Most metro cities will have no problem with the Navs. I worked on the Nav system and read the booklet for a few hours today and will spend much more time I read that Navteq may offer a disc for it - I'd jump on it - the navteq online store wasn't loading today. PriusChat is the one of the largest privately-owned car forums left on the internet. The navigation system truly really does Suck. It's definitely cheaper to keep a Garmin updated, but I don't personally find it easier to use than the Denso nav unit.
Any links to How To Videos or anything of that sort would be great. They just guesstimate based on standard block and lot size. They have all been very maintenance and trouble free for me. I really like the car otherwise, at least for the short time I've had it. The extra lanes have been built over the last few years. I'm planning on moving to California in a few years and having an integrated, dependable Navigation system is important to me.
Garmins and aftermarkets have the advantage that they can be updated readily and at a reduced cost. Their disadvantage is their smaller screen size and theft worthiness. It is a major highway and is 4 lanes at least 60% of the way! I just bought a 2010 Prius with the navigation option, complete with 2009 maps. I love new technology so was really looking forward to it. .
If a phone can be as accurate as I've found mine to be, I'm really surprised that a dedicated navigation system can be so aweful. Some newer software may also have a choice for least fuel use. Either solution is a lot less expensive than the built-in Prius unit. It is helpful for the rest of us to hear this, as difficult as it may be for you! It actually takes less then a half hour. Incidentally, I still use my iPod referencing your username almost daily.
Many people have lauded the 660, but it doesn't guarantee the user interface will be easy! In my mind there was no comparison between the two--the Garmin far exceeds the integrated Prius Nav in terms of accuracy and ease of use. Once my new Prius arrives, I'll have to find a good mounting solution, maybe behind the steering wheel as the previous poster suggested. And yes, I do happen to have a Garmin. My wife has a Tom Tom and loves it too. Perhaps the new 2010 Nav requires a learning curve that differs from the '07 Nav? And the inaccuracy of the maps to boot.
My hope is that he'll find there are adjustments he can make to the new Nav system so that it will work as well better, hopefully! I've been really happy with Verizon Navigator on my Blackberry Storm. I checked the three route choices and chose the best one. Remove the fuse with the pull- stepI4 stepI4 out tool. Some newer software may also have a choice for least fuel use. It actually takes less then a half hour. The amperage rating can be found on the fuse box lid. Now it's only half full again.
My experience using my friend's integrated Nav in her Prius was horrible. I traded in a 2006 Prius whose navigation had much better acuity. Maybe I'll make a cradle for it if I can't find one on the market. Sorry to ramble but I haven't quite settled down yet. No old Lewiston grade for 30 years - since renovation, still there but only used for sightseers, great for motorcycles, and the occasional scenic drive. Make sure your Nav is set as you want. We also have a Garmin 660, and it has tremendous capabilities and features, but my wife has difficulty using it.
Neither my Garmin nor my Hycam can pinpoint my house by address, due to being on an odd short block. I think all of them should have a factory recall and upgrade with a hard drive and more reliable maps and more Garmin-like features. I picked up my 2010 Prius today and am Very disappointed in its navigation system. I use it in my own car as well as in rental cars when I travel. I am pretty mechanically inclined and can fix most things so would at least try to attempt this.
