finally found the rocker switch whose size is the closest to the panel cutout, and the material closest to our console panel (imho).
the p/n is JWL11RA1A, requires cutout size 29.5mm x 20.5mm, which is slightly wider than our panel cutout 30mm x 20mm. guess filing .25mm off the cutout on each side is a no-brainer easy task. one extra work is file 4 rounded cutout corners to fit the non-rounded switch casing, which is also a <5min job even you want to do it carefully.
note I've done dvd/phone mod a while ago. many thanks to quezacotl's nice wiring diagram!!!

Well done, it is not too tall for the center console to slode forward is it?? I found some switches that are small enough to mount on the plastic popoff clip itself....

 

it's about the same height as the adjacent ETC switch. the armrest still has good clearance to slide over.
this rocker switch is made by a Japanese company named NKK. the plastic material looks pretty much identical to that of the panel, so blends in nicely imo. $7.99 a piece ordered form digikey. not cheap but worth every penny because it preserves the classy/clean look of the console. prior to this, I tried 2 other AM switches for some toyota/scion. the material quality was no comparison.

also for the smaller one to mount on the insert....ummm, sorry but not my option.

now I am so happy with the mod because I can enter address and check POI any time I want. it makes much more sense to use it this way. otherwise, the nav is just a scrolling map.

 

I have a 2007 GS450h with nav and ML,and want to have the nav mods and an ipod adapter installed. I live in San Jose, CA - does anyone have any suggestions of a good place to get the work done? Thanks.

 

yeeeeehaaaa!!!!! done in less than 2hrs! I can't believe I missed this thread when looking for solution for '08 450h about a month ago.

Thanks to all of you that spent own time to make other people happy!

 

I noticed that the VAIS website has has a forum with a lot of "locating installers in X" threads.

 

Hey everyone, just got a 08 GS350 and had a company in Socal (Bluetooth Valet) do all the nav override, phone override, dvd override, iphone integration and sirius sat radio utilizing the shark fin antenna. They did an amazing job. came to my house did it in my garage in less than 2 hrs! Highly recommended! They are based in San Diego but I live in LA. Also when you sell or get rid of the car they uninstall everything and put it into your new Lexus for a very small fee.

I know most people can follow the directions above but I was uncomforable cutting wires and stuff.

 

GUYS after sucessfully done with your nav hack and adding a switch for navigation and POI entry. What the total time you have before the NAV goes back to lockout mode?????

 

^ if driving in city (40 mph or so) - maybe a few minutes (enought time usually) but on hwy, maybe a minute, and you rock switch back and forth and it resets again

 

On mine you just press the switch and it overrides it for an unlimited amount of time. The gps wont work though while the button is pressed so you have to remember to switch it back or it wont track you correctly. every 45 sec or so the screen will grey out for a second (while the system overrides the car again) and then come back on. This way you can get around the system kicking you out every 60 seconds.

 

Anyone know if there are any places that offer the same service in the East Coast (New York State preferably)?

 

Anyone know of a place in westchester NY or southern CT that would do a bypass?

 

For these inquiries, just start a new thread and ask...

 

My hybrid disc does not allow me to dial BT phone on the nav screen in motion and as far as I know it only works with the cutting wire modification.

However, this guy proclaims http://www.tundrasolutions.com/forum...west-v7-1-nav/that his hybrid disc allows the TOYOTA nav to make a BT dialing in motion. I pm'ed him and he confirmed it affirmatively... of course he is selling it but I just can't believe it actually works.

Note: My hybrid disc is 6.1+5.1 vs. he is selling 7.1+5.1, could this be the reason?

 

Anyone in Dallas,Tx do the wire hack on a 2007 GS 350 ???
