On the station names I can only guess that it was cut out because other warning stuff on the EU version not supported in OZ. It was probably easer to cut the lot out rather than just remove some functions.
On SUNA, In Sydney it quite good but don't expect it to magically give you clear roads. Peak hour is still peak hour.
What I have noticed it is not reporting slow traffic if it is not abnormal. As an example I the M5 is useless toll road expect to often be doing under 60 in a 110 zone. SUNA wont report that because that is normal. If it was down to say 40 (an abnormal speed) expect to see a warning
As another example I was driving to the northern beaches of Sydney today. From where I was you could go via the spit or around Northbridge. Now which ever way you go your stuck getting around the waterways if you hit traffic. No chance of going another way. Normally I'd go via the spit which is the way the AVIC also routes you. Along the way (in the harbor tunnel) TMC received an accident report and routed me the other way around with a nice “accident ahead re-routing†message. As one of my guys also was going to the same place in another car I thought give this a go. I got their 25min ahead of him. Not that that really proves anything but I did not encounter abnormal traffic along the way and the others were in bumper to bumper getting around the accident
Cheers
