I'm not familiar with the Accent... On the Elantra you have to take off the whole dash fascia which sounds scary, but it's really a lot easier than it sounds. I say go for it. If you have any more specific instructions for doing it, seiken, that would be helpful (is there a certain way to pull the bezel off to make sure it won't break... that sort of thing).
Also, I did a writeup for the Elantra over on Edmunds. Some of the stuff, like the wiring and how to hook up the adapter harness, should help with an Accent install. Here's a link ot that: http://www.carspace.com/guides/2001-...ra-Audio-Guide
