If you have to keep the Nav disc in the slot, then there is no place for a CD. Since there is only one slot in the car, I don't understand.
According to the manual, when you insert the update disc it will begin the update process (including requiring you to confirm that you want to update the system, and enter the authorization code for the disc). Once the update is completed, the disc will eject and the system will reboot.

My information demonstrates BOTH application and map database were updated.
Your map database version doesn't require updating with this release as they are identical. And your application version suggests only a minor maintenance update would be applied. I would not spend the $199 just for that.
My updates were substantial but, in all fairness to GM/Alpine, the system still operated as described in the Navigation manual prior to updating. The system operates a bit faster with no obvious new features since updating.
I tried to put my 2009 disc in the NAV, it just read it for a few seconds, then ejected the disc. No error, no prompts, or anything. I do know it needs some sort of update to resolve the nav guidance volume issue. It won't reduce the music volume when it speaks. In either case, it's still with the dealer for other issues - so they can figure it out. Perhaps the update will allow it to work correctly...
NavDisc customer service inquired of Alpine and was told that the ignition switch must not be off (causing a redo) but it may be in ACC mode for a short (undefined) time without draining the battery. The recommendation remains to run the engine for approximately three hours while updating.
So the dealer "claimed" to have updated the Nav Disc, but I knew they didn't do it even before I checked the Nav version info. But as I've recently discovered, apparently the GMNavDisc Center sent me the wrong one anyways. Even though I called them twice to question the changes in the description of the disc while it was on backorder.
Oh well. Anyways, here is the pre-update info from my CTS.
So, 3 hours to update eh? Did you guys just start up the car and let it idle in the driveway as "recommended?" Or perhaps you could leave it in ACC mode and connect a battery tender/charger directly to the battery while it's updating?
Scratch my prior message. I have since installed the update. The instruction screen of my version clearly states that if the ignition is turned off the disk will pick up from the stop point next time the ignition is turned on. This leads me to believe that there are differing instructions, depending on the production run, or build. Other versions probably warn that the ignition must not be turned off, as was the information I received from Alpine.
Finally got the correct 2009 Nav Disc update a few days ago. It also took a bit longer than the instructions indicated (4+ hours). It updated the audio, software, and map database. It did add quite a few new roads/highways around here, but didn't resolve the nav voice issue. It still tries to talk over the music that's playing without lowing the volume of the music like a normal nav system.
Very annoying. I'll have to take this up with the dealer again during my next visit...
