FYI...

Here is the wire diagram for the hack

edit...I like to keep a copy of this type of stuff so I can remember what I did to the stereo.

Question regarding the nav override kit. Which button (DVD or Nav) is used in order to see the folders and files during music playback. I understand the Nav button is only activated for 5 minutes max. There was a reference to this in a previous post but I wanted to make sure.

Thanks...

man...this thing worked like a charm!! (including the switch install) Freakin awesome! thank you for the write up!!!! I bought an ipod adapter and did everything at the same time.
Just a couple words of advice:
follow directions very carefully.
the white wire w/ the silver paint is actually just solid white. There are 2 other white wires on the same connector, but have stripes in them, I think one is red striped, the other is black. The wire you want is solid white, with no stripes. There is silver paint thats on there is more like if a kid took a silver paint marker and randomly wrote on all wires.
Also, most of the wires coming out of the P1 connector go straight down to another connector lower on the nav unit. So when the write up says "wire loom side" try to ignore that lower connector and pretend that it actually goes into a wire loom. So you have the wire loom side and the connector side.

The Red wire out of the J50 connector needs to be grounded. you ground the wire on the connector side this time. (the other wires you're concerned about the wire loom side)

I did the DIY part 2 where you install the switch. I don't like how jumpy it is, so the switch is a big fat

Anyway, thanks again to TIM817 for the awesome writeup!! I seriously can't thank you enough.

Sorry if this is thread hijacking but:
Here's some more info if any of you are interested in ipod adapters while your in there. (look for a post by "drive01" almost towards the bottom of the page) http://my.is/forums/f159/lexus-ipod-...on-kit-353171/

Is there anyone that lives near Burbank, CA that is willing to do the NAV HACK for me? I am willing to pay a little $ for your time.

I'm a total newbie so I'm not very comfortable / confident in doing this.

Thanks.

You should post a request in the SoCal Forum.

We have a bunch of members that have done it...

did you put a switch in? If not this is the problem.

japkong

switch? no? is it easy to put a switch? so it does need a switch to mod the navi?

In order to do destination while in motion. If not then once you are traveling around 5mph or so it will lock out the navi so you cant input anymore. The switch allows you about 1 minute to enter then switch it back when done. Its easy to install and worth it since you have done the rest Technique did this on his thread or there may be some info posted in this thread. Probably the easiest is to open that thread and see. If that doesn't work let us know!

japkong

passnu 2, thanks for your answer, so we can not use the navi without the switch? do you know where you can buy the switch? what size of the switch?

Your welcome!
i just got an automotive switch from radio shack for like 2$ or maybe less?? cant recall now. Others have a toyota/lexus switch and mounted it next to the switches on the dash there are a few empty slots. You can mount this where you find it to work best for you.
