08 maps are perfectly ok, used myself & was in slovenia month or so ago.
TomTom have more interactive updating system where as the audi solution is a hardware solution that cant be updated as easily without creating many dvd's a year which people just dont really need or will buy, pity they dont get there butt in gear more for technology as its a revenue stream that can be taken advantage of if they can utilise wireless systems or internet to update cars nav maps via a subsciprtion etc, but alas audi & technology dont usually stay up with eachother, they do seem slow tbh at implementing newer tech which is very annoying.
