Prius MFD Operating System

[pkhoury]

Here's an interesting question I was thinking of - does the Prius (new or first/second gen) run an off-the-shelf operating system and hardware for their MFD, or is it a custom Toyota-Internal solution? What about the hardware? Being a techie, I've been wondering this for a while.

An interesting question... maybe a derivative of Debian or some other *nix?

My bet is ITRON.

I thought it was Linux.

Here's some info about Itron, which would be my guess (not that I know).

Makes me wonder. At least I've never seen the MFD crash or hang. Unlike my Samsung cell phone (I swear it runs Windows CE or something) which always crashes.

Also, I take it nobody has really hacked into the MFD, or got a command prompt or anything? Any ideas as to the actual hardware used for the ECU (cpu, etc)?

Given the tech allure of this care, I am simply amazed that this hasn't been done! Certainly some techie type wants to come up with a FREE way to defeat the "gray" syndrome when in motion, which may be "safe" but is extremely annoying. I mean, 300 is a lot of tamales to pay for LockPick, I'd rather get some speakers...

I've poked around in the boot file of the Nav DVD. There are references in it to various /dev devices like /dev/cd/cd1/slot0/ and /dev/avc_lan, which is a unixoid sort of thing.

And this is for which year? I once copied the PCMCIA Type III hard drive for a Toyota Sienna
Nav system while I was in the shuttle van, and the files appeared to be DOS based.

Anything with /dev is definitely UNIX based. It sounds like Linux, but I'm a Solaris kinda guy.

But back on topic - has anyone here actually taken apart the ECU? I'm seriously curious in addition to OS what kind of CPU, RAM, etc is in there. Considering that the Prius is esentially a computer on wheels.
