I would like to wire up an amp to my cdr 2005 head unit in my car. I have been unable to find any wiring diagrams or installation instructions for this head unit. Firstly, will I be able to safely attach an amp to this unit?
Secondly, how do I remove the unit without damaging the surrounding brackets? I have tried removing the grub screws, but the unit is still securely fixed into the dash. Are there special keys I need, would I be able to use the keys from another head unit to do this?

Best thing to do is take it to your local car audio place, I had the same issue as there are lots of different styles of 'keys' out there to remove the radio, and in my experience none of them work (having removed the grub screws).
My local car audio store charged me a fiver to get the radio out. (There seems to be a nack to it). Sorted.
