Topo AUS & NZ v4 (August 2012): gmapsupp.img size = 2,979,264 KB and contour lines each 10 m.
Topo AUS & NZ v5 Lite (August 2014): gmapsupp.img size = 1,430,176 KB and contour lines each 40 m.
I think "Lite" here means more than just "no ActiveRouting", less contour lines or a compression rate more than twice as high...

Topo V4 is actually 20m contours. Originally Posted by smokefree

Looking at this Lite version, it's actually a major rework from the previous versions 2, 3 & 4. Visually different data and styles, some additional details particularly in metro area's including some paths, and more POI's including in some rural area's I checked.
Unlike V4 it's definitely not routable, despite the comment referring to "turn by turn". Selecting address search gives "No map data".
I tried enhancing by overlaying the OzTopo 10m contours similar to what I do with CN, on my phones Street Pilot the styles are radically different which highlights the contour line mismatch and looks a lot weird. On a 3597 it won't even allow selecting both, selecting the second automatically deselects the other.
Certainly looks like a Pro version is on the way.

If that is correct, Garmin provides incorrect information about V4 on their website: Originally Posted by Bushwalker8

Yes the website is definitely wrong, all previous release Topo Aust version 2 and Topo Aust & NZ versions 3 & 4 are 20m contour intervals. Originally Posted by smokefree

Personally I prefer the 20m as good balance with less clutter for hilly area's. None of them are accurate, it's purely a visual thing.Last edited by Bushwalker8; 27th September 2014 at 03:55 PM.

G'day, I got Topo v5 up on my Nuvi 2797. Looks good with 3D shading!
But I noticed when I select Topo v5, CN SENSIS & HERE are automatically deSellected!!! (Even OSM)
NOT happy!!!!!!!!! I was hopping to use the other maps to provide auto-routing. (Like I do with ozTOPO V3)
5m Contours & BlueChart Contours are OK.
Although TOPO v5 has contour lines at 20m intervals, I believe the web site refers to 40m DEM.
