I went to dinner with a neighbor 2 nights ago and we used the NAV in his Acura TL (one of the most highly regarded NAV systems out there and the one that is most frequently used as the standard) and it too had difficulty with streets that weren't in his DB. He also said it some times suggests "wacky routings" that he ignores and within a few minutes it "re-calculates" the route and all is well.

I too have found that by ZOOMING in, it has much more granularity with regards to street displays.

My guess is these systems are about a 90% solution and there is no Holy Grail of NAV systems.

My experience has been pretty good however it NEVER directs me to take any highways. In fact I might be on the highway and it always tells me to get off the next exit and has me taking the back streets or back roads or something. I mean it gets me to the right destination but seems to take a longer route. Anybody know why it always directs you OFF a major higway???

 

Nav is cool even with its quirks.

 

Built-in nav was one of the reasons we bought the C6. It's far better than no nav at all, and the integration features are something that an aftermarket unit couldn't have. But overall, it's a second-rate unit compared to the one in my wife's Toyota. Hmmm... Toyota stuff better than GM? Why am I not surprised?

 

Again, I should leave this to the experts since I have no built in Nav myself, but perhaps there is an option you need to adjust? On my Garmin, it lets me set my 'style' of prefered route and what to specifically avoid -- toll roads? avoid hiways? unpaved? etc. It also has an option to learn my preferences as it goes.

 

This is why I did not choose this option

 

Sorry to hear of your grim misfortune. This is as bad as not having feet. Redding? Horrible,just horrible. Oh,the humanity...

 

I wonder if there is a way to hack the NAV unit so that you can make destination changes while on the fly?? I'm sure with all the teckies out there, someone should be able to.

 

Greetings

I am interrested in a factory NAV. Do you have a price in mind. I would need the nav head unit, DVD and antenna.

regards

 

You are correct about absolutely great nav in Cali. I have the stock nav unit also and it worked tremendously in California. Now I am stationed in Mississippi and the nav is far, far, less than stellar. Half the time it shows that I am not even on a road when I am on a major highway. I just think some of the po-dunk states (ie me in MS), are not mapped very well because half the people here can't even spell GPS much less use it. Although I do love my nav when not in MS.

 

Thank you all for your response. What makes this a disappointing unit is because this is my first car with it. I have used systems in rental cars and my sons Lexus (GREAT UNIT, altitude, BIG db, adjust on the fly, etc). When I know where I’m going and it does weird thinks, how can I trust it when I’m in BFE? Why would I think that GM would allow such an inferior unit in a Corvette? NORTY why don’t you like Redding? I took delivery of my 06, C6 in Oct 05. TrackNoob how do I update on line? Thanks

 

Mine works PERFECT. I even moved to a new street that wasn't in the system. And my dealership up graded it for free. I have an after market one on my wife car. And I wouldn't give you a penny for it. I love the one on my C6.

 

My car came with a little extra booklet about the nav system mapping, it discussed detailed-coverage vs non-detailed-coverage areas. Huge areas of the U.S. are non-detailed. When driving there, sometimes it shows the streets but not the names, sometimes gives just a few of the names, sometimes just a few of the streets, sometimes shows streets but the navchick announces "step by step directions are not available in this area." I had it turn me the wrong way down a one-way street (one-way sign was hard to see), as soon as i made the turn the navchick said "sorry, guidance not available in this area."
I told her I expected a, uh, favor for what she'd done, but she ignored me.

 

Anyone know how to get the updates? Two come with the car purchase.

 

you can adjust brightness and contrast.

 

I've been doing a lot of hacking on the C6 nav trying to find hidden features and with some help, I managed to uncover the three access codes in my avatar.

I've found that most of the systems out there, be it the uber-cool Pioneer AVIC series, the Toyota/Lexus systems, the Acura systems, the Chevrolet systems, the Audi systems, the Land Rover systems, and too many others to mention all use the same "base" for their software.

When you're actually mucking around in the binaries, all of these systems look remarkably similar, even though there are significant differences. Denso provides the base "skeleton" if you will, and then it's up to the manufacturer to determine which features it's going to impliment and how. For instance, it appears that the "hooks" are there for our nav systems to play DVDs, but if the actual code is in there anywhere, it's offloaded onto other chips -- the Lexus systems have it built right in to the main program, along with all the climate controls.

There are a few manufacturers, like Infiniti that use a different system, and I think Garmin has their own propriatary format, but they are in the minority. The KIWI formatted maps that Denso uses tend to be the most comprehensive, but just because they update doesn't mean that GM is going to license the latest maps or release an update.

Currently, I'm working on trying to make "hybrid" discs to see if I we can use the map data from other manufacturers. However, getting access to the discs isn't the easiest thing in the world.

 

I love my vet, but yes the nav does suck. The route selection always takes me the long way, but since I am in a vet that’s okay. I have a Tom Tom that I use in my other car and that works a lot better with nicer graphics. P.S. the touch scene with the Corvette logo makes it worth it for me.

 

I didn't order the Nav either, i just don't find it that useful.https://www.corvetteforum.com/forums...lies/crazy.gif

 

Surprised no one stepped up yet to answer this - it's in the Route Preferences. You undoubtably have the Allow Major Roads (or whatever it's called) turned off.

HTH

 

I've used several systems/applications - HP NAVTEQ, Delomre and Microsoft - they all suffer from the same short comings to some extent. Those of us who can ead a map some times find the directions of the system down right dumb - if not outdated. Tahke the G Bush (Sr) from Fort Worth to Dallas and your Vette is a BOAT! I believe the issue is one of updates - WHEN WILL GM ISSUE THE NEXT UPDATE FOR THOSE WITH 2005'S???? BTW there is a software update (6-9 months old) to let the CD read/play MP3s
