CN EU 2015.40

That's not much space. You could move the JCV folder which contains the junction view files from your nuvi to the card. That would then give you enough free space on the nuvi.

It'll automatically read them off the card. On your model they need to be a folder named Garmin\JCV

Correct. It's different on the card.

Well it may have seemed like that but that is not how the update process works. Each 'map update' is a completely fresh install. What should happen (but for various reasons may not) is that the program (either MapUpdater or Express) will delete the original map that's loaded. MapInstall may do that too depending what options you've chosen, but even so the new map is a fresh install.

What may have confused you is that the update process downloads the files which are used to compile the .img map (the one that is eventually sent to your nuvi) so having downloaded them for the update of your 2598 they were already resident on your PC, which is why the update of your 760 appeared VERY quick.

The basemap is simply not updated, and never has been. Occasionally you may find newer nuvis have a different version, but older ones are never updated. The basemap is only there to assist you should you go outside of the area covered by your detailed maps, and is quite a poor map, with only major roads and towns. You can see what it looks like if you deselect CN EU on your nuvi. What you then see will be the basemap.

No - I am not confused - I have had Garmins for many years and regularly updated so I am aware that, this time whay happened was diffreent and, more to the point INCONSIsTENT between the 2598 and the 760.
I am very aware that the dowload process places a large nunber of img files on the PC - either temporarily if Device only is specified, or permanently if you ask for PC as well or instead.
With the 2598 I left the SD card in situ as I have done with all the updates to this device - at least 3 prevous NTU updates. Instead of deleting the 2015.30 and installing 2015.40 it put the new map on the SD card and left the old one on the device -Seems a bit odd (or maybe not to you?).
I had the img files on the PC so removed the SD card and tried using MapInstall to do what I wanted. It refused as there were only a few hundred Mb left on the device. I had updated BaseMap so tried that (which uses MapInstall) - same problem. It is ABSURD for a user to have to go int MSM to show .System to manually delete maps so I restarted Express and, with the SD card removed did a new install. It appeared to ignore the img files already downloaded and took just as long to download as it did on my first attempt (I'm talking about just download and ignoring the map indexing and transferring in both cases - download is about 3 hours on my 2Mb connection).

Today, with the 760, I quiockly discovered that I needed an NT mapset not an NTU. Express downloaded that in about 15 minutes, much like previous experience of updating the 760 after the 2598 (and I do know that NT maps are ony updated twice a year). Obviously it then spent an hour producing the integrated map and transferring it. In that process it DID, CONTRARY TO YOUR ASSERTION, delete the old map, which is of course not in a hidden folder, so it may be that the latest version of MapInstall cannot delete files in .System but can delete files in Garmin

So, YES, I do understand the basic processes involved and in my case they appear to have changed and to be INCONSISTENT between NTU and NT or between 2598 and 760.

Maybe I was unlucky and there was a glitch somewhere - hence my original post asking if anyone else has noticed the different behaviour.

I have sent an email support request to Garmin asking that they look at the issue and, potentially, patch MapInstall to delete the old map for new devices just as it plainly does for old devices.

And, as a kick in the tail, when I connected my 760 to the PC after it had acquired its satellites it threw up a message that CNEurope NT2015.40 is more than a year out of date - EH????? At least it only did that once!

Well like you I've used Garmin's for years and am a mod on the Garmin forums. I'll resist the urge to argue your points, if you believe you're correct then that's fine by me.

However just note I didn't say Express doesn't delete maps, I said it should but for various reasons might not Wink

If it can it will delete them regardless of whether they are in .system, Garmin or Map, either on the nuvi itself or the sd card.

The problem generally comes when folks have either manually renamed or moved their map files, so Express then won't delete them since it can't tell whether that move/renaming was intentional or not. I think you'd agree we wouldn't want Express simply deleting any map it could find.

Don't let us get into bitching at each other. If I have used capitals in places that is merely to emphasise particular aspects of my experience.

I think it should be reasonably clear from my earlier comments in this thread that I do not meddle with map files. I was tempted to solve my problem of the non deletion of the 2015.30 map by going into MSM mode and manually deleting but, as I said, I did not do that and tried a reinstall after removing the SD card and that worked, albeit with the time penalty of APPARENTLY downloading the image files from the Garmin server a second time.

You did not mention that Express does not delete maps - you related that comment to MapInstall (which BaseCamp implicitly uses) and it was to MapInstall that I referred. And it is MapInstall that has given me inconsistent results.

So - No - I have not meddled with map files, No - I have not moved any map files and I agree that no application should mess with files whose provenance it cannot trace - hence I might expect the problem that I experienced if I was trying to install a different subset of the full map.

Feel absolutely free to disbelieve my account as you appear to do - I have given a clear account of what happened and in what circumstances and was merely asking whether it was the experience of anyone else. Clearly it did not happen to you and I can accept that. If it has happened to nobody else then I can only deduce that when I left the device alone for a few hours, at some stage it offered an option which I was not available to elect and therefore used a default. But that still does not explain why MapInstall is happy to overwrite a map file on the 760 but not on the 2598.

I remain mystified and will follow up with Garmin Support.
I will post any helpful response.

@sussamb
I have just reviewed previous posts and noticed that you refer to "Map Updater". Is that a current program? I remember Lifetime Map Updater but I thought it had been superceded by Express. I assumed that, because Express is regularly updated (rather like Garmin communicator used to be - if you go back that far) the old versions would not work any more.
Best regards
Ron

MapUpdater came earlier. Garmin then introduced Lifetime Map Updater which never really worked well. It has now been superseded by Express, which was meant to replace both MapUpdater/Lifetime Map Updater and WebUpdater (which updated software).

Both MapUpdater and WebUpdater are still around though and many still prefer to use them. Having said that I've used Express since it came out and with one exception haven't had any issues with it.

Is there a fundamental difference between the maps in the higher Nuvis and the low end models?
Reason I ask is that I have a Nuvi 55 LMT-D and, although Express tells me I have map updates, it continually fails after about 20 mins which is incredibly frustrating.
I have tried installing and using Maploader but it tells me I don't have a "previous version" to install over.
In addition Express wil not update from 4.05.

I'd forgotten how incredibly bad Garmin's infrastructure was.
Compare with Smartphone sat av apps & it's night and day as regards updating.
