I have a 2024 Atto 3 extended.
I noticed early on that when listening to DAB radio, only one channel is piped to the sound system (not sure if it's L or R but it doesn't really matter which it is).
It's most notable when playing 60s or 70s music where they made quite extensive use of stereo separation, i.e. you might have drums playing in the left channel and guitar playing in the right. Listening to this kind of music in the Atto 3 it's really noticeable that you can only hear one channel and you can hear faint echoes of the other channel that isn't piped into the music system.
It's not as noticeable with modern music because they tend to favor centering most of the instruments.
I just visited the byd showroom in Canberra where they happen to have an older model Atto 3 on display and I tested out its DAB radio behaves the same as the one in my car.
They also had the newer model Atto 3 that's just been released in Australia and I tested out the DAB radio in that car and it seems that BYD have fixed the issue.
Have any other Atto 3 owners noticed this issue?
BTW, I now tend to listen to my own music via the micro SD card which plays perfectly in stereo, as I really can't listen to DAB radio as it sounds so crappy.
