Ok Here is what happened.
I had a 86120-0C270 in my 2010 double cab. Mine is a 2010 but it was manufactured in the middle of 2009, my truck only has the AUX port no USB, so take this for what it is. I recently found a 86120-0C290 on eBay for cheap and purchased it. After researching, I was worried that the auxiliary port would not work. I came to terms i would have to install some adapter later and proceeded with the install.
after pulling the old radio out, I test fitted and checked the operation of the new one. Radio worked, good lets proceed. With the A/C controls laying in the floor still all plugged up, I plugged in my phone to the aux and hit the aux button on the new unit. Bluetooth popped up which I did not have. Great I thought, adapter it is. Then I went to test the CD and realized I had left my Skynyrd cd in the old unit, crap. New unit came out old unit went in, eject cd. Then I took the plug out of the back of the aux port to examine the wire coloring. Im pretty sure these wires run to the 20 pin on the back of the old and new stereo.
I stuck the new unit in, finagled the dash back together and started setting the presets and along with other settings. Skynyrd played just fine, so i decided i'd give the aux port one more shot. i plugged the headphone cord into the stereo and an aux light came on the screen, ALRIGHT!! Plugged my phone and and it worked just like it did with the old unit.
Don't know what i did, if the plugging and unplugging of the port helped, hell it coulda been Skynyrd's doing. I do have pictures of the wires if it will help anyone.
