Great adapter for aftermarket radios

Not a lot to say. This little adapter plugs into Honda's proprietary antenna connector and converts it to standard antenna connection for your aftermarket radio. Plug each end in and your done!

Pros: Easy as pie.

Cons: None

Crutchfield Customer Review (What's this?)

This was the one part from the system that did not fit. Not sure it was the right car model but I went and bought the right one and it worked fine.
