I saw on a Cadillac forum that Nav disk updates are $500 to $1000. Has anyone priced the Corvette Nav disk update, or is there one yet?

There isn't one yet.

 

If they are anywhere near that much money, I will be seriously pissed. It doesn't cost them anymore to burn the upgrades for current owners when they have to do the upgrades anyway to stay current.

I only got nav on my car because of the deal I came across with a car that had it. I'm not sure if I would buy nav again or not (not likely, for other reasons), but the cost of the upgrades would certainly put any thoughts of buying it again out of the question.

 

The latest European version cost $345. European disks are usually more than the US ones. I believe that they will fall in line with the rest of the GPS updates. Garmin charges about $300 for thiers' and BMW charges $360.

 

GM should make sure your home is listed and not in the middle of a blank space when they sell you the NAVI system.

 

391.00 plus tax check with your local dealer

 

Not true, BMW charges $199 for the Navtech update DVD. You also have to realize, you may not notice any new "changes" unless your city or (that you're using nav on) town had some MAJOR road changes in the last year or two.

Has anyone tried to make a backup dvd? Does it work? Backups work fine on the E60 BMW. I don't like using the original since the disk may warp or get scratched if I use it too often.

 

I think infiniti charges 150.00. 391 is kinda outrageous

 

Yes I made a backup disc for my 04 SRX nav disc. The list price was something like $500 to replace it if I lost it. Purchased a double sided double density disc. Had to burn it on a newer dvd recorder at my neighbors house. Now I use the copy in the car and keep the original with my other car documents.

I don't have nav on my c6 but someone should try this: I got a code for setup that I punch in when I start the car... can watch dvd movies while I drive... kids in back seat can see fine. Usually just watch the occasional dvd music video and keep my eyes on road most of the time. Not sure if this would apply to the vette nav but the code was provided to my by an installer at FutureShop who said he just got it off the web.

Anyone try this??

 

I set home by "map" when I was in the driveway.

I have never had a map system get my home in the correct area on my street. It curve very hard just before getting to my house so the lat/long for the street is all wrong.

Interestingly, my house number is 4123 (odd) and 4124 (even) is about two blocks away (big 1+acre lots on a tight curving road.)

Go figure; use the map and you'll get pinpoint accuracy instead of dirt.

ps - if you live in subdivision that was built in the last three years your roads are likely not on the NAV/DVD - or so they told me!

 

My dealer charges $200 for the C6 updates.

 

I wonder how much more accurate any update will be especially if only one year or two years newer than the one which comes with the car.

Today the system was great and awful. It brought me exactly to a location from over 40 miles away. Great, almost amazing.

But then later the same day it thought a County Road ended and magically then reappeared 3 miles later. Due to the inaccuracy it told me to turn off the county road (since it seemed to believe it ended as indicated by the map), told me to drive a mile out of the way, then took me down a dead end residential street which it thought would get me to a major highway. Just for kicks I drove down the residential street and actually it appeared that at lest 10 years or more ago it might have actually connected to the main highway but was turned into a dead end when the main highway was reworked. When I turned back and drove back to the county road I looked at the map it was displaying and verified it just plain thought the county road had ended. When I turned on the county road it was confused as I was driving in an uncharted area of the map. I have driven on that country road over 20 years ago and it is in the same spot it has always been.

Furthermore my residence is in a neighborhood which was created over 12 years ago. I have never seen it accurately depicted on any online map system such as mapquest, mapblast, google, etc. The same is true with this map system as well. My street typically does not even exist.

I know it is a big country, and new roads are created everyday while others are changed. I have no idea how these people add streets into their systems. It must be difficult to be accurate in the mapping business. But I would think major county roads which have been around for 20+ years would be accurate, and residential streets which have been around for 10+ years would be accurate.

Since nobody can get these things correct, I highly question the need to spend that kind of dough on a new map every year or two as I just don't believe they are going to be radically more accurate than the ones we are using now.

Maybe when Navigation systems are standard on most cars, or are perhaps a $300 option which everyone orders the maps will become more accurate as more and more people complain about being sent down a dead end road or can't find their buddies house in a neighborhood created 12 years ago.

End of rant.

 

Kerbeck had told me that map updates were 200 dollars if you wanted them. I don't think I'll get any for a few years. It doesn't make sense to get one every year since the roads don't change that much in a year.

 

There are situiations where the Navigation is not to be trusted. I recently attended a High Performance Driving Event at Summit Point Raceway in West Virginia. I tried to use the Nav system to get me home.. led me into a dead end which looked more like a path than a road.

This is unfortunate since the more remote the area the more you would like to be able to trust the Nav. I guess for now at least nothing replaces a current hard copy map!

 

How old is the one that came with the car, and how recent is the update time between the two? If I'm going to an unfamiliar place, I'' do a Mapquest or Google for backup. It has saved me a few times.

 

That's a good deal, but down here in FL they really need to update and ADD a lot of info! There's a lot of missing streets - old and new. The first time I got a little ticked with the NAV (I love it BTW) was up in KY during the Cruise In this year (YES, I went and they won't put it under my avatar ) when we went to the drag races. I didn't know how to get to the park... Left a little after everyone else so I punched in my point of interest (the drag strip park) and it gave me a routing/time/etc.. Drove to the end of the guidance line and it says "Further driving info is not available from this point" WTF! Luckily there were a lot of other Vettes heading there that I just followed, but man when it said that I was just sitting there looking at my car's symbol on the screen out in the middle of a roadless map page!

Looking forward to the new updates

 

I'd assume that the one that came with my care (Build June 9) was either a 2005 or 2004. They release a new one every year. I'm not sure when the new ones come out though.

 

I have a Garmin Quest that uses Mapsource information. The downloads are free. I just wonder when and if we will be able to find something for the Denso unit in the C6 that will work or can be made to work and that has more accurate data. As mentioned above, the data is old and I suspect that one year of updates will not improve matters a great deal.

Like was mentioned above, my C6 nav unit turns me loose about a mile and a half from home saying detailed info not available for this location...even though the roads show on the screen!!!
I used the map to set the home point.

I know that some will say that I ought to know the way home, but the indication to me is that I might want to have directions with me every unknown place I go in the C6 as I might get "turned loose" a mile or two from the destination.

The little Quest unit on the other hand with the Mapsource data is not perfect, but takes me through the development in which I live directly to my residence.
On a trip this weekend in another car, the Quest led me flawlessly through the Catskills of NY, the City Boston, around NY city, and generally everywhere I wanted to go. I did not have a paper map in the car for these areas. I felt I would not need them. The downside is that I have to have a laptop along as the unit in the car is limited in the info it can store at any given time. These downloads are quck and easy and can usually cover anywhere I might go in a days drive.

Maybe someone sharper than I can figure some code or find some aftermarket DVD that will contain beter data than the Denso.
