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.

2 questions already asked

Thanks for your question. Yes for your vehicle listed without navigation that is the correct adapter. [ Kenny  May 04, 2016 ]  Staff
blue wire connects to the aftermarkets radios' power antenna/ turn on lead. [ Charles  May 11, 2015 ]
Check the wiring harness for the main head unit- there should be a corresponding blue wire to power the antennae amplifier in the car. If not, this simply needs to be connected to a switched 12V out (e.g. the power amp 'on' wire). [ George  May 11, 2015 ]
It's for power, if you have a power extending antenna you would hook the blue wire to the power for the extension motor. [ Tommy  May 10, 2015 ]
For details on fit or installation please contact an Advisor by phone (1-800-324-9695) or online chat. They will be able to pull up your vehicle and give you the details on if this will fit and what you will need for an installation in your vehicle. [ Krissy  May 10, 2015 ]  Staff
