Hello.
First of all, I searched info about my question in the forums, but I have no find the needed info.

I have a 2012 R300 BE with a command NTG2.5 system. This system includes linguatronic (I didn't use it), built-in CD/DVD Changer, Hard disc Drive, and an IPOD cable (old apple 30 pins connector) in the "glove box". This cable seems to be original and I connect it to an old 64Gb IPOD with "old" music, but I want to stream HQ audio to the system from my actual iphone (with Spotify) and I tried this:

LITTLE BLUETOOTH ADAPTER

I bought it and connect to the 30PIN IPOD adapter... but... don't work at all. NTG2.5 don't recognize it.

Searching on Aliexpress I found this adapter:

BLUETOOTH ADAPTER TO HARNESS

And seller says it will work, but I doubt it....
I don't know if this harness will use the white connector block you can see in the pictures that maybe it's actually used in my system and with this harness I will loose any actual feature...
Another thing I suspect is that this adapter uses somekind of simple AUX input, so I will not use the FF or RW buttons and can't see the songs titles in the headunit screen (as I do now with the old IPOD and the 30 pins cable).

Finally I found this adapter on eBay that seems to be what I need, but I found it EXPENSIVE:

VOCOMO Bluetooth Adapter

Do anyone find any way to stream audio integrated in the head (with controls and songs names in the head unit like I do with the iphone?

This is another posibility I found but seller don't answer my questions...

ADAPTER BLUETOOTH CABLE:

This cable seems to be the same where the actual IPOD cable is connected inside the glovebox. Anyone tryed it?

Thanks everybody and sorry about my "english".

Regards from Spain.
