Hello
I have a 2010 Porsche cayenne 957. When I went into the parking assist for programming it lowered the volume to 25℅ automatically. And since then whenever I raise it and save the setting it won't save. I tried several times with different volume settings (50%-75%) but the same thing kept happing the volume won't change and kept at 25%. Can anyone guid me if I did a mistake or if there is a bug in the software.

Thanks
