Thank you jwq so much, especially for complete pinout scheme :beer:

Now I can order CA-R-PI.017 (if I find some), then headunit :biglaugh:
Is there any other issues that I should be worry about?

Nope, using the PI.017 installation is pretty straightforward (assuming you don't have Bose), as it also supplies the missing switched +12
Don't use the metal cage of the connect, use the cage that's usually supplied with your new radio, as the one for the connect is specific (sell it with your old connect :biglaugh

 

Nice, I'll remember :thumbup:
But what if I have Bose sound system? I can't connect everything straight?

 

If you have Bose, you will need to add the switch-on signal for the Bose amp,(single wire in the yellow mini-iso connector needs to be connected to accessory-out pin of the radio) and depending on what you want, you might want to use the line-out of the radio in stead of the speaker outputs (assuming you have minimum 4 Volt line-outputs), or perhaps need to attenuate speaker outputs in order to have sufficient volume control....

edit: looking at the specs of the radio, it has 2 Volt line outputs, so these would not provide sufficient drive for the Bose amp. This means you need to use the speaker outputs.... Using these as is, you might find that the range of volume control is not sufficient, i.e. turning up the volume knob slightly will already give high output levels. However, you can always first try to see if it's a problem for you. If so, you might have to add an attenuator in the speaker outputs....

On the original connect, there is an input on the HU that indicates to the connect that the system is used with Bose, causing the speaker outputs to change to high-level line-outs (~5 Volts). This allows alfa to use the HUs with both Bose and non-Bose, without needing to change the HU connections..

 

Should I connect pin C.6 to another pin (I haven't dismount Connect-Nav yet)?
If that would provide volume level that can be compare to current one, I'll be satisfied.

 

As said, you would need to connect C6 (loom side) to connection 12 (installation manual page 3, Pioneer MVHAV270BT - Support & Pictures) on your new HU in order to assure the Bose amp switches on.

Re volume, I would first try it out.

 

Thank you again for all advices!

Now it's time to make some orders, but that can take time, because CA-R-PI.017 isn't available in many places.

 

if you can't get the Pioneer adapter, you can Always look at the connects2 stuff, see fi
CTSAR003.2 Alfa Romeo 147, GT Steering Control Adaptor

p.s. disregard any comments on car production years, for some reason they always (incorrectly) mention pre and post 2007 etc. on internet

 

After 3 weeks delivery I've got my CA-R-PI.017 !
First from France to Spain, where lives my cousin, next from Spain to Poland.
The only shop where I can find CA-R-PI.017 doesn't send items to PL.
So...

First of all - big thank to you jwq - all your advices were very important and precious! :yes:

I've connected everything like you said and it's working like a champ :thumbup:
6 buttons from steering wheel is working.
All speakers play sound.
BOSE amp is working (yes, it's a little loud, but for me it's quite alright - my new headunit has 0-40 volume level, on 10 music is playing loud, on 20 very loud, on 1 it's almost silent, so there is no problem with Bose amp for me).
Bluetooth is working. The only thing is that I finally have used microphone from my headset instead of buid-in-car. All pins that you gave me is good (colors of cables in D connector and that connected to the microphone are the same), but I suppose that original microphone is too strong/weak/different/sth for my new headset. Or it's not working at all. Never mind. I've mount new one near speedometer. It looks not so bad.
Another thing is that I must use antenna connection converter (see below).

Nevertheless everything is very nice now, I'm happy that this is over :biglaugh:


One more thing. I've found n the Internet (see image below), that I must modify my CA-R-PI.017, changing cables layout in C connector socket.
I've tested connection without this modification and all buttons works fine. So - it's not necessary for me.

 

Totally 100% jealouse!

Might start seriously considering this in my GT to replace the OEM Blaupunkt unit...

Can you pop off the bezel at all to re-colour it to the match the original dash?

 

I'm glad to hear, that this is nice not only for me

I can take off only the external part of the bezel (you can see it on picture 4 of 7) and I was thinking about some repaint, but finally decide to stay with the black (after my non-pro repaint new color can be scratched or sth).
I didn't say before - I've chosen this model, except many other things, because it has red backlighted buttons - like other in GT, so it compose great.

 

I see...

Will keep a look out for a Pioneer unit like that at the right price... Had a lurking desire to fit a double DIN unit for a while, never really gave it much thought but it looks relatively easy to get it working with the steering wheel buttons and Bose system providing you follow all the knowledge here!

Now if only Pioneer did something similar but based on an Android OS and Google Maps native support....

 

Pioneer already has some models that support Android Auto

I'm currently installing an Appradio from Pioneer. It's a bit cheaper and with Appradio Unchained, you can have full Android on your 2din screen. But I was wondering if I could use the GPS pin from the ConnectNav. Since it's exactly the same pin used on the GPS module that comes with the Pioneer SPH-DA120

 

:thumbs:

 

Today I figured out that there is need to swap red and yellow power supply cables.
This provides some power for headunit functions when engine is off.
Without it on every start I must set language, date and time. Also the unit doesn't remember last audio source (radio/usb/bluetooth) or last playing song.
Easy solution, big difference :yes:
