Re: Non-Nav swapped out to Nav, Aux-In problem
Hi SPL -
Thanks for the reply and diagrams!
Unfortunately, I think they're for the 2007 Camry, or at least the previous iteration than mine. These show four wires coming from the stereo jack (green, green, brown, red). It seems this has changed in later models (such as mine) to a five-wire connection from the stereo jack, as seen in my images above.
Further evidence is provided in a new TSB from Toyota to fix audio hiss and static from the stereo jack with a new filter and wiring harness which shows five wires coming from the stereo jack, in the same configuration as mine (see attached PDF). I think Toyota switched to this configuration as standard to try and eliminate the noise problem.
So, I think the problem has to do with the Y-harness I ordered to fit for the Nav unit. I can't say for sure, but I think this was made for the old, 4-wire connection from the stereo jack, not the new five-wire one. Either Toyota has updated the Y-harness, or I'll have to figure out where that fifth wire is going and make sure it gets to the right place?
