The *Link systems found in the "down-market" name plates that GM has are all similar to one another, but they aren't similar to the CUE system in the Caddies. No haptic technology. Buttons and ***** where they should exist, and touch-screen tech for other things.
Very different systems.

IIRC, the C6 system didn't get updated because after a few years, GM switched to different communications busses on their other cars. So an update to the C6 would have required re-designing the electronics in the C6, or developing a new unit for just that model. Either method would have been prohibitively expensive, so nothing changed.
If the C7 electronic system remains compatible with other GM cars in the future, a change would be relatively easy. Whether or not they will do it, is unknown.
And newer is not necessarily better, we have a pair of Toyota Camrys (2005 and 2011), I prefer the Nav in the '05 over the '11.

Paul your last sentence is very revealing. That is the main reason why the C7 Nav system will be obsolete just as quickly as the C6 system was. It may be all flashy now but it is a given that it will quickly become obsolete. I can't see that GM or any of the other domestic manufacturers are going to keep updating the technology for a given vehicle. It never has. I am very confident that the C7 Nav will stay exactly the same for the duration of its run until the C8 is released. For that reason alone I would advise against getting the Nav system unless you don't mind paying a premium for what will soon be old technology.
You're really having fun trolling on here aren't you?
If you read, the C6 was scheduled for an update but because of restructuring, that didn't happen.

Believe what you want. I have nothing to prove to you. The communication bus has nothing to do with the intrinsic functions of the Nav system. They could have changed the software easily to provide more features. If you recall it was a simple CD load to make the 2005 Nav system play mp3. The C7 Nav system will end up being an antique just like it was in the C6. This is something I would not order in a C7.

I believe b4i4getit has a point... I'm a software developer and I can tell you that the higher-level functions of the Nav software could have been updated without affecting the lower-level hardware stuff that the CAN bus would interface with.
What MAY have been a factor, though, is processing power and memory. That requires a hardware upgrade.
Regardless, I think there could have definitely been a software update.

While I like the nav in smart phones or stand alone nav devices, I prefer the integration of the factory nav systems.
Also, once you arrive at a certain level of screen resolution and graphical sophistication, further improvement become less and less noticeable. Maybe this will bode well for those who prefer the integration of a factory system to the less well integrated (but lower cost and likely more advanced) standalone or smart phone based systems.

I can't justify the cost when my smart phone has google maps with free updates. My Garmin too. Plus, I'll be darned if I'm going to pay a dealer for updates.

Gawd knows but they need soemthing like my Z. You could go to the dealer and pay something like $300 and get the new maps installed on the HD. OR, you could buy the CDs online and following the software install instructions for $199. And I missed a sale on them once for $179.
It took me about an hour and 15 minutes.

I hope the C7 NAV unit is as good as mine now--I won't whine at all (and mine is from 2010).

GM released an API for the newer cars so you can write your own apps to run on the headunit.
