that's a good question on any design changes in 08... not sure..

on the software updates.... yes they can do them...but they are usually reluctant to do so... thing takes hours to perform... and they're always backed up...

doesn't hurt to ask around the next time you visit the dealer on any known issues or info on any design changes for 08.. (try to make friends with some of the mechanics there...)

i do..
