Installing New NAV Software?

The Nav software is on a DVD behind the monitor screen, where the CD slot is. From what I understand, it is just a matter up ejecting the existing DVD and loading the new DVD.

I cannot help you with the differences in the update.

 

Normally the updates aren't significant enough to warrant upgrading every time a new version is released. I normally wait 3-4 years before investing in an upgrade...

 

Version 9.1 is a disaster around where I live - incorrect addresses, missing streets and towns. I have been in touch with Toyota constantly over this issue. They asked that I tell them some of the specific problems I was having and they tried it on their V 10.1. Surprise - the new version sucks as badly as the old. Don't waste you money on an update. Spend it instead getting a Magellan or Garmin. For anyone out there contemplating the Toyota NAV - don't do it. Speaking to Toyota about its problems is an exercise in futility, unless you really enjoy being lied and BS'd to.

 

Out of curiosity I called my local dealer and was told it would be $260 CAN. and he, (service manager), says don't bother, it's not worth it. I assume the info is from other customers that he received the feedback. I personally gave up on the Toyota NAV system and now use Garmin. Save your money!

 

Not sure who does their mapping, but maybe it's Felix the Cat for all I know, or the menehunes. Other Toyota GPS-based systems are much more up -to-date, but it seems somehow there's little or no crossover to the Prius DVD. ¿Que pasa? Toyota... :noidea:

 

I bought my Prius in November. I had just purchased a TomTom auto adapter for my iPhone but returned it because the Prius I chose had built-in Nav. I think I made a mistake. Most of the user experience of Prius GPS is inferior to the TomTom GO 930 that I had in my other car. And the v10.1 maps do seem more error-ridden than most GPS maps.

I am thinking of reordering that TomTom. Their maps aren't perfect, but they are much better than those on the Prius, and a lot less expensive: not $250+ per year, but $100 altogether for 4 updates per year as long as I own the unit. Sure, the suction cup has to be re-wet every few months and replaced every year or so. But what's the use of a built-in system if it can't tell east from west?

 

Seems interesting... if it aids GPS navigation flawlessly I would wanna give it a try :rockon:
My work involves a lot of local travelling and certain times at such places where there is not even a single soul to ask for direction and hence, if this embedded software works well... I am a game for it...

 

No GPS is flawless. And I am comparing about three years of use of the TomTom with only three weeks use of the Prius. I will probably wait a few more weeks before I decide for sure.

 

Does anybody actually have Nav-DVD v10.1 (for 2010 Prius)?

Here, they want $200.

Has anybody made a use/backup copy of v10.1 yet?
I use the "backup" copy in the car
so that I can safely preserve the overly-expensive original.

To make a Backup:
It is a Dual-Layer DVD, so make an ISO file first, directly from the original,
then burn that ISO to a dual-layer DVD.

 

I bought mine from ebay for $105.00 its 7.3 GB
Toyota Lexus North America Navigation 10.1 DVD U92

 

What do they do to the DVD to make sure it can only be used in one car?

 

OK thanks for the answer. I don't intend to become a "DVD pirate" I was just curious if they did something to it when you purchased it.

I too have made a copy of my ver 8.1 as a backup. As Garygid stated you need to copy it as an iso to a file then burn it to a 8.5 GB dual layer DVD. It works just like the original. Burn at a slow speed using something like ImgBurn or Brasero.
