The outcome you require is quite simple, if you are not confident read my thread..Do you mean take a front panel off of another radio. Is that easy to do. I would of thought it was lots of solder and wires to undo which is way beyond my capabilities.
It's the concert single din with cassette slot.As your buttons are good remove the board from the replacement front panel and fix that to your fascia with its good buttons, then refit to the radio.
If you have an early car make sure you have the code for the radio before you disconnect it from the car as you will need it when you reconnect the radio. Later cars you do not need the code provided the same radio is reconnected.
Which radio is fitted currently in the car?
