GLC Audio/Burmester Sound Profile resetting
Hi. I have a 2026 and I have a 3D sound profile set up. In the section where it has the 4 quadrants and you slide it around to your preference, that part often resets to baseline/middle. Sometimes it goes days and works great at each start up, then other times it forgets my setting/resets 2x a day. Anyone else have that issue?
I'm talking about where you go through the questionnaire and set the sounds the way you like and at the last part you can fine-tune it using the quadrant area. That resets to factory settings. Thanks. My SW appears up to date and I did a OTA update just last week for something else (whatever it needed, it was screen-related I think).

I don't have anything useful to add, but may be user profiles might have something to do with it? Are you using the same key fob, or user profile etc? I am the only driver on ours so far so I haven't really messed with user profiles yet other pairing alone keyfob to me.

Same key, same user profile. And actually trying experiment with "guest" or non-signed in user too. Works the same. It stays in memory sometimes, then other times not. Weird.

You're welcome, as for the reset issue not sure the latest software addresses it as well.
