Interesting Junction view

That view pops up occassionally on my 2597 on one particular interersection in Ottawa, ON. Also noticed it a few times on a recent trip to PEI.

Thanks for the link, that 3d view looks confusing, I like the birds eye of an interchange though

I don't get bird's eye junction view on my 3597 and nuvicam.

There aren't a lot of them and you have to be driving in a location where there is one in the map data. Obviously there is one near Philly as shown in the posts above. I run into one in downtown Seattle using my 3597 all the time. Possible there isn't any Bird's Eye views in the MTA.

I have seen a few of the birds eye junction views on my 3597. In some ways I think they are more useful than the regular JCV's as they give an overview of the whole interchange.

It is my understanding that both the birds eye jv's and the active lane guidance views are part of the map data, while the photo real views come in the .JCV file as we know. Assuming that is true, it is probably one of the reasons for the size bloat of the map .img file in the last few map updates.

Thanks for your feed back. So far I have not seen any in Toronto Canada area. May be there is non in Toronto.

Ditto, a more realistic idea of what to expect is always the best.

I have a question. If you have a junction view capable Garmin, is this "birds eye" junction view part of a map update? I haven't done one in a while as so much major road construction has been going on in central Florida, but I've been getting ready to bite the bullet as a lot of the major stuff I deal with is finishing up.

What model nuvi do you have and use right now? Birdseye and active lane guidance can be seen on the newer models.

Not many bird's eye views in Central Illinois. Makes me want to drive to the bigger cities!

Guidance 3.0 is Garmin's most innovative navigation engine and includes all of the features of Guidance 2.0 plus more. Guidance 3.0 adds myTrends™, the ability for the nüvi to automatically remember frequent favorite route destinations and predict the destination without the user needing to activate a route. Also included on select models is Safe Texting, a text reader feature that allows the driver to receive and hear texts without taking their eyes off the road. And photoReal junction view is enhanced with Guidance 3.0 with Bird's Eye junction view, which highlights the proper lanes on complex junctions with overhead perspective.

Differences between Guidance 2.0 and Guidance 3.0
Some Garmin devices may indicate a specific Guidance version on their packaging. Guidance 2.0 and 3.0 refer to features present on automotive devices. To view the features of each Guidance version, see the lists below:

2The nuvi 3450 and 3550 do not come with lifetime traffic.

I prefer the birds eye view on junction better as well.

I always thought that a split-view of the exit with the signage on the right side (photo real view) with the corresponding bird's eye view of the entire interchange on the left half for the last 1/4 mile would be close to ideal. My 2595 does zoom in to show the pseudo bird's eye "map" view of the junction in 3D mode but depending on the complexity of the interchange it's lacking at times.

I'm in the Philadelphia, PA area, a pretty big metropolitan area, and the one "birds eye view" I created this thread about is the only one I've ever seen.

How does one know if their GPS is using "Guidance 3.0" or "Guidance 2.0?"

Is there something you can look at inside the GPS proper and it will cough it out like a fur ball?

TIA

never saw that. was this two different junctions or the same one.

Two different views of the same interchange. As I was approaching the interchange the birdseye view displayed up first, then as I got closer the normal view came up.

I believe this is always the case when starting with a Birdseye view. Once you're about to have to change lanes, the normal JV appears.

I'm not sure about Active Lane Guidance switching to another JV since I think I've only seen one example of Active Lane Guidance with my nuvi.

Just curious, how was it determined that Birdeye and Active Guidance data are in the map file rather than the jcv file?

To me, it would seem more logical to have these two JVs as part of the JCV file. If built into the map, it'd mean that all the older nuvis with no JV offered or with full screen JV displays would have the birdseye and Active Guidance data in the map file, making the map file larger for these folks with no benefit to them since the older machines can't show either of these JVs. If the birdseye and Active Guidance were in the split screen JCV file not received by the older devices, the map file would be smaller and the map updates would be able to be stored internally in these older devices for a longer time since the file size is smaller and the birdseye and Active Guidance data would be installed mostly to the newer devices with the split screen JCV file that are able to use the data.

Hmm, maybe birdseye and Active Guidance were added to the map file in order to make the older devices less able to hold the entire map internally in order to have these owners more quickly feel the need to upgrade to a newer device. Could Garmin be that Machiavellian? If so, Niccolò would be proud.

After the 2012.10 map update release, some devices will now display Junction View in a split-screen mode. https://support.garmin.com/support/searchSupport/case.faces?...

I recall (I think) reading about this in a forum ... don't remember if it was POI Factory or a different forum, and I can't seem to find it now. But the poster was saying he or she didn't have the .JCV file (either deleted it or had wrong version), but still had junction views. It turned out it was either birdseye or active lane guidance they were seeing. Unfortunately, I don't remember the exact details, but maybe some other member remembers that discussion and can provide a link.

Ah, interesting. I should be able to test the birdseye part of the question (but not Active Guidance) by disabling my JCV file, then driving a route near me that has a birdseye view. If you're remembering correctly and if the person reporting that knowledge is also correct, I should still see the birdseye view but not the regular JV. I'll report back.

[Later] After disabling the jcv file in my nuvi 3597, then doing a full powerdown/reboot, I simulated a route that I know contains a birdseye view JV followed by a regular JV. I found that with the jcv file disabled, both the birdseye view and regular JV did not appear. To me, this strongly indicates that the birdseye view data is built into the jcv file and not the map file.

My assumption is that alandb is correctly remembering something he read (my motto: always assume alandb is right), but my guess is that the person who posted that s/he still received birdseye views without a jcv file was probably wrong. It could be that this person had a jcv file but since it was in a subfolder of the .system folder, it may not have been findable if the person hadn't properly reconfigured the Windows folder options.

Just a guess. But to me, I do think that birdseye data (and quite likely, Active Lane Guidance data) are built into the jcv file with each map update that comes out and that removes my earlier thought of Garmin acting Machiavellian with respect to where data is stored.

I would agree with your conclusion Craig. My memory does not always serve me well any more.

I just repeated your test in simulation mode Craig. I created a route from Miami FL to Disney World in Orlando. I am pretty sure this route has all 3 views: regular JV's, birds eye JV's, and active lane guidance. I renamed my .JCV file (on my 3597) and simulated the route. As you said, I saw no junction views or birds eye views. but I did see many split screen active lane guidance views in the early part of the trip leaving Miami on I95.

So it would seem Acive Lane Guidance is not contained in the JCV file while birds eye JV apparently is. This kind of makes sense because birdseye view is a static view where active lane guidance keeps track of where you are and changes the view accordingly.

I still can't find the forum thread where this was discussed, but it seems possible that I at least didn't "dream this up".

It's more like a nightmare, not anything you might have dreamed up!

Well done. I rescind my earlier guess. For future reference, I've updated the FAQ:
