Enhanced JV as seen on the nuvi 3790T in 06/2010 by BAVC10
Updated by GpsPasSion 20100616 : The first user reports from the UK on the nuvi 3790T are quite enthusiastic as expected (slick, fast, nicer maps, better routes, etc...) but an unexpected and unannounced development are the new "Junction View" screens . Not only are they apparently more numerous but they're also "photo-enhanced".
Orignal Message : I am just wondering what I am missing. Yesterday I drove from Ontario CA to Salt Lake City UT and did not see the "Junction View" feature on my nuvi one time. As we came through Las Vegas we took a detour to get gas. After filling up we made our way back to the I-15 by way of some other freeways, several of them being somewhat confusing. In my thinking that would have been a good place for it to pop up. Nothing. Am I missing something? Do I need to register before it works? I do not see a selection to turn this feature on/off. The traffic feature did work and I saw several ad's, but no big deal.
Thanks for your thoughts,

Off topic and not true, HTC EVO 4G for instance and the T-Mobile 1000 minutes / $100 is not bad too ;-)
There must be some "reason" for the lack of JV, either Navteq don't want to invest in them or they have them and Garmin don't want to pay for the "full" version.

The US market is last to get everything. Look at cell phones for example.

Yes, completely off-topic, both interfaces are excellent in their own right, it's mostly a matter of getting use to them, discussion of their respective merits should go in the 1490/XXL 540 comparison topic.
It's a bit hard to understand why JV signs are so far in between in the US, especially since highway intersections can be quite tricky, much more than in Europe on average, but I don't doubt that Navteq is working hard to update them.

Completely off topic but, the 3790 seems very cumbersome and not so user friendly compared to the TomTom? What makes the TomTom's countless pages of nested preference settings "user friendly" and not cumbersome?
Have to admit that TT does have more Junction Views however.

As a new owner of a 3790t (formerly from the TomTom camp) I too was disappointed when finding a lack of JV screens when navigating. Simulated routes in California popped some up, but absolutely nothing, nada, in my home state of Connecticut.
Oh, lane assist is there, at times showing as many as five lanes and the proper one to be in, but NEVER ever showing JV for any of those Connecticut junctions. WTF?!? This was one of the points that sold me on Garmin vs TomTom, now come to find out that JV is implemented in only a few select US states?!?
Garmin support informs me the JV screens flash up and off very briefly... I know, I've seen the California JV screens during simulations thank you, but I have never seen a JV screen for my neck of the woods (Sigh!) I feel snoockered, having bought something that does not do what it purports to (grrr!)
Ahhh... sorry for the rant, but it was very cathartic (feeling better now!)
FWIW: maybe it's just a learning curve or lofty expectations and I'll eventually warm up to the 3790t, but for now it seems very cumbersome and not so user-friendly compared to the TomToms and even the ancient TeleType units I've owned.

Be sure you've found correct road/point because my mentioned coordinates has other format than nuvi default.
- change your default setting in nuvi before tests or
- find highway A8 before Munchen Sud
I believe it must be problem with your JV test. Don't give up.

I tryed all methods of simulations you pointed to me but without success on 3790t:-( Sorry maybe i'm stupid
||Posted - 03 juil. 2010 : 00:10:20
Turn off the GPS and set the position on the map, looks there is some catching up you need to do to make good use of your GPS, a good place to start : * READ ME FIRST - INDEX/FAQ/POLICIES * 05/2010 ;-)

i can't to simulate the route between these 2 points, trying but it always is starting from my current position
||Posted - 02 juil. 2010 : 23:19:59
Use simulation from (N48.00811 E11.66937) -> to (N48.02740 E11.63935) to see JV in Europe (Munich, Germany).
more sample and coordinates for testing on Polish forum

i wrote only because i would like also to see such pictures as above on my nuvi, and arrows in left upper corner of couse

Not true, we have many reports of JV working fine on European units, actually the screen captures added in the first message are from a UK model and there are reports of JV working fine on French units too, but not with the new "photo enhancement".

yes, i have 2504000a.jcv. But, the time of my trip i hadn't possibility to upgrade ROM of my nuvi and i did it only 2 days ago to v2.20. Map is CNE 2011.10 april. And of course i did routing everywhere because it were absolutely new places for me. As i read somewhere on Russians forums JV and LA are not working on European versions of 3790t yet and are in test mode yet.

@slachizh, a couple of things. Did you have a route entered in your 3790, for example did you ask the Nuvi to take you to a specific spot like a hotel in Paris. The reason I ask is that if you hadn't asked the Nuvi to calculate a route for you but were simply driving with the Map Screen present, then the Junction View screen available on the 3790 would not have been presented to you. You need to be driving a calculated route for any JV screens to appear. You also need to have a route calculated to see any "Lane Assist" items which will appear as multiple arrows in the upper left corner of the Map Screen, where the Next Turn arrow is presented.
If you did have a route calculated then your Nuvi should have show a JV screen or Lane Assist arrows for each intersection you past where this data was stored in the JV or Map files. It is possible that you never drove through an area that had this information available, however unlikely that may seem. Jinction View and Lane Assist can't be turned on or off on 3790T so if you had a route planned and past a spot where the JV and Lane Assist data was present, you should have seen this on the map screen.
Although you should check the map version as gpspassion suggests, on the 3790T the menu options have changed and are now Tools - Settings - myMaps. You will not find the Junction View file there however. To check for the JV file you need to attach the Nuvi to your computer and check in the JCV folder. This folder is found in the .system folder of the 3790T and may not be visible by default in Windows. If you can't find the .system folder do the following in Windows:
- click on the Start Menu icon in Windows (lower left corner)
- in the Search field at the bottom of the Start Menu type - folder options
- from the search results that appear, select - folder options
- on the Folders Options screen, click on the View tab
- under Advanced Settings select "show hidden files, folders and drives" under the Hidden Files and Folders section
- under Advanced Settings delete the tick mark beside "Hide Protecting Operating System Files(Recommended)" and answer Yes you want to do that when the warning box appears.
- click Apply and then OK to save your changes and close the View Options box
Now attach your Nuvi to the PC and find the Nuvi's internal storage drive in My Computer or Windows Explorer. Open that drive to see the contents and you should find the .system file at or near the top of the listing. The JCV folder should be present inside the .system folder and contain a file with a name like D2339010A.JCV. You'll probably see a file with a different name as this is the JV file name for North American maps while you have the Europe version.
