I just wanted to say that I found this thread a couple of days ago and it's been invaluable - thank you!
I have a '12 Cayenne and have wanted AA for a while but didn't fancy the idea of a separate box/power supply as well as the board in the PCM - the Isudar board looks like exactly what I'm after.
I will be placing an order pretty soon!

 

I will re-enable the wireless connection and test the key fob range for a while before I do anything, I have to agree, if it isn't broke...

 

Why not just leave the car running while it's updating?

 

Quick question:
How does AA (and CP) work alongside listening to normal radio on the PCM - can I listen to the radio and have the satnav working at the same time or would I not get sound from the Isudar board?
Or is it not possible to listen to the radio when AA is running?

Thanks.

 

The Isudar board uses the AUX input on the PCM, so whenever you are using Carplay/Android Auto you will be using the PCM in AUX mode. That means no other inputs are available on the PCM at that time (eg Tuner, CD etc). Aftermarket Android head units have their own built-in FM radio so that can be used alongside CP/AA, or a satellite radio module can be added for DAB (in the UK) and US users can use Sirius/XM via an app for 'HD' radio.

One option for Isudar users is to use an app for streamed radio - one that is compatible with CP/AA. I use TuneIn Radio and/or Replaio and both work pretty well and give me a choice of thousands of stations, which IMO is better than the few that are available on FM. I regular listen to US Jazz stations for example which would be impossible in the UK with 'normal' radio. This means I can listen to radio and use satnav etc via CP/AA all at the same time. Works very well IME.

 

Hi ZedZed
Thanks for the info..... I thought that might be the case having seen the requirement for the Aux input to the enabled on the PCM.
I don't think it's much of an issue as I think I can just use the BBC Sounds app which seems to be compatible.

 

I generally don't have the vehicle running during code updates, any work on the 718 PCM was done with the engine off. I bought a specific battery maintainer for doing work like this as the usual suspects like a CTEK maintainer can't keep up with the battery demands of most cars when the ignition is in the on position, engine not running.

 

I disagree...

Yes it is, I do all of the time... ***UPDATE*** but there will be no audio from AA/CP

 

I followed the installation instructions to the letter including enabling AUX BT IIRC, and I recall a message about sound using that while AA is running. All of the details are in the installation guide, or have you run into a problem?

 

How does that work? How can you have the PCM input set to Tuner and AUX at the same time?

Surely if your PCM is set to Tuner, you won't have any sound from CP/AA satnav (via Isudar) coming through AUX? Conversely, if you switch to AUX for satnav sound (via CP/AA), you won't be able to use the Tuner input.

Even the original PCM will kill the radio if you switch to a source connected to AUX, so that it can play the content connected via AUX. Just like you can't have CD playing and radio playing at the same time (for obvious reasons). The OEM PCM can, of course, play radio and Porsche satnav audio at the same time, but that is no different to Android Auto playing radio via an app and satnav sound at the same time - a totally different thing.

So just for clarity, you can have your OEM radio playing via the PCM and at the same time you can hear satnav instructions via CP/AA?

What am I missing here?

 

The excellent Isudar user manual is available online so anyone thinking of going this route can check everything out before committing:

Yes, BBC Sounds is compatible with CP/AA (or was the last time I used it anyway). I can't really see the point of old-fashioned 'hard' radio any more. Just as 'hard' music via CD has been more or less totally replaced by streaming apps like Tidal, Spotify, Qobuz, Amazon Music, YT Music etc, for me streamed radio via TuneIn or Replaio (or many others) is just way better, with so many more stations to choose from and CP/AA compatibility too. If you have a music streaming account, the good news is that they all seem to be supported by CP/AA. I use Tidal and YT Music more or less daily for my playlists in the car, and TuneIn for radio content. All seamlessly integrated. My wife still listens to some music from a USB drive, but she admits it is only until she gets around to recreating the content via Tidal playlists. The good news is that we have these choices I guess, so everyone's needs are catered for.

 

This is much like when there was no Isudar board installed, you can listen to FM, media and CD's and if you phone is connected into the PCM and a call comes in the radio is muted and the audio for that call comes through the PCM.

See Post #1704, IIRC the audio for the Isudar board will come through the AUX BT connection. We have the phone wirelessly connected to the Isudar/PCM and Google maps up and running, all the while listening to FM, when the map needs to play an audible direction cue, it mutes the radio, and the directions are heard through the PCM system.

***UPDATE*** When listening a source other than AA/CP you will not hear audio directions from a navigation program running on AA/CP

 

That is a different thing. See my revised post above where I attempt to clarify what I am saying. You can listen to any source via the PCM and the satnav audio still plays because there is no separate audio channel for the satnav on OEM. OEM satnav sound plays regardless of the PCM input selected. But with Isudar, sound from CP/AA comes via AUX and it isn't possible to connect to two different PCM sources at the same time. What happens when you select CD input on the OEM and you are using satnav via Isudar/CP/AA?

Obviously, I am not doubting what you actually hear in your car! I just can't understand how you can select Tuner input in the PCM and then use AUX input for Isudar's sound. I must be missing something fundamental. I never tried this when I had Isudar since I stream my radio and music content via AA. Maybe the Isudar board is somehow hijacking the tuner input on the PCM? If it is, that is really clever, and it is a good bonus benefit of the Isudar system.

 

You keep saying 'AUX' and Isudar in my configuration is using 'AUX-BT' for AA audio.

Did you enable this feature on your PCM?
