Hey Guest👍👎 We're looking for reviews of your local CUPRA or SEAT Dealership - it's quick and easy to do: Leave a review now
heres the diagram from my original sat-nav unit i removed.
Its saying then that the grey\white connector thats 2nd in on the black connector is K-BUS ?

Ok it's not that one mate.
what colour is number 14 looks like a capital Y with a bit sticking up the middle.?

see thats the interesting thing, number 14 looks like the Y for aerial, except its blank theres no wire patched in to it ?. Radio all worked perfect on the old unit though.
You need to see what colour it is under the aerial base then, the trim pulls down easily it's tight but will pop off.
Then you can get the colour for the amplifier.

was going to suggest the switch in the line out section but iirc that was a yellow connector for rear headphones
check both sides of the connector too just in case it changes

yes thats what i was thinking, cause i dont know what colour wire iam looking for. Will the aerial just have one cable comming from it then ?
Will have the coax for the radio and a wire for the amp, as above check to see if it changes before/after the connector.
you cant see what colour it is from the aerial cause it has like black protecting cover over the cabling 
No choice now, but to get a circuit tester disconnect it from the aerial and try each wire.
Or get a booster lol

mate i might just get one of them boosters and be done with it, lol. The Autoleads boosters have a blue wire coming off them, where does does that wire up to ?
12v with ignition tbh is the easy way out
yep, atleast i know where that cable is. Just wanted to say a big thanks for all your help, ive learnt alittle bit more about seat stereo wiring tonight. I take it then this PC5-52 aerial booster will just override the one built in to the bee-sting ?
No problems mate
Yeah just goes in between your aerial connector and the headunit, then 12v+ easy.

Thnaks again mate, i'll update in the morning if i managed to get the booster and it all works.
There are potentially three aerial connections, GPS, telephone and radio (two if you have no telephone equipment). Which one are you connecting to your head unit? The radio aerial would have been connected to the lower section of the old double-DIN unit, the GPS aerial to the top section.
Both the GPS aerial and the radio aerial have amplifiers integrated into the aerial base. If left unpowered they may block out any signal from getting through.
The aerial leads are characteristic, coax leads thicker than the other electrical connections, needing a coax plug, two contacts.
There are no other connections to the aerial unit. I am forced to conclude that the aerial amplifiers are powered through the aerial wire.
The separate 26-pin connector is for the navigation system sensors, and contains no aerial connections, despite the indication on the diagram posted earlier.

Connections to the black connection block are listed as
1 - blue/white - Gala (Volume adaptation)
2 - green/grey - Mute (telephone)
3 - grey/white - Self-diagnosis / cable K
4 - yellow/red - Connector for the ignition and switch off with the ignition key (contact S)
5 - red/white - Anti-theft security system control signal, SAFE
6 - grey/blue - Lighting (terminal 58b)
7 - red/white - Battery + (terminal 30)
8 - brown - Battery - (terminal 31)
Connector layout:

Aerials have their own separate individual coaxial connectors, circular with a pin in the middle.
Cross-checking against the diagrams for the Aura and Brisa radios, they show pin 5 on the black connector as "Electrically amplified roof aerial control positive". However, from the wiring diagrams that appears to be parallel with pin 7, in other words a power feed to the radio, not from it. Still, thats the best I can find.
