RD45. Another bad bluetooth audio quality..

[psrkallez06]

Peugeot 308 2009. Upgraded from an RD4 to rd45 (aliexpress) everything worked fine. Suddenly i noticed that the Bluetooth music audio is terrible. Especially the highs. Im sure it hasn't always been like that.
So i got an oem rd45 with a later firmware version. Programmed everything with diagbox. Still SAME ISSUE. So now I'm wondering if it is an android update on my phone (galaxy s23). Gonna try with another phone tomorrow. But still. Very weird since the sound was good before.. I first taught that one of my speakers was broken but nope.
I tried with a Chinese aux Bluetooth adapter and that sounds much better. I really wanna use the rd45 internal Bluetooth without any adapters for calls and to see what song is playing on the hud. Any ideas?
I don't have the jbl package.
Thanks.

A few years ago I had a problem with a Motorola phone that stopped working with the RD45 after a software update, and it started working again 6 months later after another software update.

Yepp.. Just confirmed. On my galaxy s23. Bluetooth sucks. On my galaxy tablet with older software its fine..
Tried to turn off Bluetooth offload in dev settings.. Same thing. Any ideas? I don't wanna use aux or usb

If it is using a lower firmware version. I would suggest installing the 4.3.0.3 firmware. The details and files can be found elsewhere.

There is a history of poor bluetooth audio quality on the S23, eg, https://eu.community.samsung.com/t5/gal ... p/10736996

3.2.0.6 = can't be done. Buy a newer head unit with a 4.x firmware and go from there.
