Whats the radio model? What model car/year?

 

the sienna is a 2001 and the sound system is the oem jbl sounds system that came with the van. not sure of the model of the stereo. let me run and see if i can dig one up.

ok, the model is the toyota ad 6805 jbl stereo.

tks

These ones were the JBL headunits found in the 2001 JBL equipt camry. There's another 'look alike' model of this that is a multi-cd player one.

Does the Sienna have steering wheel controls? What kind of wire harness do you have?



Not sure if this helps, but on my JBL equipped 2004, I was able to use the Metra 70-8113 on my 2004 JBL Camry to get it working with my Pioneer double din w/ DVD. Your head unit must have atl ease 2 pairs of RCA pre-out though as you are by-passing the aftermarket head unit amp and using the JBL headunit instead. I match the 70-8113 harness to the after market headunit using the wiring diagram in the package and in the manual. You might have to refer online (I not sure where, but its plentiful) wiring diagram for the toyota wiring specs.

Something similar below, although this is using the Metra 70-8112 as it is older toyota model.

king, i am using a metra harness with the rca outs so it works fine. the only thing that i can't get is a handle on those darn steering wheel controls. it appears some are resistance based so would just run 12v to ground and a differential circuit would detect this and take an action based on the volt drop like volume up/down, etc.

But apparently toyota did something involving the ecu (can bus) on this model so it's a computer output i'm dealing with so not even sure i can add the wheel controls even though the aftermarket ownice c200 has key1 and key2 inputs.

I'm assuming that's what the yellow/black and red/black wires are that are leftover's in the oem harness i don't have matching wires for in the metra harness.

thanks guys for your help. my wife's just gonna have to use the controls on the new stereo.

So something like this won't work?

The radio on my red camry sounds fine with just the big antenna plugged in. Maybe there's a converter.

My cars that I worked on had two plugs. Just use the big one. Never had an issue, i think it was to boost the antenna signal...not like I use radio though.

 

The smaller antenna connection is for the in window antenna, if you have one.

 

thanks blue. my oem has jacks for both and both were plugged in but the aftermarket does not. will this break in the diversity hurt my radio reception? is there any way i could junction the two leads together using an impedance matching transformer or something or just the single antenna sufficient?

thanks king. i dunno how mixing the 2 without an amp or impendance/isolation transformer will work but i'll give the y adapter a try as I'm a big AM talk radio fan and don't want to lose that.
thanks guys.
