Glaring NAV version 4.2 system errors

Re: Glaring nav system errors that could affect everyone

Does anyone know the version of the updated Navigation CD?

 

I'm planning to order the upgrade when I go in for 10K service Wednesday. I recent;y got home from a vacation in South Carolina and over the 2700 mile trip we experienced a few errors (being routed to an obviously out of the way, remote area that was supposedly a freeway on-ramp, being told to exit a freeway in Charleston, SC where no exit existed, being told a restaurant was about four blocks and across a few streets from where it actually was), but for the most part it still got us everywhere we needed to go.

What would be nice is a "smarter" auto re-route system. On many occasions, we'd have a clear route, stop for gas without suspending guidance, and we'd get rerouted onto a bunch of backroads once the car was turned on again. Or we'd look at a map and see that two highways intersected, but the NAV would want us to get off earlier and drive on city streets to connect to the other freeway. If we missed the exits, it kept trying to reroute us on backroads instead of just sending us on the freeway.

When we got closer to home, we knew the way we wanted to go, but the NAV had us going a way that was 50 miles longer. We had to keep going until there was literally NO POSSIBLE WAY for us to get home otherwise before it figured out what we were doing. Moments before, it was telling us to do U-turns and drive over 50 miles out of the way to get back on it's chosen route. At one point we were 30 miles from home and it wanted us to drive like 88.

......for a small monthly fee, of course. :naughty:

I'm also sorry to learn about the anomalies in v4.2. OTOH, I'll take my chances since my 3.2 version seems to be about 2-3 years out of date.

 

I have version 3.1. I will probably upgrade sooner than later due to strange quirks like last week when I drove from my home in Cary, NC to Reidsville, NC. The system had me on I-40W and then taking the I-85 exit going north, then the 1st exit and then crossing back to the I-85 southbound on-ramp, then back to next exit I-40W to continue on the orginal route I was on.

dejavu! Same story as version 3.1 Nav.
Whatever happend to the 'fix' which Toyota customer service promised to all the V.3 owners? :cussing:

Toyota and Lexus, your Nav simply sucks!!! Dump it and go with the Honda/Acura version of Nav. And please get rid of the speed sensor.
Improve the graphic and color
Improve the voice recog.
Improve the accuracy. I don't want to get lost because of nav. That means I got a stop and ask for direction.

Oh, well... looks like I am stuck with v.3 Nav and paper maps for awhile.

 

oooops, I should have read the other posting. Sounds like we are getting the fix soon. Yeahhhhh!!!!! :lol:

Hope to see some improvement.

 

how do you check to see what version of NAV one might have?

 

bcool how long have you had your car? i was under the impression that the free fix was a new as yet unreleased version. do you have an 05?

You can probably use the diagnostics screen on the MFD (or whatever it's called) but I just ejected the DVD; the version number is printed on the label.

The drive is under the driver's seat. There's a faceplace (cover) with two tabs. Push down, remove the cover, and slide the tab on the left (labeled "open") to the left. The DVD will pop out.

 

Yeah, I believe someone on here has already posted having version 4.23, already a version newer than bcool's or the update we're all getting for free.

-m.

 

I'll take my chances with a *FREE* version 4.2, rather than waiting until next year for one that might be more correct, but cost me $200-300.

BTW, there is a "DVD" icon in the upper right hand corner of the MENU screen. Press the icon and the next screen should show the version number. This sequence works for version 4.1, I don't know about version 3.x.

 

My Prius is in the dealer right now for a Check Engine light. I asked them if they can perform the update and they said that they haven't heard anything and that "Us Prius owners always hear things before the dealers". So, if they can figure it out before the end of the day, I will have mine updated.

If I understand the TSB, it is good until Dec 31, 2005. So you should be able to get it done any time in the next year without cost. We are assuming they will use whatever the current DVD disc is at the time rather than making 22,000 of the current one now and sending them to the dealer upon request.

Probably not as they have to order the DVD. They probably can't get it in the same day.
