Happened to me for the first time last week.

Thanks for the help

Mine has done this a few times as well. It's nice to know there's a fix.

I have an appointment with my dealer to get the update. Even though I am now out of warranty, the problem was documented during my warranty period; the dealer said they would take care of it.

It seems the new GM is more customer service oriented. I am impressed with Chevrolet Customer Service; they contacted me after reading my post here in the forum.

LOUSVETTE

Did you ever get the update?

I'm curious on this as well as my '06 has done the same. Obviously a long shot but is there any way an every day Joe can order (or even longer shot - download) this disc to update ourselves?

LOUSVETTE

Went to the Chevy dealer yesterday and they did the software update. Time will tell if that fixes that sporadic problem.

What a coincidence. Both exact issues happened to me today! Nav screen shutoff AND left Bose speaker pops! Chances are the two may be related. For me the screen shutoff issue happened first.

I found a workaround for the screen issue was to say the voice command "screen off", wait for the acknowledgement, and then press the NAV button which turns on the screen.

Thanks for the service bulletin information. Hopefully I'll get this applied while they replace the speaker ...

I have a 2008 coupe with 3 months remaining on the factory waranty.

I've had the same problem lately with my 07 Coupe. Most times, comes back to life on next restart of car, but that also failed today. By coincidence, noticed that the window indexing was off. So re-indexed the windows and then restarted the car - nav came back on.

Don't know if it's related, especially given the TSB, but thought I'd pass along.

Dealer did the bulletin on my car last week, it took them a while to get the update disc in 'cause they had lost their original.

Everything working normally so far, but it hasn't been below freezing in our garage yet this winter.

I've had similar issues with my 2007 which is out of warranty. Anyone know what the cost is to have the fix applied?

Thanks for the great information...yesterday started my 2010 GS with 1900 miles on it after 3 weeks parked and no screen (same indications as above posts)...restarted no fix, drove to Lowes, came out, started...working fine. Will take to dealer for radio software fix.

My 2010 GS 10,000 miles has the same problem. Blank Nav/Radio screen. I'll have to call the dealer to arrange an update too.

Grrrr, ditto, after my 2010 GS sits for awhile, which has been common here the last few months of monsoon rain, the screen is blank on start up. Shut the car off and restart and it is fine and is fine the rest of the day I drive the car.

I will see if my dealer can do this update hopefully while I wait if they let me schedule an appointment. They will have to apply this update on my word, should know my customer service level shortly pending how this pans out. I am glad it is an easy fix if the software does the trick.

Ideally I wish I could get my hands on the update file to burn a cd and just do it myself and save the trip.

This thread will probably be locked pretty soon because of age, but our nav screen worked fine for the dozen or so times I started it in cold weather this year.

Red89gt

Thank you Jim.
Hopefully the thread won't get locked as I used the search and found the exact condition I am dealing with in my car. Wondering if anyone else that posted on here had success with the new update?

good morning, i hope you can help me. i have a 2007 c6. the nav screen is blank. everything works, just cant see the screen. i took it to the dealer and gave them the info that there is a update software # 09-08-44-019. and the TSB on this #09080844019. they told me they cant locate the disc and that it is obsolete and they said they dont know what else to tell me. i have a buyer for this car. and a 2013 on thier lot i would like to purchase. i would think they would put a little more effort in to fixing my nav. but they are not. they said they would see what they could do and call me today. i told them to contact thier zone service director to see if he could help and he said the guy is unavailable until next week. my buyer is in georgia, the dealer is in florida and i need to get this car up to this buyer with a working nav asap. can you please help me. my direct phone is 239-895-5533. i need to tell this dealer where to get this update disc since they apparently cant seem to find one. thank you very much. my direct email is kellyhalloranrn@gmail.com

kellyhalloran,

Could you send me your information (name, number, address, VIN, current mileage, involved dealers) so I can look into this information?

Thank you,

My radio/nav unit has gone out. It doesn't come on after restating the car either. It is cold out but the car has warmed up to normal temp for a long period of time giving the unit time to get to room temp and still will not respond. I have removed the battery cable with no help too. I have also pulled the fuse to check it and still no response. With the radio system down I have no sound for car noises like when you press buttons, warnings, seat belt off and the like. Would the below freezing temps have anything to do with this problem?
