Chichum - That's great stuff man - Thanks for taking the time to research this and also share it with the rest of us. I'm not sure why others were hating on the thread - but that kind of information is very helpful! My wife just traded in her XA for an 08 XD - instead of moving over her old Pioneer AVIC-D2 she had (and lose the Ipod/Aux and Steering controls that came with the XD) we decided to go along with the Factory Alpine navi system -
I did the bypass on both of our Pioneer AVICs - Thanks to the information from the folks at www.AVIC411.com - so it's great to see that I can do it to this Alpine one as well - Thanks again man and great work!!

 

is it true that you lose steering wheel controls after cutting the wire?

 

No, the entire harness is for the steering wheel control. The yellow wire is the one that is hooked to the speedometer. So if you plug the harness back in when you're done, the rest of the buttons will continue to work.

 

That wire is purple in the Scion XD BTW!

 

2 quick questions:

1. does anyone know exactly how this mod affects the warranty ?
2. any suggestions for a good,clean,stock looking switch and its install location(for xD preferrably ))

 

mod will screw with warranty if and only if you are stupid enough to get caught

you are afterall bypassing a safety interlock placed there for legal reasons.

for the switch, you can run it to the switch panel and buy a nice switch from home depot or lowes... or you can also use a small switch of the sort and hide it stealthily.

location is still your preference.

 

To further clarify the first question: does anyone know EXACTLY how this will affect the warranty ? Will it cancel the warranty on electrical system only, full bumper to bumper, etc. ?? Anybody's working for Toyota/Scion please reply

SquallLHeart, what exactly do you mean by "getting caught" ? I hope my car never needs any electrical warranty work, but if it does - what do I do ? Reverse the mod ?
I remember one time the dealership tried to deny a warranty service because I had aftermarket rims These guys will use any reason to blow you off ...

And with the switches, I'm sort of a purist, so Home Depot, Autozone and Radio Shack stuff doesn't do it for me. Does Gucci make any switches ? Just kiddin )))
Any more suggestions, pictures of your setups ?? Thanks !

 

can anyone confirm this works for the 09 tc? and where is the location of the wire I am cutting (behind nav, below steering wheel and how do I access them?)

 

yes.
behind the nav.
remove the nav and the panels related with doing so.

 

Ok, but how do I get behind the NAV?

 

Just a thought:

Is there a way to release that pin from the plug? That way you could just pull the pin out to disconnect without cutting the wire. Put the pin back in if you need to have warranty work done.

 

Check this post http://www.tundrasolutions.com/forum...nav-your-07-a/

On page 22 of the pdf it shows how to remove the pins from Toyota connectors.

p.s. I have the .pdf but couldn't upload it here for some reason. PM me and I'll send it to you if you want it.

 

Sorry I'm so late on this but yes there is a way, and I highly recommend that you simply pull the wire out of the harness rather than cut the wire, it will be much cleaner since you won't have to splice the wire back together later on, and also for warranty issues when you take it in you can just slide the pin back in and it will appear stock, they may get suspicious if they see the wire is spliced...Here is a video on how to remove the pin, it's a video of a Buell harness but it's the same exact concept...

I just got a 2010 with alpine w/navi.. anybody know if this method will work for the newer models?

 

^^Just try it and see, it won't hurt nothing...

 

Chicum,
I got the sns online and just ordered the video input kit through optomizescion.com friday. I wanted to bypass this for a while but I had a few questions.
I live in Philly and had a guy install my head unit but he said stock units are near impossible to hack. From what your saying all I have to do is cut the yellow wire. Now I read the conversation and i know you said nav will continue to work fine without the yellow wire however will this mess with arrival times and all that? Also i see that your in pa...if your anywhere near Philly you can make a few bucks, especially if you put a switch in since that seems better. Let me know as soon as you can.

 

I know I am resurrecting a long-dead thread, but I specifically joined the forums to resolve this same problem for myself. Any help would be greatly appreciated!

exit349, I have a very similar story to yours. I bought an OEM Alpine navigation system online for my '09 xB, and brought it to a local car audio shop to get it installed. I went through a couple aftermarket nav systems in my old xB and the full-functionality-while-moving issue was easily resolved by grounding the emergency brake, so I assumed that this was all that I would have to have done to this one. However, this obviously didn't work, and the installation guy said the same thing as yours: that factory systems are nearly impossible to hack. He is under the impression that the functionality is disabled from the GPS satellites being able to tell that you are moving, and that cutting any speed sensing wire probably wouldn't be enough to do the trick.

So my questions are as follows: is there any reason why this method would work in a tC but not an xB? From what I understand, the same factory nav unit was used in 2008-2009 xBs, xDs, and tCs.

Since the navigation system was not factory installed, there are obviously no steering wheel controls. Would this change anything?

Lastly, regardless of the wires' colors, has anyone proved that the wiring map provided by Chichum is his original post is the same for all 2008-2009 Scion nav units?

Seriously, any advice would earn my undying gratitude
