Since my last post hasn't been posted/activated for some reason I give it a second try...
Is there a firmware update available for the following MCU?

Hello Jammy,

thanks for your reply. Unfortunately I don't have an order number because I bought it on Amazon.
Item number should be the following (label on the package): AA0482B-A01

Best regards

Hello,
Would you mind to tell us why do you want to refresh system or MCU?
Is there anything wrong with the autoradio?
Refreshing system risk of damaging autoradio, it is better to work with original version.
Best Regards,
Jammy

Handsfree system is very low and there is some background noise. It doesn't matter if I use the internal or any external microphone (I have already tried three different external microphones).
Maybe there is a firmware update available which resolves that issue.
Or is there any setting I can adjust?

P.S. Ignition control for illumination isn't working as well.

Thanks for nothing, Pumpkin... I have flashed the firmware by myself and it's working well...
