Mysterious antenna

[gruf]

I have a b6 cabriolet which had the old sat nav with TV tuner,
I've put the rns-e in and have a spare aerial.
Also can anyone tell me what the other terminal next to the aerial input is on the back of the rns so if your look at the stereo from the back it's the right input of the blue double connector.
The connector on the right is the one I'm trying to work out what it's for.
Thanks

Can anyone help

If it's like the Avant, then they have 2 aerials, look up "diversity aerials" it will explain things

Sort of. Any clues on the right socket on the back of rns the radio fitter said it was an output as he tested it on the voltmeter but I'd rather know what it's for and if anyone can explain what I do with this 3rd connector the one on the right. Thanks

Prob diversity antennas and / or one isn't the GPS antenna is it ?

The connection in picture one from let to right are 1. FM 2. GPS. 3. ?
The FM Aerial connects to the left of the double connector the GPS goes in the top right corner.
I'm thinking the last wire and right connection is to do the diversity. I've searched flebay and found this. http://pages.ebay.com/link/?nav=item.view&alt=web&id=371310788063&globalID=EBAY-GB
Is this the misery connector?
Thanks
