Map Update 2018.20 Ready To Download

One question, could you not just delete the folder:

c:/ProgramData/GARMIN/CoreService/Downloads

On my Windows 10 machine the Firmware, Map, and Temp folders are inside the Downloads folder so deleting Downloads would take the other 3 folders with it.

What I'm not sure of is whether there could ever be anything else inside the Downloads folder other than Firmware, Map, and Temp that you may not want to delete. But if that was the case then you shouldn't be deleting the Downloads folder anyway, I guess.

I just updated too, now i guess i'll update again!

& thus the reason why I don't delete the entire folder.

Ah now I see, your deleting the contents of those folders. I wrongly read your post when you said cleanup that your were deleting the folder.

How do I get this new update using MapInstall? It only offers 2018.1.

Just use Garmin Express. Works for me everytime and have never had any problems.

thanks for the heads up

Jackrabbit -

I have an old 276C and Express is not compatible with it. I must use MapUpdater.

Just use Garmin Express. Works for me everytime and have never had any problems.

No problem here either.

With each & every map update, when I get to the gmapdem.img file, I always have a thought for you & thankful for the larger version

Updating now.

How can I use Garmin Express? When I go to it I get the message that it is incompatible with my 276C and I must use MapInstall instead.

A couple of years ago I had trouble updating the maps on my old 276C so I called Garmin. The Garmin tech told me I could no longer update maps because the new maps were incompatible with my 276. He switched me to the head tech who told me the same thing. I said, but I have the Lifetime Map. He said the best that they could do for me was give me 10% off their price for a new GPS. But they were not being truthful with me. Thanks to a great guy at the GPSPower forum (which has troubles of its own now) I was able to download the new maps, which turned out to be perfectly compatible with my GPS, and I've been downloading maps ever since with no problem, via MapInstall, all perfectly compatible with the 276C.

Well, hopefully the 2018.2 will show up on MapInstall soon. Someone said that MapInstall might be a few days behind Express. I don't really want to talk to Garmin again.

MapInstall only works if you have used Garmin Express or Garmin MapUpdater to first install the map to your computer. MapInstall by itself will not download the map from Garmin. Since you cannot use Express for the 276C you will need to use MapUpdater. Hopefully Garmin will enable the 2018.20 map for MapUpdater, but is sounds like so far it is a "no go".

For the life of me I cannot remember what it is exactly, but copying to the SD card using Mapinstall or whatever via downloaded maps to the SD card there is something that you will not be able to do using the map on the GPS via SD card. Something is missing that the Garmin install to the SD card gets.

Maybe this is what you were thinking of Melaqueman: MapInstall only installs the map (.img) file. On newer devices that have advanced features, MapInstall does not install things like Junction View (.JCV), voice recognition (.ASR/SRX), 3D or digital elevation images, or the advanced navigation features contained in the .SID files.

However, if you download the map update with Garmin Express or Webupdater to a SD card or if you use cloning, you definitely will get all these files and can manually copy them.

I just looked at this folder and the complete Garmin folder takes about 20.6 GB of space for 3 maps i.e Europe 2017.1, NA 2018.1 and NA 2018.2 including the CORE Service folder. I always leave the previous version of NA.

I don't really see what you have removed, but assuming it is the complete CORE folder I would gain about 10 GB. But to what possible detrimental result?

I knew it, just could not remember the exact files Mapinstall can not do. Thx alanb for the info.

I guess I said MapInstall when I meant to say MapUpdater (and it looks like there's only a brief time that I can edit my posts here). I get confused with all their names. So now is Garmin going to try the same trick on me again that they tried a couple of years ago, not letting me update the maps on the 276C?

Map Updater has been discontinued for quite few years now. It may be disabled at any moment. Officially Garmin is not releasing any update any more.

So far Map Updater was working for you because of troubles with Express. When Express had bugs that make it impossible to some to update maps Garmin was using Updater as backup. But as Express is working fairly well now they may dump Updater for good.

So Express doesn't work with yours 276 at all? Doesn't recognize it and your Lifetime maps? With my 770 I have to install maps to computer only first and than transfer them to GPS by MaInstall. But my device and LifeTime maps are recognized by Express.

grzesja -

How can I install the maps directly on to my computer?

Garmin Express gives me this message:

"Garmin Express does not support this [276C] device. Please use Garmin Map Updater.

