I've had great success with a Dasaita unit in my FJ Cruiser and desided to get the QCM6125 for my 2020 1974 Edition Tundra. The install went well, all the more complex things work, however I have no rear or center channel audio. When looking over the wireing I notice the speaker cables in the harness doesn't seem to match up. There are only 3 pairs of cable from the truck going to the harness, the the colors don't seem like they would match up right anyway. The 1794 Edition does have the JBL sound system; 9 speakers and a sub. The left and right channel work, and the sub works.
My version details are as follows:
