Audi A3 8L - Concert Headunit Replacement?

[taffjohn]

Hello All,

I've recently purchased an Audi A3 1.9TDI Sport 03 Plate.

Would anybody be able to advise a replacement headunit for an Audi Concert?

Need to have the following:-

1. All 4 Speakers to work in Car, same as current Concert Unit

2. Bluetooth

3. CD

4. Dab, Depending on cost!

5. Display needs to be red to blend in with interior lighting.

Also, could any body confirm where i can buy a used Aerial Base (Amplified).

Thanks for your help
