I now understand.
The Becker Grand Prix C connector pinout is different from the original Becker-made Porsche head units. The original M490 Hi-Fi connector pinout is given in the Nokia Hi-Fi amp pic above in this thread, and was of course a plug-in solution to the Porsche units.

If your GP is connected to the existing M490 amp without an adapter, the wiring has been altered in order to fit to the Grand Prix pinout.
Cheers,

What a bunch of crazy :grin: you would have thought the pin out for these connectors would have been standardised across all brands. Glad we got to understand a little more :thumbs:

Just need to see if I can find a way of increasing the signal between the phone and the amp now. Thinking something like this may do the trick https://www.amazon.co.uk/Level-Boos...coding=UTF8&psc=1&refRID=HMZBPSJQ40V66QT8CWFA

But also thinking that this is all getting a bit complicated and might revert back to my original idea of replacing the Nokia amp with the kenwood amp with built in blue tooth, but then I will need to add cross overs for the front speakers. :frustrated:
 
Resurrecting this post again another year later :)

Did you manage to get anywhere with the idea of not having a headunit in the car but controlling all music and communications via an iPhone? Whether via BT or cabled?
