Hi all
'Im new to this so go easy on me.
I recently brought a genuine audi satnav plus to fit to my 2004 S4 cab. I fitted the satnav to find that it wont let me enter the code. The place where I brought it from told me to change the safe wire so it has a permanent live. The head unit itself also is permanently live and doesn't turn on and off with the key. Can anyone help with these problems or advise on an adapter wiring loom I can buy
