Hi All -

I swapped out my in-dash JBL 6-CD changer for the Toyota OEM Nav unit, following the advice of DanG from this forum. Everything went very smoothly, with one exception. I can't get the Aux-In jack to work. On the 6CD unit, it worked perfectly, but that only required the cable coming from the car's wire cluster to be plugged into the back of the unit. The Nav requires a Y-cable to split this harness into two, and this is where I believe the problem lies.


This is the Y-cable which bridges from the car's harness to the Nav unit.



This is a close-up of the Aux-In part of the jack, which plugs into the nav head unit. As you can see, there are four wires leading in (red, green, pink/blue, and black).


And this is the cable which plugs into the Aux-In jack itself, at the back of the storago compartment. As you can see, there are five wires leading out of this (red, black, white, green, and orange).

It's this four vs. five wire discrepancy that makes me wonder if the Y-harness is the reason I can't get the Aux-In jack to work. I purchased the harness from a Canadian Toyota dealership, as those in the US aren't familiar with the part as no one down here is swapping in navs as they are up there.

Anyone else done this swap and gotten the Aux-In to work?

Thanks!
