I have the latest 6.15 install a brand new iPhone 4S and sitting a block from a cell tower with 5 bars of reception the Bluetooth sound quality of the built in phone is poor to the point of not being usable. It almost sounds like the audio amp is being driven hard with subsonics so it has very bad clipping distortion, I tried turning the volume down but then you can't here the call. Anybody got any ideas on improving it or is this a 6.16 issue? It's strange because the streaming music audio sounds OK.

Try turning down the volume on your phone to the mid-level, then turn up the volume on the car speakers to compensate. I don't use an iPhone, but that technique has made a dramatic improvement in the audio quality for me using my Dell smartphone. It moves the situation from "totally unusable" to "pretty good." I think you're right that the problem is a clipping issue, but it sounds like it's clipping on the input.

Good thought I'll try that ASAP... Maybe preamp clipping or out of range for the front end A/D or D/A

Go and get a BT to standard Audio device. I'm using Belkin in my office and I did not expect this quality

You could easily check the difference and present it to your dealer.

Having to turn down the volume on the phone would kinda negate the point of using the bluetooth as I'd have to dig the phone out of my pocket while driving.

My iPhone sounds just fine in any other car I've tried it with. Just the Fisker... I should have mentioned this in my big video review the other day.

I am still on 614 and the BT phone quality is actually quite useable. The audio streaming is definitely a lot worse, particularly when the ICE is operating, but I make and receive calls in my car all the time and even use Siri through the BT microphone and speakers without any problems. Did 615 actually make it worse or is it just that BT did not improve with 615?

6.15 does seem better than it used to be, but it's still quite poor compared with other cars.

In my car the BT was totally unusable with 6.14 see list below why:

BT phone would hang the Sat. Radio audio to the point you had to reboot to get it back

BT would not disconnect properly at shut down...I never ran my 12 volt Battery down as others reported but that was probably dumb luck.

BT phone audio up and down was TERRIBLE. I couldn't hear people at all and they reported my audio was almost illegible.

When BT was active the volume control became somewhat flaky.

This phone is an iPhone 4S that works perfectly on Bluetooth with several other cars.

Other than that it was fantastic.

It seems like everything is fixed now except for the phone audio quality.

iphone 4s white which makes it better but anyways the bluetooth is just ok with 6.15, one thing that concerns me is that I do not have an independant bluetooth volume control like some have said. I turn the volume up when I am on a call and then when the call ends the radio is super loud..

Same here...the iPhone does not have a separate volume control on the Bluetooth output. I believe it's direct digital from the stored mp3 file or from the phone chip...so the analog "Volume" control really has no meaning anyway, the bits are the bits.

BTW I tried everything today to get a better setup with the phone ... NO GO. Echos, Clipping Distortion and Feedback.

That said, the streaming music seems to work great, which in itself is a big improvement over 6.14.

My dealer told me that the BT problems were a result of all the variations in the market and the sensitivity of the car's electronics. But for what it's worth, my android phone and BT work flawlessly on 6.15.

That's interesting.
Using my iPhone 4 or my wifes 4s in either my Audi or BMW I can use the iPhones volume controls during phone calls...

After the call, the radio has still the volume, used prior the call...
