I'm having difficulty with the 'memory' on my headunit. At the moment when the keys off, the unit is off and resets when the key is turned on. Works just fine with the key on.

I have +12V across Black and Red (sticking the probes into the back of the plug while it's in the radio) at all times, and +12V across yellow and black when the key is on.

The only other wire is the blue, which the manual says is for power aerial - which i don't have so have left unconnected. Any ideas?!

Probably unrelated, there are two car wires not hooked into the radio - a 3V and 12V line that are only on when the lights are on. These are just taped off. 

I'm pretty confused as it appears so simple!?

Go the Warehouse.

Yellow is pretty much always a permanent 12v connection for memory/clock in the world of headunits.
Make sure its fused! (Only a little tiny fuse required for this wire).
