Hi!

So I am having this really strange and annoying issue with my family's new 2021 GLC300.

When listening to the radio, it works for about ~2 seconds. Then goes silent for 10 seconds, shows "please wait...", re-loads all the stations, and the cycle continues.
I reset the whole system to no avail. A couple of weeks ago I accidentally damaged the right side mirror and had to replace the front mirror cap. Oddly enough, this issue started happening a couple of days after that, though I doubt that they are connected. It seems more like a software error, since the radio does indeed work fine for those two seconds before it cuts out again. And I also doubt they would put the radio antenna in a rear view mirror.

Here's a quick video I took: (In the video it's set to a random frequency, it does play music if I switch over to an actual station)


Would appreciate any help!

Hi, did you manage to get this fixed? I have exactly the same problem on a brand new Sprinter with the radio repeatedly resetting, same on DAB, AM & FM so the unit is unusable !

Hi, Did you manage to get this fixed? I have exactly the same problem on a brand new sprinter AWD, it happens on DAB, FM, & AM so the radio is completely useless!

it actually fixed itself after about two weeks. no software updates, nothing. just started working again.

Hello Paul,

Did the problem fix itself for you too? I'm having the exact same problem, the radio had this problem directly after I bought the car (second hand), then it worked for two days, and then it had the problem again and still.

For me the problem fixed itself eventually too, after a 2000 km trip to France and back (to The Netherlands).
