Help advice needed i have CD30 MP3, want to upgrade touch and connect or similar

[corsaLil]

Hi all,
I have a 2012 corsa d se spec, i have removed my cd30 mp3 to see what i have on rear wiring loom

On small connector block i have:
Aux L
Aux R
Aux Ground

PH +
PH -

Is PH + & - for phone mic loom? As on diagram ( below) it goes to a control unit pin 34 and 40? i have the 3 interior light with mic but no mic in there?

All i want is a factory bluetooth for handsfree with either my current set up or Touch and Connect

Here's a pic of radio i have circled in yellow what wires in car loom i do not have
What would be easiest for factory oem ? does my current support Bluetooth handfree mic OEM or Touch and connect the way to go??

Ive made this diagram up so its look like you will have to live without USB no biggy
And what is speed signal in Block C pin 37...?
