I don't have the volume problem.

Ok great but I don't want to turn the whole system off, any way to just kill the stereo while keeping navigation working...without just muting system?

I'm ready to crack open the PCM and rip the Tuner module out.

I believe this is caused because you have two or three volume sources and they are not all synced. If you are getting blasted when your phone is disconnected you are most likely using the volume on the PCM to accommodate for low phone/app volumes. As mentioned above, make sure these volume controls are turned up to a reasonable level. I would put your PCM at volume you can tolerate then connect the phone and play with the phone and app volumes until you have decent results. If this doesn't work then the volume coming out of the phone may just be too low.

I've turned up the volume on my iPhone to max. I've turned up loudness and +1 treb and +1 bass on AUX BT. I've turned loudness off on FM. Will see how that works.

I just tested with Spotify and iTunes. I put my iPhone 6 volume and the Spotify App volume to max. Then I adjusted the PCM to a decent listening volume. I turned the car off. When I turned it back on the volume was at about the same volume I left it. For what its worth, audio quality on Spotify is not equal to iTunes. Good luck.

But when you turned the car back on, did it flip the radio tuner again by default? And you're saying the radio volume was similar level to your Spotify volume?

Maybe it's app-specific. iTunes songs in my playlist are at one volume, but streaming iTunes Radio or Pandora is lower volume for some reason.

Either way, there are two problems:
1) the switching back to radio by default (no configurable "default" setting. Ideally I'd have it default back to AUX on power cycle even if last used was AUX-BT)
2) the AUX-BT source not having independent volume settings in the PCM from the radio source volume

Poor design and QA, Porsche...

I don't have the problem. I do stream audio from my iPhone most of the time. I set the iPhone volume to the highest setting and then modify the in-car sound level with the PCM ****. When I start up the car it does default to radio (hate that) but the volume level is fine - the same level I left it in aux source mode.

Are you using bluetooth for streaming, or headphone jack output?

MayorAdamWest

I fixed the problem by just attaching the USB cable to my phone. The volume level then matches.

GregJGT3

Bluetooth...

Interesting. Are you streaming local audio files from the Music app, or streaming radio from Pandora / Spotify / other?

With Pandora on max, it is still low audio level relative to tuner.

somehow between yesterday and today I fixed the volume issue between BT and FM radio.

I think I set the BT "set TP" volume to max (11) and the FM to min(1), but I'm not positive if this was the fix (did lots of PCM configuring yesterday)?

who knows what this "set TP" volume means

Mech33

Interesting. How did you set FM to 1?

I also configured "volume adaptation" to max (6) for both AUX and iPod (although it didn't specify BT AUX or BT iPod) under Jukebox.....

not sure why, but all volumes (FM Radio, BT streaming of Pandora, Spotify, LastFM, AHA radio, iPod via AUX or USB connection) are now the same!!
