Once you learn how to use the nav it works very well and has a ton if information, but you have to learn how to use it, and that's the problem with most who say they don't like it.
It contains a lot of informaton. I spent several hours learning how to use the one in my 2013 and use it all the time without problems.
As LV2TOUR indicated using memory points is the best way to program it.
I've spent a lot of time learning to use the system because I too prefer a stock look. I watched all three 20 minute tutorials on the museum web site. I've read and re-read the manual. When it won't take the street number of a 40 year old address it's just indefensible. When you come to a T intersection and it tells you to turn the wrong way it's just indefensible. When you can't input the street name but it shows on the map it's just indefensible.
You can't use a memory point it won't let you input.
My factory unit died and dealer says GM version replacement would be over 1,400.00. Even they said its wasn't worth the money. Mine is an 05 with Bose and the KenwoodI purchased was a great replacement. Fit perfect in dash, has great color and sound. Added reverse cam. Well worth the money and navigation system is in real time.

Just curious, what is the city, street name and number. PM me if you prefer.
My '13 changed time zones randomly and switched sources, lost station presets, etc. when I bought it. Fortunately it still had some warranty left and my local dealer replaced the head unit when I got it home.
I don't care what anyone says about the NAV, it sucks. It won't take perfectly valid street names even though it will display them when I drive down them. It says my work street number doesn't exist even though it's been there for 40 years. It frequently gets the direction of the last turn wrong, says left when the destination is right. I know I'm dyslexic but not that bad! I even bought the update disc this year, total waste of money. And that's just the facts, nothing about the crappy user interface or antiquated looking display. So it displays turns on the HUD, big deal since I have to turn off the G meter, the best part of the HUD.
Can't agree more, before mine broke, go down a straight road and kept saying left turn ahead, right turn ahead, etc.
I recently purchased a 2009 Vette with navigation. I don't care about the navigation as it is useless but the clock is always off by one hour. I have reset it and checked off daylight saving time as we are still in DST and it is fine until I shut the car off. When I restart it is off by an hour again. It is one hour behind. Is there a trick to keeping it on the correct time?
There have been posts about this before but no solution. The nav unit seems to lose power and then it loses its memory. It reverts to the factory settings. Eastern standard time and no saved navigation points.
Mine has been doing it off and on for over a year and it happens more when it is hot out.
I like the nav unit, have no problems udsing it, but we usually take our Garmin along also.
You may have to update the nav system with the latest factory disk and enter your area. If it still acts up more than likely it is on the verge of an internal meltdown. This happened to mine and the only fix is to replace the unit, per GM dealer, who also recommended an aftermarket unit instead of the factory replacement. Cheaper and more accurate.

I use both since they both make about the same number of mistakes on long trips. IPhone has more up to date roads but factory nav has better routing. IPhone will tell you there was an accident ahead 3 hours ago while the factory nav won't tell you anything about road conditions. When the iPhone is correct about a slow down ahead the factory nav makes it very easy to recalculate a detour. When the factory nav tries to send you down a country road the iPhone's silence tells you that isn't good. An iPhone can be "programmed by a 5 year old. The factory nav has a learning curve. The iPhone will only give you options a 5 year old will understand. The factory nav has more options than a rocket scientist would ever use.
As to your issue with setting the clock, try setting a time zone that makes the clock correct. It should then not change. The question then will be does it do daylight time correctly next month. And this is the first time I have heard of anyone having trouble with the factory nav auto clock setting with a good GPS signal and correct settings.

If these questions are answered then it usually becomes a simple matter to give instructions that solve the issue. Usually the problem starts with people entering too MUCH information because street names and numbers have to be entered exactly as the system knows them. If you keep typing instead of picking from a list you think it doesn't know. Sometimes entering the street name before the city can help. Always entering the street name before the number helps.

A newer disc won't do any updates to the nav system. The only thing on the disc is all of the map information. No system programming information is on any of them.
For those who want a less emotional comparison of the different Nav systems, here's a comparison I wrote up several years ago and it still holds true.
We've driven 140k miles over most of the USA and Canada using the factory Nav, when someone makes an aftermarket unit that will display on the HUD then I'll be ready to change. But not until then.
I got a new tip on this issue today and it looks like it may work. Set the correct time and your correct time zone, then DST if you are on DST as we are and then hit the memory save button #1 and hold until you hear the beep.
I installed an 08 navigation unit in my 08 C6 and it worked fine. I had to replace the battery and now the radio works fine but I can't reset the clock. I push the time button and it beeps, then the 12 hour time clock and it beeps, but when I push the hour or minute set nothing happens. I don't get it. Anybody?
My '05 nav unit is still going strong (knock-wood).
It has taken me all over these here United States, and never has it ever taken me to an incorrect location. There have been two times over the years that the address wasn't in the system (old disc).
Much good info upthread about actually learning the quirks of the system before calling it junk. It may actually be smarter than a lot of owners who throw up their hands w/o understanding why it's not working for them. Are the graphics old-fashioned? Sure, but keep in mind this unit is a decade and a half old tech. It still does what it's designed to do, and quite well if you bother learning it. It's not an AI, it can't learn how you work, and the fact that directions pop up on the HUD is invaluable, IMO
I've never had any problem with dates, location (other than one time on a trip (2006) it lost GPS signal, and it thought I was in the middle of Lake Michigan. About six months ago, it did quit working, saying that there was no DVD installed. I thought the system was toast, but this week, I remembered that I still had the original disc (barely used) that came with the car in the basement. I dug it out and installed it, and it's working again. The disc (2007) that I had been using was all scratched up--no wonder it wouldn't read.
I find it user unfriendly but I think its me not the unit. It has a lpt of info perhaps too much.

I have a TomTom in my daily driver and find it far more intuitive and user friendly than the Denso units in the Corvette. Unfortunately the TomTom still has its drawbacks as well. The yearly updates get to be a PITA and expensive. There is nothing more annoying than to have purchased the latest maps only to find that a freeway entrance, exit, major artery and roundabout that were completed and put into service 2 years ago are still not in the latest map release for a sizeable city.
Smartphone and WAZE.....done. It alerts you to upcoming speed traps, construction, disabled vehicles and lots more info. Free to use....no expensive updates or discs.
You can integrate it with an aftermarket head unit and with a new head unit you'll also get the benefit of better sound quality over the stock system.

There is a sticky in C6 Tech/Performance on this issue, you are not alone and it will be an increasing issue for many others shortly. Good info and will explain the issue. No fix for the Corvette yet.
