thanks. i'll have a look at my firmware today. Only thing is I can't find the stupid tools to remove the clock face. They don't seem to be with the tool kit in the trunk, and I just bought my car a few weeks ago!
In answer to your question, yes, we do know... It's a Hitachi SH-3 or SH-4 processor...
Details:
"CPU (IC201): Hitachi SH-3E, HD6417718R" (Credits to Sonartech)
And I bet I know your next question... And unfortunately, the answer is yes, we suspect the entire language/os is proprietary...
I bet it's still a RISC based processor. I seriously doubt they'd build a completely proprietary platform. You need to develop too many tools in house to write and debug software to go that route. If the microcode is RISC, it can be disassembled. It just might not be pretty in C once it is pulled apart.
There are other ways to skin this cat. I doubt it is impossible to hack.
Most performance mods need a watch and timed course to demonstrate actual improvement. Few deliver the advertised claims. Many are actually worse than stock. The best performance mods are made to the driver.
Emotional arguments - They're not just for chicks anymore.
I am looking forward to a smart person/persons figuring out the override for the new Nav disk. I have a 2006 IS350. The old override worked great. Other people could use the nav system while I drove. Now, I either have to stop, which I typically don't have time for, or have a friend look at a printed map and try to give me directions.
Lexus, please offer an override! I will be calling the 800-255-3987 number tomorrow.
Is there a way to eject the dvd manually? I tried to install a burned nav. dvd that does not play and i can't access the menu to eject the dvd
What does the screen say? If you are getting the japanese letters, just press upper left, lower left, upper left, lower left and it should eject...

Okay so did we get anywhere with hacking the kiwi file??? that wasovera month ago...
Nope... Nor will we ever unless someone is an assembly language genius or they can get us hitachi proprietary software... Or we find someone sympathetic at Denso...

Well Im pretty good with assembly, but reverse engineering code and trying to then apply it to a system we know little about would yes require a very resourceful individual.

.....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!

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