What tool(s) are needed to remove the radio headunit out from the dash?? and where do i find it? Thanks

 

I don't recall any special tools. Just a philips screwdriver, mostly to get the bezel off.
Two screws in the cubby hole (in the top edge of the opening).
Then pull off the heat control knobs and remove the two screws found there.
The the bezel pops off. It's held by some clips.

The screws that hold the radio are now exposed.
I thought they were also philips, but they might be hex head (probably 10mm, like everything else).

 

Sometimes the knobs may not come out when you pull on it with your hand. Be careful and don't break it.

Put a towel over the knob and use a pair of pliers to pull it off. Be careful and don't scratch anything. For more reference, search for radio relation in the Lancer How To forum
