for those that use the OEM NAV it's a good deal.
Update is compatible with 2016 - 2018 Corvettes

A couple years ago a friend's '14 couldn't find Lambeau Field in Green Bay, WI (home of the Green Bay Packers which opened in 1957). My 2017 could find it so I'll probably update mine sometime before I've had it 60 years so it will have relevant information. ;-)

Hey dude, I just wanted to know what kinds of failures you got. I wasn't looking for "enough fails". Why did you assume that?

I'm sorry it failed for you. All I can say is that I've never experienced that but mapping data is subject to human error so all systems could have problems.

I'm a bit confused when you say "While using vehicles GPS, takes me past address, u-turn, states I have arrived". What is "using vehicles GPS"? Do you mean using the factory nav? I don't think can tell AA to use the vehicles GPS - I believe it always uses the phones GPS signal. Also, if "vehicle's GPS" == "factory nav" then is this an admission that the factory nav failed?

Additionally, I don't understand what you mean when you say "In this case the phone was correct". Do you mean AA/GM?

Finally "On way to basketball game downtown LA, phone GPS decides it no longer wishes to provide spoken directions. In this case vehicle GPs for the win" - you do realize that GPS and spoken directions are two totally separate and distinct things. One is talking to a bunch of satellites in the sky and the other is talking through your car's speakers. Are you sure you just didn't turn off voice?

> in this day and age, why wouldn't you have an unlimited data plan?

Personally, because I can't justify the cost.

My prepaid plan cost me 12$/month. minutes roll over (I have more than 5000 unused minutes)
screentime says I use my phone < 20 minutes / day (usually on a game that requires no data.)

At that rate, I can barely justify the phone

Most places I carry my phone provide wi-fi, so if I really need data, I connect that way.


Whats an average unlimited plan now - (at least) 45/month?
30$ price differential....About 1800 over the span I've owned the car...

So what I didn't spend on an unneeded unlimited data plan more than paid for
the Nav system, the map update, the phone itself, and 5 years of service on that phone.. .

And I'm still money ahead.

What seems strange to me, is our NAV is run via SD Card... Not USB ?

The factory nav does not run via SD card. Where did you get that idea?

There is an SD card that plugs into a slot to the left INSIDE the glove box that is for the PDR. AFAIK there is no SD card slot in the console, though there is a USB port in the console and another behind the screen. Neither of these is "for the Nav" but when you update the Nav you use one of those slots to upload the changes. I believe your salesman is mistaken.

Here's an interesting, simple and quick test you can perform on your own. Take it out! Can you still nav?

What year is your C7? Because I believe the 14's (and maybe the 15's) had this SD Card thingy in the center console but they stopped doing that. I have a 16 and I don't have it. In any event that SD Card is not required for the operation of the Nav (at least as I have heard it) and again if you popped that SD Card out then try to use the nav I'd betcha it still navigates.

I think that SD Card is either for music or perhaps the PDR. I think it later moved to on the left side of the glove box when opened. I've only had an SD Card in the glove box area for use with the PDR. Does anybody know if I can put music on it and use it from the glove box slot?

When you take that SD Card out stick it in your computer. Many computers have slots for such cards and an SD Card -> USB thingy is like a few bucks. I betcha you'll find just plain old MP3 files if anything is on it at all.

Ecit: I got curious so I looked it up. From 2014 Chevrolet Corvette Infotainment System, page 21:

Audio Players

USB Port

This vehicle is equipped with one SD card reader and three USB ports. The SD card reader and two USB ports are in the center console. The other USB port is in the storage area behind the radio display screen. The system is optimized to support two connected devices with a total of 100,000 songs.
And on page 25:

SD Card Reader

This vehicle has an SD card reader in the center console. Set up the SD card while the vehicle is in P (Park). See “Audio” under Using the System on page 8. Place the card into the port. If an SD card has already been connected, but a different source is currently active, press the MEDIA screen button to scroll through the audio source screens until SD card displays. Press the SD source menu to display the SD card options such as play/pause and previous or reverse. These same options are described earlier for the USB menu source. See USB Port on page 21. This vehicle may also have an SD card reader in the glove box.

My '14 was still on the original maps when I bought it in November. Got an offer from GM to update the maps for $99 and I decided to go for it. Easy install, and I do believe that the Nav system works better with the update.

Yeah, its a 14. You're probably right then. I did pull it and NAV works. Probably for either PDR or perhaps tunes.
Thanks for helping me work it out !

Sure but it got me thinking... As a software engineer, I can get an sd card with 64 or 128 gigs. Surely the mapping data isn't that big! Why shouldn't a map update be a mere, replace your old sd card with this new mapping data? Because sd cards are slow? Surely you could transfer the relevant, within say 100 miles, of mapping data into memory in the head unit quick enough. Sounds like the GM engineers weren't thinking that much... Then again, maybe they just didn't think they could sell ya an sd card for $100...

2014 had an SD slot in the center console. It had nothing to do with navigation, and PDR wasn't available in '14 at all.
2015 had SD in the center console, and a second, dedicated SD in the glovebox for PDR.
2016 and up got rid of the center console SD. PDR SD is in the glovebox.

GM started doing that with some of the redesigned 2019 cars. Nav runs off SD. C7 is not included in that list. I think the RPO for SD based Nav systems is IOT. C8 will get that system.

For what it's worth, IO6 nav systems have 32 GB of on-board flash memory. That also accommodates a couple gigs for the infotainment operating system. The nav data sits on a ~22 GB partition.

Non-nav IO5 systems get by with 8 GB of flash memory.

There's you're problem right there. Considering the very limited set of functionality that the infotainment system performs, having it that big is a sure sign of totally crappy design.
