2009 Honda Civic Aftermarket Stereo?

[Icebonez]

Sorry guys if I'm posting this in the wrong section but I've been trying to figure this out for a while and i figured I'd ask the awesome tech guys on this website. So I recently received a 2009 Honda Civic from my grandfather. The car is slightly used with only about 20,000 miles on it. Now I'm looking to install a new radio in because aftermarkets tend to have a lot more features in such. Is it possible to install an aftermarket radio inside the car? And if so, can anyone give me some options with high quality radios that are compatible with my car? If you guys can give me as much help as possible with this i would really appreciate it. Thanks everyone!

http://www.crutchfield.com/ will have retrofit kits and harnesses required for making things like steering wheel controls work with an aftermarket headunit.

Yes, is it single or a double DIN unit. almost any car can take almost any car stereo - and you can get them fitted for you at most stores
