swapping 2003 radio to 2002 tahoe

I am new to this forum and a new 2002 chevy tahoe owner. I would like to buy the 2003 tahoe navigation radio and install it in my 2002 tahoe. Is this possible and if so is it fairly easy to do.

Anything is possible if you have the time, money, and know how. But I dont see why you couldnt do it. Check the connections on the back of each radio and see if they are the same. If they are its just plug and play. If they are different go to Best Buy or Circuit City and get an adapter, then it will be plug and play.
