Front Right Speakers Not Working

[mikem]

I have been without my front right speakers in my E53 for more than two years now and always thought that it was caused by a faulty central screen unit. Today I changed it for a new one as the pixels on the screen had begun to go.

The change over took about 15 minutes and was successful in that the new screen is perfect and all of the functions and presets were seamlessly transferred to the new unit. Did the front right speakers finally work? No such luck!

I wonder if anyone out there can shed some light on the possible problems together with the location of the parts that I need to check. Someone suggested today that it may be a faulty BM54 Radio Module, errrr what's that and where is it? I googled it and there were so many alternatives that I gave up. Any help that leads me to an eventual solution and working front right speakers will be greatly appreciated. Thanks!
