I paid the extra like 20 bucks to get the model with lifetime maps and traffic .
Tho I do have to remember to bring it in the house and update it .. where as the iphone auto updates.

Get Navigon off of Installous. Free and requires no internet/data.
no issues here w/ ios6 and i'm still sporting a 3GS. Granted I don't get turn by turn but just drove around the block and it works fine. Slightly better interface IMHO.
I'll be getting a iphone5 once the hype/drama die down in about a month (and verify no antena issues)
