radio module modification
 

anyone know how to update the firmware on a bm53 module?

or transfer some electronics from a newer module to an older one?

I replaced my radio module which was 2005 and supported aux

installed a 2001 module which doesn't support aux

is there a way to modify the 2001 to have the same firmware as the 2005

2005 module audio output has failed so I can tear it down

i forgot the website address but if you google "Baris BMW radio" you should come across his website - Baris is worldwide known expert on these radios and the firmware/hardware...
