Hi all

So just installed a new Pioneer head unit (https://www.pioneer.com.au/shop/car/dmh-z5350bt/). I used Aerpro wiring harness adapters as per the following kit (https://aerpro.com/fp9202k)

Spotify works, Bluetooth audio works if i play music from the phone, no problems.

However when i want to make a phone call either with Android Auto or just bluetooth, there is no sound at all coming through the speakers. If I call someone, I cannot hear the dial tone and once they answer, they can hear me fine, but I cannot hear them. If they ring me, no sound comes through the speakers.

I've trawled the net looking for solutions but nothing has worked, thought it would be a setting on phone or headunit but I'll be damned if i can find anything.

Have tried using Android phone (using Android Auto and straight bluetooth) and iPhone (only straight bluetooth) and neither work.

Anyone have any ideas as to what may be wrong? Is there some trickery with the Bose unit?

Have you made sure you've given access as per the attached (android).
It's in your Bluetooth menu. After you've paired with the headunit, click on it in the list of bluetooth devices.

Yep it has access for calls.

Got it sorted, originally i thought it was Standard vs Network mode so did a factory reset and changed to Network. Phone started working but then there was no music through the front speakers. Then realised I had the FR and FL RCA's plugged into the wrong ones on the back. Plugged in correctly and all working now.

Does anyone know whether we need to use Standard or Network mode?

i had a similar issue when installing an aftermarket pioneer with a factory bose system. usually the problem is that the phone audio (hfp) channel isn’t being routed correctly through the wiring harness. music works fine because that’s a2dp, but calls use a separate line.

check in the pioneer settings under **bluetooth → phone audio output** and make sure it’s set to “front” or “all speakers.” also, some bose systems need an additional interface/adapter to properly integrate hands-free audio. you might want to confirm if your aerpro kit supports phone audio or if you need an extra module for bose integration.

worth testing with a temporary speaker connected directly to the pioneer’s output to rule out the head unit itself.
