The Bose system in itself degrades audio quality. There are some speakers there that leave much to be desired, especially the center channel and surround speakers, the tweeters and the subwoofer are all substandard. Hence, in my view, providing digital or analog input doesn’t make much of a difference. Maybe only marginally.

I started to notice a significant difference once I started to upgrade my speakers.

You can see my story here: My 2015 Porsche Macan Audio Upgrade Log

This is why I say that for folks with a Bose system, going through AUX may not matter, as the gain by switching to iPod may only provide marginal gain. For these folks, I recommend just go through AUX and forget about trying to find a workaround.

thank u for the clarification . I think Bose sucks too but I’m not big into the audio stuff so as long as it sounds normal and the wife won’t complain I’m gonna give this a shot!

Good song. And that's the set up I initially had with my carplay unit which also allowed me to switch tracks from the steering wheel. So does it seem to work reliably or connection drops?

More testing required. Give me a few days on this to perform full test.

I just turn the car off, locked it, waited for about 10 minutes, went back in and the CarPlay connected very fast with no issues and interference. Waited for AUX BT to show and connected via AUX BT. No conflicts of interference so far.

Audio is very good.

The only difference between this connection and the iPod are the following:

1. When in AUX BT, only can see the song being played in the MFD. With iPod you can see the song, see the playlist and select songs from MFD.

2. Changing songs is smoother with AUX BT. With iPod you seem to need to wait a couple of seconds into the song before jumping into next one, if you do it too fast, instead of jumping, it goes back to the beginning of the current song. That doesn’t happen with AUX BT.

Does this audio problem caused by AUX only affect wireless CarPlay (or AA)? If I plugged my iPhone into the USB port and selected iPod on the PCM, in this scenario does CarPlay work properly and with better audio?

That’s exactly what I’m doing to get better audio. However, you need to setup WIFI CarPlay.

There are some compromises, like you won’t be able to hear turn by turn directions from Apple Maps or Waze, as these apps want to route their sound via CarPlay. You should be able to setup Google maps to work on this scenario, as is the only app where you can select output. That’s with iPhone. Not sure with Android.

Thanks. If that’s the worst of it, I can probably live with it. I happen to prefer Google Maps over the other alternatives anyway, and have G-Maps set to output its audio to play as a Bluetooth phone call, which I assume is what you‘re referring to.

The degraded audio is very noticable on a Bose system. Especially when playing FLAC files. I'm not an audiophile by any means but I do love my music and to my ears the bose system is perfect (although I do take on board what you say about centre speaker, it's crap!).

Good this works for you on Car Play. Unfortunately Android auto does not allow you to change how audio is routed and takes over Bluetooth and forces audio via AA. No way around it!

Correct.

But what I understand is that the issue is not necessarily the CarPlay module, but rather the native PCM AUX input that is user by the board, which is crappy.

Konkab is trying some solutions that you can try to improve audio quality.


Sent from my iPhone using Tapatalk

This. As Konlab has said audio is greatly improved when using the aux to usb adaptor (which by the way I have ordered the same but locally).

I understand why you want a digital signal over analogue however a good analogue single behind a DAC will be just as good as a digital counterpart (think high fidelity balanced audio headphones which are all analogue). I think for short runs analogue signal is very much adequate providing the cable quality is decent and the DAC is fairly decent.


As for PCM aux I really don't know why it is so rubbish. Must be the built in DAC amplifier which handles analogue signals.

the surround speakers are exactly the same crappy speakers as the center channel.

More testing of AUX BT today. Surely the AUX BT option is much better than AUX in terms of audio quality. It is not quite there with the wired iPod quality, but pretty darn close.

With the iPod input, as I said earlier, I can’t hear turn by turn navigation from Waze or Apple Maps when in WiFi CarPlay, but can hear from Google Maps.

When in AUX BT, I see the same behavior from Waze and Apple Maps. However, Google Maps lower the music volume as if it wants to say something, but no voice comes out. Hence, Google Maps doesn’t work with AUX BT when in WiFi CarPlay.

No dropped connections so far, so, I’m assuming that the conflict/interference issue had been fixed with this module vs Joye.

Don16 - great video! Really good job. One question about the 2 cables coming from CarPlay board that you squeezed through the antenna hole in the chassis .... do those connect to anything in the car? Your video shows you connecting extension cables provided in the kit to the plugs of the 2 cables passing through the chassis, but I don't see in your video that the extension cables' other ends were connected to anything in the car. Are they just left unconnected?

I know you ask @Don16…. He can provide more detailed, but if I remember correctly, one of them connect to the Quad harness that goes between the PCM and the OEM Quad plug. There is a plug on that harness. The other is the AUX USB input.

If BT solution works long term I guess I'll have to bite and upgrade too.

Yes. One connects to the quadlock loom included in kit (this is what routes the audio aux direct from CP/AA board to back of pcm3.1) and second connects to the other loom included which has the usb female input.

Yes the quadlock loom that comes with the kit diverts the aux (L, R, ground) wiring to the carplay module. It's why the aux port in car stops working.

Any further feedback on aux BT audio via OEM and carplay via module? Tired of wasting my burmester speakers on chitty joyauto aux.

 

[Santirx]

Question - did you get interference/hissing in standard form using intended Aux? I'm trying to remember if I always had interference/hissing prior to modifying cable to route audio via aux to usb adaptor.

I know factory AUX setup (when not using CP module aux) there is zero interference/hissing. But I can't for the life of me remember if I had the issue before I messed with wiring.


I'm starting to think the solution is to disconnect the ground wire going to the CP module board, only because the interference/hissing starts when car is started and changes pitch with AC fans switching on.

Sent from my SM-G960F using Tapatalk

I don’t remember any hissing from AUX.

The interference I was referring to was the conflict between “Joye” Auto board Bluetooth and the AUX BT.

My board is similar to Joye but rebranded as MediaShoppe. I didn’t have to connect a wire to the fuse box like many Joye modules seemed to require. That was different.
