2006 MFD and NAV

<div class='quotetop'>QUOTE(eflier @ Apr 1 2006, 09:12 PM) [snapback]233639[/snapback]</div>

Here ya go. My car is a Feb2006 manufacture date. It's tough to get a good photo in those cramped quarters under the seat. You should be able to recognize the connectors anyway. If you want wire colors, ask.

My NAV-equipped MFD images match the "Type 1" images in the main manual. There are also examples of Type 2 and Type 3.

The following observations are going to read like one of those logic puzzles. (Remember them? John has a dog. The owner of the red house has no dog. Etc...)

A. Type 3 images appear to be the older style, with "recessed areas" for certain written legends in the display. Consider the Consumption Graph. For Type 1 and 2, it has no 3-dimensional appearance. Type 3 displays have a recessed-block appearance for the Current and Average areas of the display.

B. Type 3 appears to have a gray background, though I believe this had four settable colors. Types 1 and 2 are always black.

C. Hard buttons are different:

Type 1 has four buttons to the left of the screen (display, info, climate, audio) and three at right (menu, dest, map/voice). This appears to be the case for a NAV model.

Type 2 has two buttons to the left (climate,audio) and two to the right (display, info). This obviously is a non-NAV system, because it lacks the proper complement of buttons.

D. Types 1 and 2 appear to be the higher-resolution display.



To summarize, there seems to be an interesting situation here:

- Type 1 and Type 2 displays appear to be identical; the difference is simply that Type 1 has NAV;

- Type 3 appears to be a Type 2 (non-NAV) with the old display screen.

I think I read somewhere that early 2006 non-nav cars had the Type 3 display. Perhaps the new display was late in arriving.

Thus, according to the main manual, my conclusion is that all 2006 NAV models must be the Type 1 hi-res display.

My separate NAV manual (p/n 01999-047529) shows only a single display type, which matches the Type 1. It has no mention of the other types. Assuming your other owner has NAV and an old display, he must have a different NAV manual than I do: ask him for the part number printed on the back.

 

My CF card reader seems to have wandered off, so I can't post the pictures I just took. However, they look just like Rick's. 2006 Package #7 with the new high-res display, built 11/05.

I'll post the closeups of the connectors as soon as I find my adapter...

That could be it. Suppose they installed the new display hardware, but they still used the old software? Then, when the new software was ready, they began using that. We would then have identical connectors, but his displayed graphics would be different.

The next question to ask: Do his non-nav screens look new or old? Remember, if there is an "inset" 3d appearance to the Consumption screen, then it's the old graphics. Maybe not old hardware.

It isn't documented in the manuals either.

 

What version of the nav DVD does he have? Mine is 5.1. An older version could explain why the nav screens look different, and perhaps a DVD upgrade would update his nav to the current appearance.

But the non-nav screens, e.g. Consumption, are not produced by software on the nav DVD: that software must be inside the MFD. I wonder whether Toyota has a flash-ROM upgrade for that, or perhaps a socketed ROM part, or maybe nothing.

If he truly has a digital-video MFD with older software driving it, perhaps it's worth having him ask his dealer about an update.
