I purchased a Seat Satnav and got about installing it in my car, only to realise that I didn't have the GPS aerial. I had a look at the back of the unit, and this is what I could see...

(Ignore the little black wire - needs removing, as it's connected to nothing)
As you can see, I have an aerial connector, but I don't have a secondary connector like the pic below. I have looked at several other VW/Skoda MFD satnav systems and most came with a second connector, like this...

I had a google and I read somewhere that on the later models, they removed this second connector to save room and that I would possibly need a fakra aerial adaptor. I have also noticed that there is a little connector behind that black bit (top right corner). Could that be the connector I would use?
Now question is that if I used a fakra adaptor to wire in a GPS aerial, what do I do to still pick up the radio?

Or is there a way I can get an adaptor off the aerial connector that splits in two, allowing for the radio aerial and the fakra adaptor to both be plugged in?
This is the unit I'm referring to


Any help would be appreciated
