Need Help: '03 Mitsubishi Outlander stereo replacement
 

Hey guys, I'm new here and searched around a bit so if I missed this somewhere else, I'm sorry.

I am trying to upgrade the OEM Infinity stereo in my daughter's '03 Outlander to a new unit with bluetooth and SD card capabilities. I first tried with a Pioneer unit, and then when unsuccessful I tried with a double-din Ezonetronics unit. In both cases I "thought" I had everything correct, and the unit powers up, but I get no sound.

After 3 days, I'm looking for any sort of help. I've tried a straight wiring harness where I just matched up all the wires, and I also tried a metra harness that had the "plug" or whatever that is called as well. Either way, I am clearly doing something wrong but I have no idea what it is.

Any help would be GREATLY appreciated. I'll be checking frequently to answer any follow-up questions. Thanks!
