Here's a thread where someone experienced a tough time getting the radio out.

I was just about to warn you about having the code before removing the radio.
If you haven't heard these radios, they don't sound all that great. I too like the look of the OE unit versus aftermarket single din units. I removed mine to add the rear speaker kit which helped. I do like the look of the double din units. There's a great kit you can buy to make the DD look like an OE installation.
