What seems to be the prob.
It can be a pain fitting a new head unit,
Can also leed to a power drain on your batery if not spot on, may need a pro mate?

You don't have a switched live, you need to feed in another live.

Sounds good but no clue how to do it.
Is it easy? How long it may take.
And a short advice how to do it please if you can.

IIRC I took a live feed from the other live feed. Where normally you'd have a live and a switched live. You'd have 2 lives, so you'd have to remember to turn off the cd player.
I hated this, so if you take off the steering wheel lower cover. There is a very thin red wire, this is a switched live and it turns off when you take the key out of the ignition.
You run a wire from this to a relay, this turns the relay on. Allowing a better feed of power to flow into the switched live feed of the radio.

Thanks for your help so far.
Where does the live switched needs to go to?
Here is a picture of wire loom of the unit:

If you can help me with that please.
