My radio signal is rubbish

[Jamesey]

That one doesn't get used on UK cars

Wonder what it's for though....looks like I need to look at the white wire then for the aerial power then mate

I've got a rouge brown and grey connector just hanging around next to my live side iso connector any idea what this is

For some radios you need an inline amplifier as well as the working amplifier in the aerial.

There's a good thread on replacement options here: https://www.s2forum.com/forum/techni...pe-roof-aerial

I ended up with a Calearo ANC7677932 which is the correct angle and fits into the roof property with OEM equivalent seals and also has DAB. Reception is great.

It was fine until I unplugged it and messed trying to fit a ignition feed but then put it back and now it just crackles on local stations as though the aerial isn't connected at all

I replaced the amplified base on mine years ago and the radio reception was still rubbish.

Me too

Thanks mate .
Mines only got 4 wires on the live iso plug ...1 permanent live , earth , white wire and a very thin brown

To get the radio to work with the 4 wire ISO you have to connect both constant and switched from the radio to the 12v on the ISO

Or if the radio is ISO then bridge A4 and A7

That’s correct. There’s a thin red on the back of the ignition switch that’s stays on till you pull the key.

Anyway, take the switched power out from the radio and connect it to the white to power the aerial

Audi have never had an ignition feed to the radio on these cars. It's battery 12v only via fuse 4.

[Bowie69]

You'll want antenna, funnily enough.

[Jamesey]

out of that lot you'll have blue/white for speed signal, blue/red for 12v, grey/blue for illumination, white for antenna, brown for earth

I'll get some shots later , definitely no ignition feed.

Does your car still have its ISO connectors?

A5 goes live when radio is switched on. I *think* it’s a white wire in the car but not sure.
