Any way to prevent the initial "welcome" nav screen

Does anyone know how to get into the nav service menu to disable the initial nav disclaimer screen? How many times do you have to "agree" not to watch the screen while driving. Is there a way to permanently disable it? Thanks.

PS - If it matters, I have an '05.

You need to modify the Navi program. Not something everyone knows how to do it. Just agree the system, that's probably the only thing you can do.

Is there a place where I could find out how?

Contact this company. They make a "NAVI Kit" for Toyota Prius.

I've seen this mentioned on another forum, but on one had received it. Orders supposedly dated back to Oct. and they also said they had received no response to emails. Has anyone received or tried one?
