I got it hooked up, everything seems to be working EXCEPT, the radio audio is missing the low end. I had this issue when I upgraded to the 2016/2017 Non-Navi radio, but when i moved the pins it worked.

Does anyone know where the issue is for the missing low end/bass and what I need to move to fix it. I've been looking at wiring diagrams.

Replied to your other post.

I don't believe the GPS antenna in the early models '13/'14 are compatible. Mine did not work. 1. Plugs are not the same, after swapping, it still did not work.
