Really? What do you call this: chopped liver? You have this genuine Holden unit in Oz for ~ $1600US.
You can even have turn-by-turn mono voice units fitted to the central MFD unit:
Again, you're misleading people with negative untruths. Terrible case of Not Invented Here syndrome with everything you post about the VE/G8.
Holden had Satnav available in Australia within weeks of launch of VE in 2006 - it's a common unit used in cars in Europe and Asia in a similar position. The US plays by it's own rules like with crash safety, GSM mobile phones and so many other areas - not Holden's fault.
Holden puts whatever GM US tells them to in the cars. They sell Satnavs in a trickle here, so presumably they're that's same everywhere. It is not as big a dealbreaker as probably the lack of manual trans on the V6 and GT.
The Commodore may not be a perfect 'world car'. Fine. Name a GM America car able to be sold in as many markets? Other than the CTS which is currently in three/four of the five/six the Commodore is, there is none.
Nearly all the people on this board who complain about Satnav availability would never ever consider a RWD muscle sedan in the first place.
