Swap out non-Nav for OEM Nav - Aux-in problem - Toyota Nation Forum : Toyota Car and Truck Forums

Hi All -

I swapped out my 6-disc in-dash JBL OEM system for a Toyota (Denso) OEM Nav system on my Camry Hybrid. To complete the task, I ordered the SW Aux Wire Harness from a dealer in Canada (US dealers aren't familiar with this process yet). Even with this part installed, I can't get the Aux-In jack to work (it was working before with the non-Nav JBL system).

For some reason, the number of wires on the harness (4) is different than the number of wires coming off the Aux-In jack (5). I can post pictures demonstrating this difference tomorrow night when I get home.

I'm wondering if anyone else here has done this swap and has been able to get their Aux-In jack working with the Nav unit. If so, which part did you order to connect up?

Thanks!

I have no experience with this problem but get your handy dandy volt meter out and do a little checking on that 5th wire. see if it is a ground wire or if it's hot all the time, or when something is turned on or when a button is pushed. Hopefully it will igive you some insiight into that is is suppoed to do.

Thanks, gfanaher, that's not a bad idea. I don't own a volt meter (yet) and even if I did I'm not sure I'd know which wires correspond to which once they get through all the harnesses. By way of illustration, here's the set-up:

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). These wired disappear into the mass of wires all bound together, then somehow emerge into a single harness, which then goes into the Y-harness above.

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.

I'm just curious if anyone knows anything about this.

Thanks!

F17 connector into the Aux In Jack should be Grey, with Brown, Red & 2 Green wires. I do not have your nice JBL (type) system, looking at the wiring prints, F17 is the same for both units [W/Wo Nav]. Check around behind the storage compartment for the stray Grey connector. The "Y" adapter appears to be wired right. (Best guess, couldn't count all the pins... Great Pix's!!!!)

You might have found a connector that should be on something else, and the two got swapped. {Check the back of the Hazard Warning Switch. Just a guess....}

GOOD LUCK!!!!

HI Luna -

Thanks for the response. I went down and pulled the storage compartment and hunted around for a while, and couldn't find anything like what you describe. I believe this is what you mean, in the image below (from another person's DIY guide to backup camera install):

Correct?

Mine isn't that one at all.

I'm beginning to think something changed between the 2007 and 2008 models.

Give the Emergency Flasher switch a test, if it works, that will be eliminated. If it don't, Bingo.

toutsuite · 05-27-2008, 06:24 PM

The flasher does work. I found this out, unfortunately enough, yesterday following a fender bender.

Besides, I can't imagine that harness reaching all the way down to the storage compartment.

Correct on the E plug.

I think I found it. It could be "e1"... This should plug into the AC panel on the side next to the driver. I will bet the Aux Input connector is in its place.

The Aux Input has only 4 pins and 4 positions. The one in the last Pix has 5 wires and 8 positions.

Odds are the Air Inlet, Air Vent Damper, Air Mix Driver Side, & Air Mix passenger side servos are not working.

Hope this is IT..........

Another good thought, Luna. Are you talking about the gray plug that plugs into the back of the HVAC unit, right under the nav unit? That one is a different size than the one currently plugged into the Aux input, and had 8 wires plugged into it.

All my AC controls seem to be working correctly, as far as I can tell.

Also, I took the time to write down the part number of the Aux Input jack itself (called "stereo jack" by Toyota): 86190-02020

I can't find any reference to this part online at all. I've found other "89160" parts in reference to the Prius stereo jack. If anyone has a chance, can they pull out their storage compartment and check the part number on the jack, and also the number of wires coming out of it?

Thanks!

I don't have any listings for the components, just the connectors. The servos, control the "MIX" of the air, probably won't feel much change till the car is hot, turn on the AC and vary the temp setting. The wire colors aren't listed on the prints, this harness is a separate assembly that splits into 5 more connectors to the servos for the air mix doors and the A/C Evaporator Temperature sensor.

This was the only connector with the right number of wires and positions that matched the photo and was in this area. I figured it had to be removed to change the head unit and was swapped buy mistake. A small mirror could confirm. "This is still a best guess." GOOD LUCK>>>>>>

There's only one connector attached to the HVAC unit, which is a different size and shape than the one which fits in the Aux In jack. I think the right connector is attached to the jack, I just think it's changed for some reason since 2007.

Thanks again for all the suggestions.

Is anyone here planning on installing a Vais unit or for any other reason pulling their storage compartment out? If so, can you check the model number on the jack?

Thanks!
