There have been many many threads in the past 2 days about people thinking they are getting notified of the 8.0 update but in fact it is an incremental 7.1 update.
I'm getting tired of typing the same thing over and over again...
So if you take a figurative step back, remember that there's no guarantee that the 8.0 rollout will happen tonight or even tomorrow. I for one am going about my usual business (which includes trying to get a good night's sleep) and whenever a software update image shows up on my car, I'll deal with it then. Sorry, I'm a bit of a party pooper, but I'll gladly live vicariously through the TMC posts of all you other crazy owners.
