Darren, not sure you were the last in our area. I didn't get the update until Oct 29. The 6.0 update thread shows first downloads started Sept 11 last year, so it took almost 7 weeks for me to receive the update.
It has gotten humorous watching the forum at each new software update. As the number of new owners increases, so do the number of comments about who gets it first, does it come on wi-fi or 3G, do I need to be plugged in, does the car need to face the north, is Canada getting it before the U.S., how do I sign up for beta, can I get it at the service center, I just got my car from the service center and still have the old version, etc etc.
The main thing I've learned in almost 16 months of ownership and several software updates is that you will get it when you get it, and there is no pattern.
