Radio Wires

[ZerokoolRCZ]

Hi, hope someone can help?
what to change the radio in my 2013 RCZ, have bought all the cables I need, but am having trouble identifying some cables, as you can see in the photo, have a white and grey cable (both say VW AUDI)I think the white is the aerial but don’t know about the grey one? Any thoughts

I think they are both aerials, the unit picks from the strongest signal. There is a little info online if you search for twin (or double) fakra.
