yeah man it's pretty easy to do, but it will be a pain to take the old one out. personally i don't like the autoamtic antenas on the accords. they are so tall. i repl;aced mine with a universal fit antena for $10, and the reception is better. all you need to do is rebove the old antenna, by breaking the upper cap, and unplug the 2 wires behind the trunk liner. then if i remeber well there are 2 screws holding the antenna up. after removing those two the antena should come out. put the new antenna in, and you might have to cut the antenna wire and tap into the old wire. it's pretty straight forward.
and the fanatism: read my name