Please contact Garmin customer care for help."

I'll call Garmin tomorrow. Most likely they'll try the same gag on me they tried two years ago, namely, "the new map is not compatible with your device, and Garmin Express is not compatible with your device, and the lifetime maps you bought is no longer in effect because the lifetime of your device is over."

Lifetime is Lifetime !!!

I bought the lifetime maps for my now ancient 855 a long time ago and have no problems other than having to use the CLONING method using an 8 GB SD card.

It's certainly possible that GMU will cease to function or stop offering map or software updates. But if Garmin does this, they are also dooming the few folks that still use Windows XP:

In general, Garmin recommends that Garmin Express be used for map and other device updates. But several users continue to use an alternative, GarminMapUpdater, and at times Garmin also has recommended GarminMapUpdater for those users having difficulty updating their maps with Garmin Express. In fact, GarminMapUpdater is now the only means for doing map updates for folks updating with a Windows XP computer:

Well, I've got major problems with the 2018.20 map update on my 1390T. Map update installed with no problems but...it shows no roads. Doesn't matter how far in/out you zoom on the map there are no residential streets shown. It just show the car icon in a field with a couple of roads in the distance about 2-3 kms away but it's wrong and there are no roads like it around here. I reloaded and updated the map 3x and did a hard reset 3x and there is no change. I used Garmin Express, maybe the map download screwed up. Anyone know where the map is stored on the computer running Win 10? I want to try an re-downloading it to see what happens. Right now it keeps rebuilding the same map download. Grrrrrrr.

The map update works fine on my 2495 LMT.

"Lifetime is Lifetime !!!"

Not in Lawyer-speak.

Would it be possible for me to use that cloning method too? If so where could I find directions for doing so.

The 276C was discontinued in 2009 but it still has many devotees because of its unmatched versatility. Garmin introduced a so-called new and improved 276C recently, the 276CX, trading on the rep of the original 276C. It's a disaster.

It's possible that your 1390 has been updated to the newest map. Go to your map page in the nuvi (Map Info or myMaps, I'm not sure which way the 1390 finds the page) and see what maps are listed there. If you see 2018.20, is it checked? If there and unchecked, you will have exactly the problem you report. What you're seeing is the Garmin Basemap which is always present. If unchecked, the new 2018.20 map will not be displayed. Checking it fixes all

Here's hoping this is your issue since it's the easiest and quickest fix possible.

@jackrabit000 ... Did you install the full NA map or a reduced region (like lower 49)? Did you install to a SD card or to the internal memory of the 1390?

Even if Garmin Express didn't give an error, something obviously went wrong. The 1390 has very limited storage (less than 2 GB usable) so your best option is to install the map to SD. Make sure you have a SD card with sufficient free space (4 GB or more) and try a reinstall.

Jackrabbit -

" Map update installed with no problems but...it shows no roads..."

Well you got further than me anyway. Did your MapUpdater show 2018.2? Mine only shows 2018.1.

So many people will be calling Garmin tomorrow there will probably be a three hour hold time. Oh I found one trick that used to work to get through to them quickly, but it would only work with the 276C not with regular city street units. I don't know if it still works though...

Yes rather!

I already looked at that and the 2018.20 is checked.

I never received any error. The full NA map is installed and on the SD card. SD card is 8GB with lots of free space and had the 2018.10 on it and that ran with no problems.

jackrabbit000, the fact the 2018.20 is showing on the Map Info is a good sign. Have you tried a master reset? If that doesn't work, the map file must be corrupted in some way, so I still think a reinstall would be in order.

Mine shows 2018.12. It just doesn't work. If I try to simulate a route to my work place 17 kms away, the map shows me in an open field and sends me to a spot about 2 kms away in the middle of nowhere. I have done the master reset after each map install.

@werewolf ... the problem with the 276C (other than the storage limitations) is that it doesn't support mass storage mode or MTP. If I recall, that is one of the old devices that uses Garmin communication prorocol (or something like that) and that's why Garmin Express isn't compatible with it. It is also why the cloning method isn't an option for you. MapUpdater supports devices with this old communication protocol, so I think your only hope is that Garmin enables 2018.20 on MapUpdater.

If ever you want to do a fresh install, delete the following, reboot your computer & then fire up Garmin Express.

