Then in simulation, press upper left corner and list forthcoming junctions, once you reach a junction with existing JCV image, the (bottom) button will appear.

Hi dvazg,

I am sure that the map and JCV file are matched because i downloaded them recently from this link

[Only registered and activated users can see links. ]

I tried to simulate a very long route (900km) but still there is not junction view available .
Next, i looked into the map. There are two maps on my units. Once came preinstalled, and one I just downloaded from here (unlocked image file) and i copied it to Garmin Nuvi\Map (i don't have the SD card on my unit yet). Once I turn on the unit, i can see 2 maps available (under Map option) and i only selected the latest one that came with the JCV file. And still, the damn junction view doesn't show up :-). One thing i noticed was during start up, My unit showed 2 dates regarding the maps. Something like: 2009 whereis map....copyright....
2010 whereis map....copyright....
Is this normal, dvazg? and regarding the GUPDATE file, doesn't it have to be the one when you last update the firmware? I asked because after unsuccessful at the first try (at flashing the unit), i reinstalled the firmware using the webupdater which give me another GUPDATE file. After successfully flashing the unit at the 2nd. try, i didn't have the latest GUPDATE file at hand (because i bak it up at home) so i used the first GUPDATE file which i saved in the usb stick. Could it be the reason that the junction view doesn't not show up?
