Review on SWTNVIN Multimedia 2006 2011 Navigation Bluetooth by Donnie Boss

Good sound quality!. This is much better than Kunfine or Lexxon canbus decoders which made a hissing noise. I had to remove two zip ties to allow the connectors to reach both sides of the decoder box, the wires could be longer. There are no instructions. On my main Swntin device, I had to go to the Autoinfo app (weird place) and click AMP. Autotune worked fine for me. It was in manual mode with the amp set to 0 from the factory lol. It took me a long time to figure out why I was messing around with the volume buttons and RCA jacks but never heard anything from my Sonata lol.
