I have a DVD90 Navi in Piano black color that is not working and I would like to buy a 2nd hand one to replace it on my Astra. Would it be possible, if I buy a Charcoal color one (that I can find in decent price), to change the front face with my Piano Black one to match my interior? Cheers.

I have gotten my hands on a DVD90 and want change the LED's but i can't get the select knob (the big one) of, I have tried to pull it off, like the CD30 without any luck. Is it possible? Or is there a nifty little trick?
