..Get the radio code before disconnecting the negative terminal on the battery, or do you only need it if you disconnect the live aswell??

On the MK4, you'll need it if you disconnect either.

Cheers for that Mr. Oracle

And is there anything else i need to do or not do before i disconnect it??

cant say as ive ever disconnected the battery when doing a radio lol nothings ever gone wrong either, does this mean you have an r32 now?

Taken the battery out of my MK4 completely and the Radio (Gamma) worked fine afterwards. Didn't ask for a code.

Mine always asks for the code. Even if the battery goes flat
