Does it fully mute the radio during navigation instructions, or partially attenuate (in other words, can you hear the radio while it is also giving navigaiton instructions)?

Yes, yes and yes
It is fully working, real BM54 with AUX, MP3 CD Text and it does not fully mute audio during navigation istructions and speed camera alert.

Think that BM24 has very different hardware, not sure even the flash memory is the same, like BM54.
BM54 firmware update of is possible only with programer. I`ve attached the firmware, so if you have programer (or find someone with), you can update it.
Just remove .pdf extention of the file and unrar it
P.S The flash memory is on the back side of mine PCB, with indication 29f400.
