You don't have a problem with your vision, do you?

Seriously, Nav lockout is one of the two most talked about issues on PriusChat. If you didn't find anything about it, go back and look again. Search works well.

This is an issue with most Nav systems. The problem comes from the way street addresses are assigned. There is no correlation between street addresses and physical addresses. Generally Nav databases know the street addresses for road intersections and major points of interest. Other street addresses are interpolated by taking the end point addresses and dividing them equally over the street. Sometimes this works well, and other times it misses completely.

From the Navi manual: “Some functions may become inoperable when driving. Unavailable touch screen buttons are dimmed. Only when the vehicle is not moving, can the destination and route selection be done.” Are you KIDDING ME ? I have to stop on the side of the highway to have the PASSENGER enter a destination, re-route my trip or lookup POI for gas, restaurants or hotels ? How come I don't see this problem ANYWHERE on these forums? Thats absolutely RIDICULOUS !!! Luckily I took my trusty old Garmin with us and that save the day, but after spending couple grand on the NAVI system that does not work while moving, that is a horrible workaround ! Buyers remorse already !

The other option is voice recognition. You could always learn how to input/add a destination via voice.

agreed. POI's are accessible by steering voice commands. have used them while driving many many times.

I was really debating whether or not to get the navigation because I am pretty good at geography myself (I got to "state" level geography bee in 8th grade haha) but I got it because I wanted the solar roof package on my Prius III. On my latest road trip I drove from Los Angeles to Sedona, AZ and used the voice commands to find my route. It was incredibly easy and took less than a minute. I was hesitant about trying it out because I prefer to just use the touch-screen, but I was still very impressed by how accurate and smooth the whole voice commands process was. Yes, the system did overestimate the amount of time it would take to reach Sedona, but the remaining mileage was correct. By the time we got into town, it was very dark (and Sedona has very, very few streetlights). The navigation saved our butts looking for our hotel, so altogether, I am one happy customer.

Hmm,
I thought the 2010 Prius navi would be better with the live traffic.
Is there live traffic on the GenII?

The reason your system didn't estimate the time right is because your detailed NAV settings are probably wrong. They need to be set at 25 residental, 45 main streets, and probably 65 or 70 freeway BUT when you have a long trip planned and know you'll probably do 75 or more, re-set the freeway speed setting to be more accurate.

No LIVE traffic on my gen II ... or anyone else's from factory but live traffic and detailed settings for average speed on road types are not connected.....

The 25/45 settings don't seem to work well for me. The problem is the nav thinks a lot of 2 lane highways are main streets. If I'm in Nevada for example where the speed limit is 70 on most 2 lane highways it's way off and I need to reset it. But when I return to Oregon where the speed limit is 55 (out of town) I need to stop and reset the main street speed again. My portable Garmin knows and even displays the speed limit. It may get one wrong ocassionally if the limit has changed but it's correct almost all the time.

This is another very useful feature that Toyota should include in their nav system. I like the bigger screen and the way the freeway information is displayed by the Toyota system.

Yeah I was thinking about correcting the average drive speed for different street types, but honestly, when I do long distance trips I just mentally divide the total mileage by 60 to get the approximate hours and minutes it'll take. I know I drive faster (usually 75 to 85 depending on speed limits) but I figure I might stop, eat, etc. Thanks for the advice, though!
