"Best' is a subjective and personal preference.

I personally like the large D3060030A.jcv on my 855.

I tried to use this file D3060030A.jcv (770.511 kb) in my nuvi 765T and it doesn't work. A white blank screen appears and no junction view is shown.

What i'm doing wrong

Hi, I have a 1490T with 2012.20 unlocked image and the D3060030A.jcv file (the big one) installed on a 4 GB SD card. The junction view display works just fine, it uses the entire screen, it's clear and not squished in any way. I am quite happy as I have quite a few junction views for our city of Saskatoon.

I would re-download it and attempt again. Corrupt file maybe as most are uncompressed/not archived as a download. (ie raw .jcv file, not as a .rar or .zip)

Also, where are you placing it? SD card or on the unit itself? Whether SD or unit the JCV should be in \Garmin\JCV

Too, check that you don't inadvertently have two JCV belonging to the same mapset. I don't think that works and might explain the blank screen. Not 100% sure though.
