So I am having an issue upgrading my 2010 fit sport without navigation to a double din unit from soundstream.

So I am almost set but the Harness adapter needed I cannot find.

I have the 20 pin gray done with metra 70-1729. But I still need one to connect to the 2 white male ends 14 pin and am stuck here .those plug In what is circled in pic . Right now without those plugged in I only get sound from one speaker due to this Honda having split wiring for the speakers.

Any help is appreciated!!! 💗

 

The manufacturer of your replacement radio will make all the adaptors you need for your application. Call or communicate with the radio manufacturer OR the store you bought the radio from to find the adaptor you need.

 

Are you sure you don't have blown or disconnected speakers? I put a new HU in my 2013 Sport that didn't come w Nav using the Crutchfield kit (https://www.crutchfield.com/p_249HN6...Interface.html), which only has an adapter that is similar to the Metra harness, and it worked fine.
