Replacing 2001 GC aftermarket stereo

I'd like to replace my Blaupunkt (or Blaujunk) stereo with another one. The lights stopped working within a year unless it's really cold. How easy is it to replace a stereo? Since it's already afteramarket, I assume the correct wiring has been installed. Should just be a matter of removing the trim, headunit, and putting in the new unit. Am I missing anything?

Go to www.crutchfield.com , they have a great selection and they will give you very detailed instructions on how to install for free along with the required adaptors that should just plug into the car wiring assuming whoever did the first job did not cut and splice the factory wiring .
