After reading that report I can be thankful my Chinese unit does not display some of those faults , whilst it does not give spoken street names it is pretty damn accurate with placement , I can say with all honesty it has not made me turn before or after I am supposed to LOL , it will tell you to turn in 300 metres so I now can judge 300 metres for myself to know which one .
Mapping is very up to date as it has the new Brisbane Airport link tunnel in it before it actually opened amazing ! There is a guy on VW Facebook page with a Tourag that does not have that tunnel or the Clem 7 which has been open for around two years plus and its a 2012 model he is pretty pissed as the unit was a $3500 option . I am still finding things in my units GPS that I did not know about you touch the screen and a new menu page opens up but I am too busy to use half its functions . The software is IGO NAVNGO with WhereIS mapping . and for a paltry all up price of $380 for the whole thing with Digital TV Bluetooth and so on .
