Insert DVD Navigation Disk

[garygid]

When a new version of the NavDVD is inserted, it takes some time (minutes)
for the new software (or whatever) to be read into the internal (probably flash) memory.

Sounds like either:
the DVD player (reader) is having trouble reading the DVD (most likely),
or the "internal" memory has gotten messed up (less likely).

The two most common reasons for the DVD not reading are:
The DVD is scratched (possibly by the read head itself) or dirty
(easy to remove the DVD and check),
or the read-lens is dirty and needs cleaning (harder to do).

The third reason is the use of too much "grease" on the moving parts of the drive,
which gets to "stiff" over time, and at lower temperatures.
Unfortunately, disassembly of the drive (and removal of 99% of the grease)
can be very difficult and time-consuming.

I would hope that they checked the disc to see if it's scratched or damaged, but who knows. The fact that the problem appears only sporadically makes it hard to diagnose. I'd imagine that a contaminated/damaged disc or reader would result in the problem occuring all the time. The third possible reason you mentioned, the grease getting stiffer at lower temperatures, sounds like a possibility because it does seem to occur when it's a little colder. However, since the car is very new (got it at the end of July) and the weather here has not been that cold yet (mid-thirties has been the coldest so far, and the failure has happened while in the mid-forties or so), it doesn't seem very likely. But what do I know?

Whenever it happens and eventually reboots, the reboot takes several minutes. What's particularly annoying, apart loss of use durng the error and reboot period, is that each time it reboots, I lose all my nav/voice settings.

Toyota's Customer Experience Center is 800-331-4331. The Toyota Owner's Online site is here: Toyota Owners Online | Official Toyota Owners Website You will need your VIN and you can create an account, then just look for the "Contact Toyota" at the bottom of the page after you log in. You can send an email from there.

I think a photo is a good idea or maybe just try to drive it in with the error and have them come out and look at it, if it will stay broke that long.

I called the 800 number and they said they'd get back to me by COB Monday. Let's see what they have to say.

Toyota called me today and they told me they are still working on the case but they hadn't heard of this issue before. I told them that I have heard of three other people who have had the problem.,

If you are experiencing this problem, please call Toyota's 800 number so that they know there is more than one person having this issue.

It happened again yesterday. This time, it didn't just freeze. It was flashing like it was starting to reboot. Then it actually started a reboot but looped back into error mode. Eventually, it did reboot, but took 5 or 10 minutes.

guys,
To those who have this problem, it usually is caused by moisture which has accumulated in early morning. Those who park their cars outside are more likely to face this issue. It is certainly not owners' fault.
Toyota might have a batch of NAVI units that do not have sufficient design consideration for moisture, which accumulates on disc or len of laser reading head.

Try this.
- put some lime desiccant packs around the head unit
See if that helps. If yes, you have found the cause. Tell Toyota about it.
You should demand for a new head unit AFTER they find a fix.

My gen-II had that happen once only. Never happened again. However, my Prius is always parked inside garage overnight.

And ... if your DVD is clean ... your reader may be dusty. Been off roading, eh?

sounds like an intermittent power failure, that causes the nav-unit to loose its settings and need to load the sofware from the dvd again.
I don't think it's a problem with the dvd

How has it been "acting up"? What do you mean by you "do not have the DVD" -- did you mean you don't have the error message?

The instructions for checking the version are in the navigation system owners manual. I think it's the Info button.

Sounds plausible. When you say to place them round the head unit...where/how would I place them?

Recently, it's been quite cold first thing in the morning (low to mid-thirties, but not below freezing) and I haven't had a problem.
