Blue&Me and MiniIso splitters. Its all backwards!

[kEvo95]

Hi all,
here's the predictable bit... I want to take a line-out feed from the HU so I can run to an amp+sub.
So I've had a look around the rear of the original HU in my Punto Evo with Blue&Me + USB to see what's what. The C1/Yellow block is already used so I unplugged it to see what happens:
- Blue&Me still powers up + phone connects
- Media player works and starts playing some music off the USB
- NO AUDIO!!!

How can I have full functionality but no audio if the C1 block is meant to be for HU line-outs?!? Have FIAT+Blaupunkt somehow turned this into a HU input?? Why isnt C3 Line-Ins used? Is it all back to front or am I just being an idiot...be honest :bang:

On closer inspection it seems only the Rear Left+Right and Ground is actually connected for the Blu&Me feed so my plan is to make up a Y-adapter so I can leave Blu&me plugged in and tap into the Front Left+Right and +12 switch...I guess we'll see what happens...

Ignore the mini iso. The only part that works as an output is the romote pin.
If you want to add a sub and amp to the oe system you have to use a line level converter and tap into the speaker wires.
