All,

After tuning my after market amp on my E90, the Bluetooth suddenly has issues. When making a call, lots of echo and reverb when I talk to the other party (other party can hardly hear me with the echos and reverb). Also, the Chime sound used to be loud and clear, and now, very low sound. Tried to make adjustments on the menu and can't get the chime sound back to the loud and clear status.

Anybody experience that kind of issue?

Did you start out with I drive or pro radio?
Which of the three BMW sound systems did you start with?
Model of aftermarket parts and how are they wired.
MS-8's have reported echo problems.

ctuna… I have the JL audio XD600 wired into the technic wire harness to the stock Hi-Fi system... case in point, this noted symptom began when I started tuning/tweaking the amp... Could there be correlation?

I don't think so I have the same amp and didn't have any problems.
Under seat gain on mine is about 11 am and Front doors barely turned
up with Jehnerts on the floors and morels on the front doors.
Rear speakers set a zero with -4 fade on the rear stock speakers.
Since the stock speakers are 2 ohms in that system they are getting
100 watts rms.

With the stock door speakers at 2 ohms and meant to handle only about 25 watts
you can't have any gain on them maybe a little on the floors.
I ran my stock speakers for few day's but I was careful not to slam it.
