I'm attempting to swap the Columbus head unit in my car, for a s/h Pioneer AVH-Z9200DAB because I found I wasn't able to connect my iPhone to the existing bluetooth.

I went to a local-ish car audio shop to buy the necessary adapters for the wiring harness and steering wheel controls.

I've been trying for I don't know how many hours now to solve a problem I'm having of no sound coming out of the speakers. I had several theories, but settled on one which hinged around the wiring in my harness adapter not quite matching the pin configuration of the Quadlock adapter - as detailed in attachment 1.

While researching, the forum this morning I found out it's probably because I have a Blaupunkt 10CH amp under the passenger seat! I feel pretty stupid right now.

Now I have to figure out how to get the audio into that!

I can see there's a pin for Amp on the Columbus Quadlock diagram, but that there's no connection for it on the actual Quadlock plug, also that there don't seem to be any other audio out connections other than speaker connections (unless the green and blue Quadlock plugs are being used.

 

I'd welcome any advice anyone can give before I bite the bullet and pay for the shop to fit it.

 

Thanks.

Check with your Pioneer seller if AVH-Z9200DAB works properly with Sound System. If it is not supported then you either:

- remove Blaupunkt amplifier from the system and install proper crossevers (3-way crossovers for front and 2-way crossovers for rear)

- replace Pioneer unit with another type that supports Sound System, either aftermarket or Skoda MIB STD2 PQ (must be patched first)

- return to Columbus and replace Bluetooth module with some that supports HFP (Hands Free Profile), A2DP (Advanced Audio Distribution Profile) and AVRCP (Audio Video Remote Control Profile).

Thanks for your reply.

 

My Pioneer seller is a private individual, so I wouldn't expect them to know much about compatibility. I've contacted Pioneer directly, will see what they say.

What does Sound System require in terms of compatibility? I'm assuming not all Sound System configurations are the same. I have a Blaupunkt 10CH Amp 3T0 035 456, I've uploaded a photo.

 

Can you give any more into about Skoda MIB STD2 PQ and what patching would be required? It seems like this might be a viable option to get BT and DAB features if the Pioneer unit isn't a viable option.

 

 

Update. I have solved this, thanks to a mixture of help from this forum, YouTube and a bit of help from the shop I bought the adapters from.

I made a new topic detailing what I did and mistakes made here. In hindsight I probably should have just posted all the info in this topic, if an admin wants to merge the two topics that's fine by me.
