New here!

I just purchased a 2008 Civic LX for my daily driver. I want to replace the factory radio with an AM/FM/XM Honda Civic Radio. I plan to get one from internet sales, probably used. Any good sources?

Question: When I get the replacement, is it simple "plug and play" or do I need to get a special wiring harness? Is there a DIY post somewhere on this forum?

Thanks for any advice.

Also, please remember those who gave their lives so that freedom rings for the rest of us. Thanks to all the Vets.
