OK folks got my 2014 C4S today. Connected my cell phone no problem, but since the car was previously owned, it has another cell phone on the PCM. my question is how do I remove it. Can't seem to figure it out. driving me crazy. also how do I use voice dialing. thanks. This car is WAY cool.

 

Voice dialing is an option. Make sure you've got the option before you try to figure out why it won't work.

Congrats on the new car!

 

See below bolded area:

Thanks PorscheCrazy just finished your instructions were great.

 

There is also an option for factory default on all PCM settings.
This will reset everything just like new. So you don't have to deal with any preset options from its prev. life.

 

This worked for my 2017 Macan:

1. Select the 'phone' button on PCM
2. Click the 'OPT' button
3. Select 'Set Phone'
4. Select 'Bluetooth'
5. Select 'Bluetooth Devices'
6. Select the phone you want to delete
7. Select Delete
8. Yes

 

Having previous owners name on PCM for phone is how I got a reference on the preowned car I ended up buying. I tracked down the owner from LinkedIn and asked if that was his Porsche and the mechanical soundness of the car etc when I purchased it at 7K miles. The guy was great and told me it was a great car and why he traded it in.

 

Hey PorscheCrazy - ever heard of this? New (to us) 2014 Cayenne Turbo S. Setup phones via BT and successfully made/received calls and streamed music via BT Aux. Then the next day I hit a few buttons while car was starting up and BT and BT Aux are GONE. I am kind of a geek and have scoured the forums for this to no avail. PCM v4.76. Any options having to do with BT are greyed out. Can't activate BT, phone not available, etc. We reset the PCM and tried every other trick I could find. Any insight?

 

edunne - only thing I can offer are these. You may or may not have done these:

press INFO and SOURCE together to learn about PCM status and history

press INFO and SOUND together to reset/reboot PCM

Also try this



Hope one of these solves your issues!

 

Thanks for all the great info. We have yanked fuse and tried everything above. Took car to dealer for transfer case warranty replacement (yay!) and had them look at BT issue.
See snip of report. This absolutely makes no sense to me. Everything worked and then I pressed some button combo and BT is gone. Nothing else is impacted. Is it a PCM hard drive issue? Some other module? Can anyone help? $3k for new PCM just seems wrong.

 

edunne - read through these posts as they offer some solutions to something similar to your issue, especially post 10

https://www.planet-9.com/threads/blu...ppeared.83434/

Hope it solves your issue.

 

Thanks for redirect. I have reviewed those tips. Unfortunately for me, all BT is gone, not just BT AUX. Sigh...

 

Seems to me that if you BT went off as a result of pressing some buttons, you should be able to get it back. A resent, however, should have bought you back to original. I will continue looking for you, but it does sound very weird.

 

Don't know if you have done this, but you should post on RennList. There is a wider audience there and someone may have had a similar issue and has a solution.

 

I have posted on Rennlist also. Great response there as well as here.
Bottom line - I cannot wrap my head around this being a hard drive issue. A hard drive has a disruption and JUST BT fries? I don't see it. From other posts, I have learned that BT is built into PCM, not a separate "radio" (using old school terms). I can wrap my head around a hardware failure bcs it is isolated but it really feels like firmware or something else.
