Use Honda factory antenna on any radio

Easy way to connect your Honda factory antenna to a new aftermarket radio. There is a similar adapter that goes the other way (aftermarket antenna to Honda radio) so be sure to get the one you need.

If you're putting a new radio into you Honda using the factory antenna, this is a must-have adapter.

Antenna Adapter Works like a Charm

This adapter makes installation of an aftermarket car audio receiver go much easier and cleaner. I had a professional installer put it in, and there were no issues. My car is a 2011 Honda Civic and the receiver is a JVC DVD/Nav unit. The radio sounds great.

Works with Mazda too

Makes for an easy plug and play experience to get HD radio with an aftermarket head unit. Works perfectly in my 2014 Mazda 6. Great value for the money.

Just what I needed

Bought this antenna adapter due to the fact the after market stereo harness I got did not come with it. I know people use there phone more then radio but for road trips radio is always I good thing to have!
