Thanks Technique

.....worked like a charm. I might add I actually did it on a "Hackintosh" OSX on clone hardware, using "burn" and open source burning application (in Joliet mode)for OSX, and a Sony Drive with Memorex +R DL media, in case anyone has similar hardware, that worked PERFECT for me!

Did you unplug your fuse to rest the hardware, after installing the new disk?

Sounds like youll lose the memory of the HVAC recirc setting after you turn off the car (itll always revert back to one setting) and there is the possibility that you may have future problems with the GPS holding on to sats, asl well as not connecting to as many as it connects to the 6.1 version. There is a possibility that there are some bluetooth loses too.

Has anyone talked to any Lexus technicians like from the dealerships and asked them if they know about a bypass like the 5.1 had? Anyone know any techs personally and could ask or have them ask around. I do and Ill try poking around a bit.

IS350 Nav override

I called a No. VA service manager and left a message asking about the override for the Nav upgrade. She didn't call me back. No surprise there.

Isn't there a way to see how many sats are connected, with both versions?

Also, the versions aren't fully effective unless you pull the fuse and reset, correct?

Well, its more like the nav unit will not downgrade the firmware to the 5.X until you pull the fuse. If you already have the 5.X firmware I believe it i will update to the 6.X just by putting in the new DVD.

Exactly correct. The system will not back rev if you only install the disc. You have to kill the current firmware by pulling the fuse to force a firmware load from the DVD.

But again, if you pull the fuse, and eventually put a newer map disc in, will the firmware automatically upgrade, preventing the override?

I think he mentioned something about using the brake line but he was very vague. Ive also seen something here about connecting the brake wire to another one but I want to make sure it has no setbacks before i attempt anything. I just called his partner @ Lexus 5 mins ago and he told me that the tech is in atlanta @ Lexus Training ! He should be back on wednesday..Hopefully he learned something that will help us!!!!!

Help!

Man!!! Im trying to get that damn Clock face off and its just not coming out! It was really hard in the first place to stick those tools in there and I tried wedging a very thin screw driver in under the emergency button (in the seal below it) but pulling that towards me wont make it budge... What I am doing wrong exactly. I tried the tape method too only to find that the tape wouldnt stick. Where did you guys stick the flat head screw driver to pull this thing out?

Nevermind, got it. Have to work each side out with the tools and the screw driver...
