There is one wire in the harness that goes to the radio that carries the
steering wheel signal. If the radio you buy has a remote input pin you
might be able to simply plug it in. More likely you will need an adapter to
convert the Honda signals to whatever the radio wants.. Your local sterio
shop should be able to tell you what you need basid on what radio you get.
I put an Eclipse in-dash nav/dvd player in my 2006 CR-V. It only accepts IR
remote input, no wires. The adapter for the steering wheel controls has a
little IR transmitter that we mounted next to the unit.
