Guys, I have a Garmin 40 gps with an older map version and downloaded the 2014.30 Mapsource version of City Navigator Europe and also the D30841520A.JCV file with the "junction view". I used Mapsource to select a few countries and send it to the gps, then I noticed that it has created a new Garmin folder inside the root of the gps and installed there the gmapprom.img new file. As I know that this file must be in the .\System folder I moved it to that folder and it worked OK.
Then I noticed that the "Junction View" function doesn't work anymore and afetr a few search I saw that I have to download a new version of this JCV file, compatible with the 2014.30 version map and I downloaded the D30841520A.JCV file, removed older the files I have inside the .\System\JCV folder (an old JCV file D2922000A.JCV and also another file D2922000A.sum) and put the new file inside that folder, but it doesn't work... it has 312.169 KB. Any help? Do I need also a new xxxxxxx.sum file as I removed a file like that?
