I have a 2008 LR2 SE that originally came with the Alpine speakers / factory radio. For a few years my Bluetooth kept disconnecting (I replaced the module and that did not help...original module was reinstalled).
So, last year I decided to pay a shop to install a Sony XAV-AX5600 radio with additional wiring to keep using the steering wheel controls. The Sony radio worked for about 3 months but now the speakers are intermittent. I've checked the fuses in the radio system and all are fine. When I pull and put fuses back in, sometimes that gets the speakers working again. Or if I disconnect the car battery.
I'm not sure what could be causing this. Is is the amplifier going bad or something in the MOST ring (which I know little about).
Any help is appreciated.

EDIT: Added 2 photos of MOST lights/connectors. The one lit is to the Amp and the one not lit is to the Bluetooth

Thanks,
Ed

It'll be impossible to diagnose with diagnostic equipment, as the audio controller is needed for diagnostic function to communicate.
You're going to need to use more conventional test equipment, but not knowing how the new HU is integrated with the original amplifier makes an Internet diagnosis impossible. Hyundai Ioniq 5 Ultimate. The family car.
