Hi all. I'm new to the forums here, and just recently picked up a 2011 Cayenne S. LOVE everything about the vehicle so far except I'm having an issue with phone calls on bluetooth. I can make and receive calls fine, but the sound quality on the other end is an issue. I thought it was a one time thing, but now after a few weeks of making calls and literally everyone saying they can either barely hear me, or lots of static, or call going in and out I'm convinced there's some sort of issue. Anyone else had this and know what it may be?

I'm moving this to the 958 subforum - since that's what your vehicle is. I suspect most 955/957 people have no real experience to share with Bluetooth..

As far as my Bluetooth - aside from sometimes not automatically linking up (usually after I've manually shut the PCM off - or used my phone for my Cayenne diagnostics program that connects via Bluetooth) - it's worked great and most people seem surprised that I'm talking via the bluetooth system.

Hang on while I move the thread..

Whew - all moved!

Hi Tony, welcome to the forums.

Question - have you tried this with another phone? I seem to vaguely recall some people having difficulty with iPhone Bluetooth connections. Perhaps another phone may indicate if it's the phone or the vehicle that has an issue.

Another question, is the PCM taking over your phone in Sim emulation mode? Apparently if you have the Phone Module option (separate line item, but don't recall the option code) it will first attempt to hijack your phone's sim card over Bluetooth and use the PCM and internal antenna for making and taking calls. Unfortunately the in-car equipment either doesn't handle the same frequencies, or is just substandard compared to today's cell phones.
If this is the case, you can go through the PCM menus and change the Bluetooth connection for that device from "Sim Emulation" to "wireless handset" mode.
The acid test is to look at your phone when it is connected to Bluetooth. If it shows you have no signal (or airplane mode), the PCM has hijacked your sim.

I had to dig in and find out how to make the switch as I use my phone as a wireless hotspot for my kid's iPad. When the PCM hijacks the sim card, hotspot or any other data functions quit working.

Anyway, if that's not it - could be the thermally insulated glass(if you have that option) interfering with your cellphone signal.

No issues with calls on mine, however, when using BT for driving directions off the phone (e.g. waze) there is a huge delay before it goes back to playing music.

I have the same issue. I have a samsung S8. This is the third phone I have had with this car. This is the worst it has ever been. It kinda sounds like crackling cellophane. Deleting the bluetooth profile from the car and repairing it seems to fix it for a while. I am not sure why it comes back, but it does come back.

Not sure why you'd say this as the 2009 & 2010 957s have the updated PCM with touchscreen and bluetooth phone connectivity for calls (not for streaming music), like in mine, and it works fine with my LG v10 Android phone.

AGARubberDuck, can't imagine how long it took you to figure out the SIM takeover in your post, but kudos to you for doing so.

Make sure your air conditioner isn't blowing on high. The wind from the unit can make for a very blustery conversation

Thanks everyone for your feedback. To answer AGARubberduck the PCM isn't hijacking the SIM card.
My issue sounds much more like what genebopp described. I'm going to try what he suggested to fix it. Hopefully that works. Short of replacing the microphone in the car I can't imagine what else it would be, and that doesn't sound like a cheap repair.
