the in-door speakers and more as well, but I just wanted the separation and some improvement in sound quality, so I tried it and it really does work.
So if anyone is interested:
1. Remove the speaker grille at the center of the dash (it can be pried up with a plastic tool and popped out).
2. Pop out the speaker.
3. Disconnect the BLACK connector only - the white connector is from the SOS and Mercedes Roadside thingees and will still work fine.
4. Pop the speaker back in
5. Pop the grill back on.
6. finished.
I tested it by listening to the radio, pressing the roadside assistance button, and did make an SOS call (the light was flashing and roadside said to push the button to make it stop - it didn't, but at least I now know that the functions all work).
