Should also mention a google search revealed a company named Prestigious Society in Valencia, California that advertises harnesses for various Lexus vehicles around $300.00 The "lockpick" harness is apparently not yet available for the GS.

Hi, Can you PLEASE tell me where to get the instructions on how to perform this bypass? thanks If you have an "06" GS, the instructions are half way down on page 1 of this thread. I have an 06 with Mark Levinson and Nav., and did this mod and it works as described. I don't know about the 07 difference. If you have an 07, I would read more of this thread. Ive done this through a local mom's and pop's audio/stereo shop, he was slow to want to do it, but after I told him I took rsponability if he broke anything, he did it, it took him 15 minutes AND IT WORKS!!!! Problem solved on 2008 GS350 with Navigation and Mark Levinson: I purchased and had installed a USA-SPEC PA20-TOY iPod interface for my 2008 GS 350 with Navigation and Mark Levinson. Worked fine until the car started moving and then most of the controls "grayed" out as expected. Followed the advice of an earlier forum member and contacted Steve at Auto Specialists now located at 8507 Garden Grove Boulevard, Garden Grove, California 92844 (714-534-9440); $150.00 and an hour later everything worked perfectly. Steve is extremely courteous and the modification was performed with great care. There is a small toggle switch which I only need to engage when I choose to enter an address into the navigation system while driving (causing the map to jump a bit). Otherwise, I choose the other position, the GPS resets, and everything works as if the care was stopped, in park with the emergency brake on, including watching DVDs, the telephone keypad, the controls on the USA-SPEC, etc. If you need specific technical information please contact Steve ... I can report the override is working perfectly and something I would never attempt myself.
