Quite easy to get confused by Garmin's apparent ad hoc use of the terms: 'Junction View', 'Lane Assist' (sometimes 'Lane Info'), and Junction View with Lane Assist'. My (maybe incorrect) understanding of these terms is this: the first has Junction Views pics only, the second is usually obtained from LA info embedded in most CNs, and the third has JV & LA info in the *.jcv file so that when that file is used with a CN without 'premium content' will show both the junction views and the lane assist multiple arrows. Perhaps Caty or someone can either debunk or confirm this theory?

Yes, for most countries LA is included in the map sold separately. But for India it is available only in the map sold with the India units and with the map update for the India units. Maybe they need to keep at least 2 premium features exclusive for regional units, and India has no 3d!

I'd tried the JCV with the 2012.20 image and it enables only Junction view, not LA as seen here [Only registered and activated users can see links. ] . What is curious is that though actual Lane Assist which shows up in the top left is missing, with current lane guidance enabled in Garmin IOS software, it shows up very infrequently at the bottom as shown in the image (I'd captured the image at such a rare moment). Which is why I think that Lane Assist information is embedded in the map sold separately also, it is somehow just disabled. I wish I had an image sold with the unit, so that I could make a bytewise comparison and check if it's just some sort of flag byte in the file.

sorry but how are maps different for localised units? do you mean if i own a garmin bought abroad i cant load these maps?

Lane Assist or not, Thanks for the map!

The netload links are dead, appreciate if you could reload IMG version of the files in some other server
