I know this sounds like a crazy question, but will a Z1 interface with a 2007 Toyota Sequoia factory installed GPS antenna and/or Rear Parking camera?

Even if the connectors are different, if Z1 capatible connectors were used, would it then work?

Toyota called me tonight and told me they could not get the model we ordered (after waiting 2 out of the 3 months they told me it would take). They are attempting to negotiate a 'deal' on a higher end model with a Toyota Nav system with the PSD3 option for a Park Pilot, Rear Parking Aid SYstem (which I assume is their camera). I now have a brand new Z1 and XM module sitting in the box waiting for its new home!

No to my experience they don't like each other. However the Eclipse double dins drop right in. Probably has something to do with Fujistu Ten owning eclipse and Toyota.

Please clarify.

Are you saying the Z1 will not fit into the slot where the Toyota Nav system was? I thought it was all double din.

Or are you saying the factory antenna will not work with a Z1?

I doubt the factory antenna will work with the Z1, but its possible the rear camera might.

Factory gps antenna don't work with z1. Back up camera don't work with z1.

I got my Sequoia today. Started the install and the Harness does not fit with the stock radio harness.

I called metra and they said try 70-1761. It didn't work either. I described the connectors to them and they said they probably don't have a wiring harness.

Some questions:

1. Any one know if there is a wiring harness I can buy - don't want to hardwire if possible. IF so, what is the make and P/N.

2. The stock system is a JBL 6 speaker system. It looks like the Z1 has only 4 speaker outputs. THere is not an amplifier in the system that I know of (the TYTO-01 doesn't interface either). How do the installers handle this 4 to 6 speaker conversion?

3. Where can I get just the radio harness wiring diagram for the 2007 Sequoia in case I have to HARD WIRE!? Yuk!

After doing some web searches I've come across Metra 70-8113. Does anyone know if that would work?

Radio 12v blue/yellow + radio harness

Radio Ground brown - radio harness

Radio Ignition gray + radio harness

Radio Illumination green + radio harness

Factory Amp Turn-on N/A

Power Antenna black/red + radio harness

LF Speaker +/- pink - purple +,- radio harness or amplifier

RF Speaker +/- lt. green - blue +,- radio harness or amplifier

LR Speaker +/- black - yellow +,- radio harness or amplifier

RR Speaker +/- red - white +,- radio harness or amplifier

If equipped, the amplifier is in the center console, towards the front.

the extra speakers are tweeters, they are in line with the others

You'll need a toyo-1 interface. The radio have the jbl logo on it? If so that's the only way you're getting sound without running speaker wire to each speaker or the amp location.

Yes it says JBL.

Called the installer at our local Circuit City. He stated he used the 70-8113 in his last 2007 Sequoia install with JBL and it worked with the amp.

I don't know. I ordered one anyway. If it doesn't work, may have to get the TOYO-1 again (I returned it) and hard wire.

At this point, my install is being divided up into many little pieces with the final piece being the final connection to the amp with whatever works.

Where do you pick up the steering wheel controls for the SW1?

Misfit, do you mean by 'N/A' after the Factory Amp Turn-on as being Not Available or something else?

Thanks!

yes

1. If it has an AMP, shouldn't there be a turn-on wire?

2. Also, I had gotten from this forum that the Reverse wire (I'm assuming the wire going to the reverse lights to the rear) was Red/Black + driver kick, in harness going to the rear.

I found behind the driver kick two harnesses running in the tray under the plastic door threshold. There was not a Red/Black in either one of those wiring bundles. I took off the reverse lighting assembly in the back, and the wire to the light is red/blue (or red/purple, not sure).

I found that same wire in one of the bundles traveling to the rear behind the kick panel, but it is not 0V in Park, and does not toggle to 12V in Reverse.

Can someone clarify this for me!?

THanks for all the help, I really appreciate it. I am making progress (got both antennas installed, XM module mounted, and Speed Sense wire tapped into the green/orange wire in the ECM (behind the glove box, 2nd plug from right - info supplied by cntrylvr79 - much thanks!).

1. If it has an AMP, shouldn't there be a turn-on wire?

Nope Like GM and Chrysler, Toyota is started using a digital signal for amp turn on.

To the rest I really can say since I've not done a new sequioa yet. All I can say is that if you found the wire at the tail light might was well tap there.

I'm a little embarrased that I'm having so much trouble with something this simple!!!!

I ohmed out the + side of the rear backup lights and traced it to the Red/Blue (or RED/Purple, can't tell) wire. It's the correct wire. I believe it is Red/Black going into the connector interface and then Red/Blue coming out.

Anyway, I read 0V in Park and 0V in Reverse, even though the light comes on when I place it in reverse.

Perhaps that is because the light is a virtual ground with elements (although I would think it would have a little resistance). Anyway, if the Z1 is looking for a 0 to 12V logic signal, how is this going to work! Is it a current source trip and not a 12V digital trip?

In the mean time, I'm going to connect the reverse wire to this Red/Blue wire in 'faith'.

Anyone who can explain this to me I would REALLY appreciate understanding. Maybe V=IR doesn't apply in Japan

I think I found what the problem is. If I unhook both connectors traveling to the rear of the SUV, the back up lights still light up in REVERSE. So, the reverse wiring is not the same as the 2006 Sequoia.

My understanding is if I'm not installing a backup camera, I don't need it anyway (?).

When I get the 70-8113 harness, I'll post and let everyone know if it worked.

Ya, I didn't hook up my reverse wire in my 06 Sonata. Just capped it and tossed it somewhere. Since I was installing a Z1, I did the bypass and just grounded the parking break + special pin, and tapped the VSS wire.

I installed one of these a while back. And the harnesses will not work except for at amp. The amp is underneath the center console. I tapped into Acc at the radio harness. I bypassed the amp and put the GEX-10XMT there.

Correct. Why hook up a reverse wire if you have no backup camera to use when backing up??

The 70-8113 interfaced to the factory plug just fine.

I tried the Blue/White remote wire to the Amp Turn on Blue/Wire and it apparantly does not turn on the AMP since I have absolutely no sound. Nav system works great (and man is this a nice unit!).

Some questions:

I hear folks say they by-passed the amp. Can someone describe that process?

I'm assuming you remove the center console (how?) and gain access to the amp. Do you then just jumper the speaker wires from the input to the output?

Look to bypass the amp there are two screws underneath the cupholders ( this was a few months ago...) pop out the switch panels on the center console (USE A GOOD PICK SET!! Bojos work best). Couple of scre-ws in the center console and it should come apart. Then to bypass the amp dont run a jumper but take the Speaker wires coming out of the AVIC and run them down to the amp. Use your DMM to figure out incoming and outgoing. if i remember right the positive and negative were above and below each other on the big harness. pink/black, red/white, a yellow set and purple. (DONT QUOTE ME. I AM SITTING AT HOME). but after you do that you should be straight. I put the GEX-10XMT in the amps place. Worked fine and no complaints from customer.

Tx RP*. I realliy appreciate the explanation.

Put a TYTO-01 in. Works great. Excellent sound!

I had thought the connectors would not work last week and returned the TYTO-01, but I think I was looking at it wrong.

XM sound not working but I think I got the cable plugged into the wrong connector on the XM module.

Just need to program the SWI-PS. Tonight hopefully.

No problem. If you need anything else just let me know.
