I also had the low mic volume problem when I installed my b/t module in my 01' X5. I got the new mic and moved it to the sunroof switch location.

The switch opening is slightly larger that the mic openinig, so I had to put a shim on the mic to get it to not rattle. The sunroof switch was a tight fit in the mic opening. It helped a little, but I still get people telling me that I sound "far away". I tried to get Advance Autovations to help solve the problem, but as you have probalby read, they are no help at all. If anyone else has any suggestions, I am all ears.

Just beat me to it, that confirms it

I hear you Blue.. That is the exactly what people tell me that I sound far away.

How do you guys pop out the switches?

Does the newer mic help? Can I add more then one mic?

You can only hook up one mic.

There are pretty good instructions on mic replacement in the "X5 Series (E53) Adv. Autovations Installation Manual (PDF)" here: http://www.advancedautovations.com/manuals/

Good luck

Thanks, good link.

Did you upgrade the mic? Notice any improvement?

I just ordered a new one, I'll report the results next week.

OK, the new mic is in and the position has been switched with the sunroof switch. I can confirm that the 2005 sunroof switch is slightly longer, by 1 mm. All I did was place some doubleface tape under the retaining clip for the mic and that snugged it up. The new mic sounds much better. I have the old mic in my 530 but I gues the larger cabin size of the X5 allows for more backround noise.

I just received and installed the new "762" mic. All I did to test, was to make a call to my answering machine at home leaving a message with the old mic, and then the new one. I can say that the new mic is clearer and does a better job than my old mic part # 84318380338 at diminishing background noise. It's not light years ahead, but it is indeed clearer. Note to benathon, in neither test did I sound "far away".