C:ProgramDataGARMINCoreServiceDownloads
C:ProgramDataGARMINCoreServiceDownloadsFirmware
C:ProgramDataGARMINCoreServiceDownloadsMap
C:ProgramDataGARMINCoreServiceDownloadsTemp

Good luck and let us know if you encounter any other problems.

Thanks Canuk. Going to try this and re-download and see what happens.

It's safe to delete the files I mentioned, they are "leftovers" & are useful only if you want to reinstall a mapset or firmware & avoid a new download.

Once I see the maps are working correctly, I know that I won't be downloading them again therefore I delete the mentioned files in order to save several GB of disk space.

Storage limitations isn't a problem for me. I have the 512MB Garmin proprietary memory card + some older ones, 256 and 128. I'll call them tomorrow, but, like I said, I'm afraid I know what they are going to say.

Although the 276C isn't listed in this faq:

http://www.poi-factory.com/node/42561

I wonder if it's able to read files greater than 2GB in size, assuming the failed map update was all of North America which exceeds the filesize limit of many older GPS devices. A test would be to reinstall the map, choosing a North America subset map of less than 2GB in size. If the map was originally installed to the device and computer, no more download is needed, but rather use MapInstall to select a map segment under 2GB, install, then see if the 276C once again has roads, etc. If this works, then depending upon the number of map filenames allowed for the 275C (gmapprom, gmapsupp, gmapsup1, etc.), additional <2GB map segments could be loaded to gain more of North America.

The 276C can't read map files of even 2 GB because it doesn't have that much storage. As I understand it, it also doesn't take standard SD cards, but a proprietary Garmin memory card ... largest available is 512 MB. So Mapinstall is the only option for installing the specific region you want to use at a given time. And as we have already said, you need MapUpdater (not Express) to get the map to the computer in the first place. I am sure this is why the official Garmin stance is to just say that current CN maps can't be installed on the 276C. As werewolf knows, that isn't quite true though if you are willing to accept the limitations. But unless Garmin opens up 2018.20 to MapUpdater, I think there is no way for werewolf to get the map on his computer.

Actually if he had another Garmin device with lifetime maps, he might be able to download the map to the computer for the other device, then manually unlock it for the 276C and use MapInstall to transfer to the device ... an "iffy" process at best.

Guys - What you are saying is something like what Garmin tried to tell me two years ago when I couldn't download one of their updates. Then I went to the GPSPower forum and a very nice feller there - their global moderator -showed me how to do it, and since then I've been downloading all the updates with no problem. Yes I download the whole thing straight to my computer and from there I select the maps I want that will fit on my memory card and move it to my 276. That's the way I've always done it. The problem is that in order to download the new map to my computer I first need to get Garmin's OK byplugging in my GPS. Second problem is due to a huge meltdown and mysterious legal problems at that other GPS forum the feller who showed me how to do it - duh i forgot how - isn't a available nor are the old Posts containing his instructions. One good thing is the feller above said he downloaded the 2018.2 via the MapUpdater, even though it didn't work, so maybe they are slowly making it available.

Who are you referring to that installed 2018.20 with MapUpdater? I have not heard of anyone yet where 2018.20 was offered through MapUpdater.

Here we go again ladies and gents...

Well Canuk, I've taken the plunge and deleted the files you suggest. MapSource and BaseCamp are working fine using the installed maps, sans the deleted files.

I guess if there would have been a problem just reinstalling from Garmin would have fixed it.

POIfactory will not let you put in a back slash but it will let you put in a / forward slash

I guess that's what canuk ran into as well.

For some reason I thought Jackrabbit said he downloaded it via MapUpdater. I was wrong. It was G Express.

I just notice a used - maybe 13 years old - it was introduced in early 2004 -going for $540 on EBay!

Not right. I've used MapInstall exclusively for my 1450 and I can assure you that it installs more than just the map. For instance, after every install I need to reinstall the large JCV file because the old one was replace by the new, small JCV file.

Phil

Just updated the unit, seem to be no problems. Will try it out this week and see if there any changes.

Yup, you must be right. You can't create a \ here.

http://www.poi-factory.com/node/46831

I'd have to agree with alandb on this one. I think you maybe using MapUpdater to update your 1450 and not MapInstall. AFAIK MapUpdater will install all the update files like JCV, etc. but MapInstall is only used to install all or parts of a map on to your device.

I stand corrected. I didn't notice the different name.

Phil

Glad to get fresh maps just before summer.
