"FAKRA VW Antenne RadioADAPTER RCD510 RNS510 RNS RCD MFD"

This is an Y adapter that goes on the back of the Columbus. Can anyone please tell me what this is used for, Is this something i need on a rns in a 06 Octy with only one antenna?

Are you fitting the columbus if so then you may do

I already have one, but get all these faultcodes on open circuit on radio antenna. I'm not impressed by the radio reception either, so I was thinking this might help(if it fits).

That'll fix the OC errors and should improved reception too - if you check the Groups Buy section on here that'll point you to another version...

Have you bought one yet?

I'm thinking of running a group buy.

Yes, actually I had already bought it when I posted this. Started thinking afterwards about if I needed it.
