D3153030A JCV is the only file that supports landscape. The others will have their images stretched to fill the screen on GPS receivers that only support full-screen Junction View. It's readable, and the arrows are clear, but the images are fuzzy due to the distortion.
many thanks for sharing
I experience a funny (...) thing when it comes to POI's on this map. I can see them on my devices (nüvi 200, 350, 775T) when browsing the map, but can't search for them. A search in whatever category returns an annoying "No Matches Found". So no restaurants, no petrol stations, no public transport terminals, etc. Yet I can see them when browsing the map! Is there any explanation (or fix!) for this? Does anyone else experience this on their Garmin device? I don't have this problem with CN Europe.
Just tested CNNANT2012.20 on a nuvi 200 with a few quick searches, and the POI search function seems to be working OK for me.
Just a word of warning about this JCV file: it's huge. 752MB, but unlike the other JCV files, the images aren't distorted. It also works on 1xxx units, despite Garmin's claims.
I highly doubt there are more junction views in this file than the D3191020A.
Why so big for older units?
If I use on my 765T, it will have to go on an SD card.
