Default Navigation System

I just received delivery last week of my 2007 Prius Touring with package #6. I am initially disappointed with the Navigation System. I previously used a Garmin 2620 in my 2003 Saturn L300 that was replaced by my new Prius.

I am finding the Prius NAV does not give turn-by-turn directions for many locations that were properly recognized by the Garmin. Also, I am finding the Prius NAV cannot locate some residential addresses on minor streets that were properly recognized by the Garmin.

I was quite surprized yesterday when a rural address was recognized as a destination. But, when I had to turn off the main road to get there, the final portion of the route was not displayed nor were there turn-by-turn directions from there on to the destination. My Garmin had no problem with any of these same difficulties with the Prius NAV.

Any thoughts or comments? Thanks.

Yeah, their database leaves something to be desired, for sure.

They obviously assumed that most people would live in the big city and not notice that everywhere else their NAV system gets lost if they venture more than 100 yards from the highway. It puzzles me also, it knows the address, displays the road on the screen, but can't tell me how to turn to get there.

I'm dissapointed that the ETA isn't calculated using your actual velocity.

I get the light blue lines going to areas that aren't main roads around my home. And these days, its more suburban than rural.

Default Nav system

Someone once told me that the Prius Nav system gets the address data from the satellite 911 grid. Every 75 feet is a new address. Where I live - small Southern town - the homes have large lots. The Prius can't get within a block of my house. While in Bossier City, LA last year, when I turned off the interstate, the nav system quit, no data available. Fortunately, I could see the hotel from the interstate I mentioned that to the hotel manager & he told me that this little section of town wasn't on the 911 grid system.
With all that, it usually will get you to within a block of your destination. It is pretty educational when I select "shortest" route and drive on unpaved county roads etc. I've seen a lot of the Southeast USA by using that feature. Once my wife accidentaly hit the "avoid interstate highways" key. That was a really strange trip, until I figured out what had happened.

I had a similar experience with the "avoid toll roads" option turned on, I think by default. I was driving across the country, completely using the nav for guidance. I approached Chicago on I-80 and it had me get off the interstate. I thought it was a short cut. I drove about 40 miles on surface streets, constantly passing entrances to I-80. I finally pulled over and looked at the options and fixed it. We have no toll roads where I live (San Jose) and I never thought that I-80 would become one all of a sudden like that.

Redwein, think of it as mandatory FasTrak! In Orange County they have a few toll roads, quite a pain.. but can also be quite beneficial.

When I was in Florida, they have the turnpike (fancy name for a toll road highway) and a regular highway, that run parallel along the coast a few miles away form each other. It helps offset traffic if one is congested, but like anything, has its pros and cons. I particularly hated having to wait at the toll booths, particularly since I didnt have their "fast pass" since I was in a car rental. Waste of time..

I didn't think interstates were allowed to have tolls.

When I visited NY a few years ago and travelled from NYC to Lake George region twice, I too wished I had EZ-Pass.
Rental companies should rent them. I think it would be easy. They put your credit-card info in the EZ-Pass database for that transponder, register the plate of the car you are renting on the transponder, and that's it. When you return the car with the box, they take the CC off and put theirs back on, with maybe a small deposit withheld on your CC in case some tolls aren't posted on the day you return your car.

I don't believe the NAV system uses the 911 grid. The map data is from NAVTech, and I believe the POI is from... Oh heck, I forget the name, one of the online business databases.

Interestingly today, I set POI to gas stations since I was getting low on gas. I knew what station I was targetting. Several stations on the way were not on the map, and a few I knew were in business for several years, particularly the chevron station I filled up at. I suspected the NAV may have developed a problem, as I don't recall seeing ANY gas stations on the way to the one I stopped at.

Doesn't the business database only have the address for the businesses? The 911 grid could be used for turning the address into GPS coordinates.

That's a possibility.

But I do know these databases have been available for 15 years now, as they were available when I worked for the county, and we tried to use a map program to locate addresses to assist dispatching animal control officers. The roads themselves had tons of errors. And they did have 911 as far as that around here. The maps should be way more accurate for address->coordinate by now.

And the area around my home, outside of the major roads, cease providing turn-turn guidance. And we do have E911.
