2005 X5 Bluetooth Sounds Bad
 

Last year I purchased a 2005 X5 4.4i with nav and DSP. The bluetooth works great EXCEPT that the sound quality in the car is very poor. People on the other end of the call say that I sound great, but I have a hard time understanding them.

For lack of a better description, the phone audio is ALL midrange without any high end. It sounds "honky" making the phone unintelligible. The radio, CD, and aux input (iPhone) all sound great. Is this characteristic of the Bluetooth module, or is there something wrong with my system?

Maybe it's your phone. I have to same year and mine sounds great with my present phone.

I suppose that's possible, but I use the same phone (iPhone 4) with another Bluetooth speaker in a different vehicle and it sounds fine there.

My hunch is that you have a problem. The BMW BT system is one of the best in any car at any price.

The audio feeds through the DSP amp to the speaker. So, the three possible causes are the BT module, the amp, or the speaker. It could also be the BT antenna, but that would likely distort your voice to others.

Thanks for the replies. Any ideas on narrowing things down? I don't have a spare BT module, so swapping that out isn't an option.

Pair someone else's phone.
