The new disk is version 4.2. It installs in a CD reader located under the drivers seat. The setting up of destinations is not quite the same with this new NAV as with the previous NAV system. Also, it is not particularly intuitive. Unfortunately Toyota did not provide a set of written instructions explaining how to use the new NAV system. I will call Toyota customer service to see if they can provide a set of instructions for the new NAV system. I have used it extensively for the past two weeks and have found it to be deadly accurate. It has never missed in bringing me directly to any destination I have entered into the map. If you don’t know the best route to get to your destination, you merely program the NAV with an address and city and it will take you to where you want to go. If you take an alternative route which is different that the NAV’s suggestions the NAV will recognize that you have not followed it’s suggested route and will adjust itself to your new chosen route and will bring you to your destination.

Any clue what the date of the data is (hope that's clear)? I live in Boston area and am delaying upgrade hoping to get as many Big Dig changes in as possible.
You should see a little icon named "Map DVD" in the upper right section of the screen. Hit that and you'll see your version.
Hi rickkulp - ! All of my previously set routes were still there after I upgraded to Version 4.2. The only adjustment I had to make was to re-set the Region to "Texas/Oklahoma" (5). Since the NAV DVD is "read only" it would be necessary that your routes and memory points would be resident in your Prius' memory rather than on the DVD. All NAV features seem to work as before and I have noted some updates to POI's (Points of Interest) and new streets and highways.
I posted the date of the files in another thread and I'll post it here as well. Most of the (relevant) v4.2 files seem to be dated 9/2004. The v3.2 files are dated 11/2003. Copyright on my v4.2 disk says 2003, as Rick mentioned earlier in another thread.
Although the file date on a given DVD is say 9/2004 the actual map and POI content can be and, often is, much older (9-12mo is not uncommon).
Arizona Charlie, You say, “I have used it extensively for the past two weeks and have found it to be deadly accurate. It has never missed in bringing me directly to any destination I have entered into the map.†Did you find this not to be the case with your “old†DVD?
Oh yeah! I mentioned that the files on my old version (3.2) were dated 11/2003. Regardless, an entire shopping mall is missing that was built over 3 years earlier.
I got mine replaced two days ago. The only noticable difference that I see is more corporate logos in the fast food and other icons. Also, Dunkin Donuts seems to be classified as a generic coffe house (coffee cup) now which is better than a generic fast food (hamburger) icon. It doesn't have new road changes in the last year. I don't recall any particular problems on the old one that might have been fixed.
Like I posted before...I have 4.2 installed. It now does not map the area where I live...Green Valley AZ 20 mi south of Tucson. I have an appointment with Toyota service Tuesday to reinstall my old software (4.1?). Old software mapped the area where I live (Green Valley) and "Agnes" talked me right to my front door. Ver 4.2 does not do this...Agnes says something like "there will be roads with incomplete data and turn by turn guidance will not be available".
<div class='quotetop'>QUOTE(AZstan\";p=\"59759)</div> This sounds like the same behavior as the system in the '02-03 Prius. It uses NAVTEQ data overlaid with GDT data in areas where NAVTEQ doesn't have Detailed City coverage, but uses the presumed less reliable GDT data only for map display, not for routing (NAVTEQ now has coverage equivalent to GDT outside Detailed City areas, but Denso has apparently chosen not to use it). The previous disks for the '04-05 used only GDT data, so it's not excluded from use for routing.
<div class='quotetop'>QUOTE(AZstan\";p=\"59776)</div> I don't think a version 04.2 exists for the '02-03 - the newest version I'm aware of for the Classic is 04.1, and it usually gets only one update per year. The purpose of the update for the '04-05 appears to have been to replace the single data source previously used on the newer nav system with the data sources used for the older models.
I had 4.2 installed on Monday and hated it immediately. It couldn't recognize the one and only way to my house - which it knew with 4.1. It also kept trying to get me to go on other streets that I know to be dead-ends. I also tried to drive me into the San Francisco Bay and through the city dump as a short cut to my house. BTW, there are NO connecting roads where it was directing me. I called the dealer to complain and they took me right in. Tried to re-initialize the DVD but that changed nothing so they reinstalled 4.1. I'm MUCH happier. I'll wait for the next update and try again.
Wednesday I upgraded from version 3.2 to 4.2. My initial experience is not encouraging. My home is still shown as 200 yards or so from where it is. A friend's home is shown at the entrance to the subdivision, not the back of the subdivision where they live, and the others in the sub appear to be the same. It appears that rather than driving 300 yards into the sub and mapping the data, the data collectors simply defaulted them all to the sub entrance. I really like the NAV system, but the data on my Microsoft Streets and Trips 2003 appears much more accurate, with many newer developments included that the Prius does not have data for. I have found 10 year old developments the Prius does not have data for. The Microsoft 2004 version with the GPS sensor also appears to have higher resolution than the Prius system. As a result, the 20 - 50+ foot errors which appear often with the Prius system are dead on with the Microsoft version. I think Toyota needs to review what they are getting from their supplier. While I am impressed with the NAV system in general, it does appear to have the worst data of any factory installed NAV system I have experienced to date.
