So, I copied the shopping list on the first post almost to a T--bought the new bigger dash, the harness, only exception is I bought a Clarion NX-404 for the head unit.
Got it all installed, it looks AMAZING. Turned the key to on for 30 secs to initialize whatever needed initialized like in the instructions, turned it off, then turned key back on and started the radio. Really happy with the looks of it....except.
There is absolutely NO sound. I triple checked the wire connections, made sure they were all going the right place. I didn't do any crap installation job either, I used the nice heat shrinkable butt splices and zip ties to keep it all neat and organized. The radio powers on, the GPS works, it accepts CD's, it switches to rearview camera mode when in reverse, the radio dims when I turn my lights on....it ALL works...except the sound. I have the two plugs in the back as seen in the pic.
This is the Factory Head Unit it had....
