Just got back from a trip from Sydney to the Sunshine Coast Hinterland, gotta say bloody beautiful up there.

Had fun getting up there putting the RNS510 through it paces, according to the unit when on the Pacific Highway past Coffs Harbour I was OFFROAD and it kept on asking me to turn left (1st time into the bush and the 2nd time into the river)or please make a U turn.
I agree the maps are totally inadequate once you get out of a major city. If you relied solely on them you would be 100% lost.
The VW version is as confirmed by VW is version 1 which is equal to Version 14 of the older Sensis map 9well thats what I got anyway and it is suposed to be the latest)????
The other thing that really threw me off was its calculation of time and distance once a destination had been plotted. From the point of plotting at 4:30pm to destination was 536k travelling at 100kph should come out to approx 5 hours therefore arriving at destination at around 9ish BUT according to the RNS510 I would not get there until 2am ??????. It seemed to think I was travelling at 50kph. When we got closer to Brisbane it corrected itself .....buggered if I know but to say will not be throwing out my good old UBDs for a long time

In saying this though the whole navigation was up the **** it did not even know about the NEW part of the Pacific Highway (which is now more than 1 year old) and was as I said before also trying to ask me to go around roundabouts that did not exist it had no idea where it was.
