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?

When you turn on your nuvi, it is normal that it shows 2 different maps with 2 different dates.
Try simularing the route, by turning off the old map (go to tools ->settings -> map -> info).
If it still doesn't work, please write here the following: what is your splash screen? (go to diagnostic menu by pressing the battery icon for 5 sec, press next once, press start test and then more) - look at the number next to Splash. It should be D1340-50.
Next, where did you put the maps? Old map is probably a gmapprom.img in the .System folder. Disable it by renaming it to e.g gmapprom._img and move the new map into the same location, giving it a name gmapprom.img (if you have unl files together with maps, make sure you move them as well).
I assume, you put the correct JCV file into the JCV folder within .System folder. You can also repeat the procedure by putting JCV into Garmin/JCV/JCV file, but keep the old map disabled.
Personally, I keep my map on a SD card, in the Map folder, and JCV is in Garmin folder, also on SD card. Probably if you have map in "Map" folder on your unit, JCV should be in "Garmin/JCV" directory.

I thinks it is highy unprobable, if the splash version is correct that FW version and gupdate.gcd file would affect the outcome.

Very odd. I wonder if some models have different hardware/GPS chipsets (MTK)?
The current download for my nuvi 1250 is only up to v4.80.
Checked again today.
Note difference to the common 5.10 here:
"nuvi 12xx ([GCD File) software version 5.10" dated February 28, 2011
and mine (AUS/NZ model):
"nuvi 12xx (GCD File - MTK) software version 4.80" dated March 7, 2011

Oh well too bad for me.:angry:

And what about "Routes"; 14xx support this function.

dvazg · 21st March 2011, 10:22 AM

So far Routes are not available in 13xx series.

@scubadoo: this firmware flashing procedure does not apply to MTK models - sorry. Maybe in future we might do that as well. Can you please write here your splash version? (how-to: see post 106)

Attached OCR capture from my nuvi 1250 MTK version:

dvazg · 21st March 2011, 11:59 AM

can anybody show here splash screen of a nüvi 1390, 1450 or 1490 MTK version?

**ddabcd277** · 21st March 2011, 01:48 PM

@ scubadoo

The trick should work also on the MTK model but it should be used MTK boot.bin to flash the Splash. I think the guys can help you prepare such .rgn.

So far Routes are not available in 13xx series.

They are available but locked. Not possible to be unlocked via Splash. Need firmware patch.
