Thread: Garmin City Navigator India NT 2012.30

I've found that routes depend on the software as well as the map. Mobile PC, Mobile XT and Garmin on IOS give me different routes with the same map image in some cases, with the XT one providing the best routes, followed by Mobile PC and then Garmin IOS. On Mobile PC, I've actually seen progressively better routing with each map iteration.

In the present 2012.30, an improvement is that on highways, even without LA, it does say to keep right for the flyovers, whereas with the previous image it just showed the distance till the exit from the highway, which would leave drivers unfamiliar with the highway confused as to whether to take a flyover or not.

But I think that 2012.40 might be released quite soon as they've made a mess of naming various portions of the highway and other roads. For example a large portion of the Western Express highway in Mumbai is now called Ali Yawar Jung Marg (which the Garmin lady amusingly pronounces Marginal), while it is actually just a junction near Bandra. And this is not just an isolated case. I think that in redefining the junctions, so as to provide guidance for flyovers, they've unwittingly renamed entire portions of the highways and other roads after junction names.

Edit: Search is much faster with 2012.30

Got hold of a map and jcv file meant for an India unit. Here's the JCV file for the map [Only registered and activated users can see links. ] Please do not use it in a Nuvi that does not support Junction View, as it might cause booting issues

I had a very strange experience with this. I put the map and JCV folder into my ipod and as expected I could get both LA and JV as in the pic below



Now for the strange part. I then thought I'd just verify if the LA was from the map or whether from the jcv file as suggested by Neil. So I used the old image posted in this thread with the JCV file and again got both LA and JV. Then I used just the new map file without the JCV folder. Got LA without JV. Now the even stranger part. Then I used the old file without JCV. Again got LA without JV! I rechecked, deleted the files instead of just renaming them and it still was the same. I also made sure I was killing the Garmin IOS program before re-checking. So now, I'm getting LA using the file which did not have LA enabled before! Inexplicable!

So, someone with a Nuvi (preferably a large screen one as the JCV was meant for a unit with 800 x 480 resolution), please check and report if you get both LA and JV or just JV. Please check the simulation on a prominent multi lane road in a major city like Mumbai or Delhi. I made a cursory check of the 2 map files, both are exactly the same size and have very few differences. If the LA is from the device map file, I'll try to make a patch file for the image posted in this thread.

Request a mod to please post the jcv link in the first post. On a side note, I really love this forum (may not be obvious with only a few posts to my name) and I love reading up the posts by the various experts here. And in no other forum have I seen an admin as warm, helpful and patient as Catymag!

We don't see this enough in my opinion. Caty deserves far more 'bouquets' like the above and I know that it and this reply are technically OT but for once I don't feel even slightly guilty about that. Good on you manojmat, i've actually 'snotted' a few users for disrespecting Caty, not that she needs me or anyone else to defend her honour, her reputation speaks for itself (and so can she). Great to see appreciation and respect so clearly expressed and i'm sure 99.9999999% of users think like us too.

So what is your best guess on what occurred there? Do you think that maybe the running of the JCV somehow 'enabled' the LA info in the map, rather than the LA info being included in the jcv file (which it mustn't be of course or LA would have disappeared when you removed the jcv file). This has got me interested enough to dl the map and jvc to try in a nuvi, first the map only, then map & jcv, then map again w/o jvc to attempt to duplicate your ipod findings. I'll report asap.

Oh, Catymag's a 'she'? I'd not known that!

I'm really at a loss about the LA part. It could be that
1) I'd made a mistake when I first checked for LA and it was actually there all along
2) As you said, the LA info is in the map file and got enabled when the jcv was used. But the question is, where is this info about LA enablement stored? The map file still shows the earlier modification date. Is it somewhere in the program?
3) Maybe the key was using the Indian device map file. Because as I mentioned earlier the 2012.20 jcv did not enable LA. I do not have an Indian device 2012.20 img to confirm this theory.

Edit: Going by Neil's post below, maybe possibility 1 is the answer

LA and Speed Limit are "embeded" in the Map.
You do not need the JCV file for the above to work.
Junction Views come from the corresponding JCV File for the Specific MAP.
That's how I think it works on a Nuvi, Could be Wrong !

That's exactly how it works on a Nuvi (and you're rarely wrong about anything dasilvarsa .) The map is running in my US/AU 1450 presently and on that simulated route from Mumbai to Bandra/Kurla Complex and back it is showing LA on many turns, with no JCV file loaded. But that's not how it worked for manojmat on his ipod is it, but why? .....

.......... I've now loaded the jcv and getting full screen Junction Views as it should be, as well as the LA display. It seems there is no SLI on this map though. The LA screenshots below are a mixture of before and after the addition of the jcv file:

No big trouble really, but thanks for the acknowledgment. I'm not sure how helpful my results are because i'm not using an India localised unit. It would be interesting also to see what results a local nuvi gives considering the previous ruminations on what the local fw may and may not do with these maps.

Speed Limit Indicator. Should show where the "+" is in the red circle on your ipod. On my us fw nuvi it shows in the same place but usually in a rectangle. It's obviously not present in this map.
