Installation was fairly easy. I have a 2002 Honda Accord, and this 2005 Honda Civic stock radio was compatible with my vehicle. I removed the original Honda Accord stock radio, and replaced it with this one. I now have MP3 playback capabilities, and an auxiliary-in jack to plug my iPod into. The radio harness is the exactly the same for most Honda models between 1998 to 2005. I simply plugged the radio harness into this new radio, and it works perfectly.

The only downside was that I lost the function of the steering wheel control buttons. There is a known issue with signal irregularities between the steering wheel control and the radio itself that can affect certain Hondas. This newer Honda Civic radio does not communicate properly with the steering wheel controls on my Honda Accord. This would cause the radio to receive a \"fake\" signal from the steering wheel control buttons, causing the radio to switch between CD and AM/FM back and forth, while no actual button is being pressed. To disable this, I simply cut the wire that connects the steering wheel control buttons to the radio. The corresponding wire is a green/red wire located at pin 3 on the harness. Now that the wire is cut, I no longer have the signal irregularity causing the radio to switch between CD and AM/FM. Losing the function of the steering wheel control buttons is a small price to pay to have such an awesome radio installed in my car.

If anyone has questions on how to install this radio, don\'t hesitate to ask me.

Reply by Replacement Radios on 1/27/15: It is a signal irregularity problem but it is not a compatibility issue. The signal problems are caused by the way Honda installs their steering wheel control harnesses. They get worn in places, allowing contact where it should not be made, resulting in irregular and unintended signals. As indicated in the ad, if you are one of the unlucky ones to be bit by this problem, you can either have your steering wheel control harness replaced (expensive) or cut the steering wheel control wire where it goes into the radio (cheap.) Obviously the second method means you lose your steering wheel controls, so you would need to determine which is more important to you, the radio or the steering wheel controls. FYI - We only have this issue reported in about 1 out of every 10 sales.
