2004 Honda Accord LX radio swap?

I have the factory radio currently installed in my car. I want to remove the radio with an aftermarket one but can't because when I pull out the radio the AC/Heat controls come out with it. What is a cheap solution to keeping my climate controls and changing the radio?

*I haven't bought the aftermarket radio, yet. So, if there's a certain radio that works better than another then please let me know about it.

The radio and the AC/ Heat control panel comes off a a whole unit but the radio can be separated from the frame by removing the mounting screws. Then you can update the radio with after market unit either with a radio or Nav or anything else.

The following video will show you how to remove it:
