Problem installing 2012.30 Maps

Last night I downloaded the latest map update using the new lmu utility which checks for updates and downloads them automatically.
I have attempted t install them today but during the installation I received an error message
Source file not found: C:\ProgramData\GARMIN\LmuMaps\EU.2012.30\IMG\City Navigator Europe NT\2012.30.gmap\CNEuroNT_2012_30_mdr\CNEURONT.MDR.

Sure enough the file is not there in the downloaded data.

I found the file in 2012.20 maps and there it is over 700Mb so clearly a large amount of data.

I will put a support request to Garmin

Has anybody else found this error?

There have been various problems reported when updating maps using Garmin's LMU program. I'd log on to your myGarmin and download the map the 'old way' Smile

Hi M8s

I've installed the 2012.30 with the "traditional" method by downloading the GarminMapUpdater_v2.7.12.exe and running it. Download and preparation step run as expected but during the 3rd step while installing the maps to the device, about 3rd through the process (23 min remaining), I got an error message that an unexpected error occurred and the program will be closed, If the problem re-occurs, I should contact Garmin support.

Did anybody else encounter that and knows a solution.

I've restored my nüvi 765T from a backup I had and tried again, to no avail.

That is an interesting theory, but I have some doubts.

With the 2012.20 maps, complete of Europe, I've got 339MB free space. Between map 2012.10 and 2012.20 the size difference was about 42MB.
And now the update of 2012.30 shall use more than 339MB more space than the previous one? That would be a BIG update!

BTW: I don't have any other stuff on my nüvi, no mp3 or the like. The only other folder on the device with some notable content other than the folder Garmin itself is Audible with 17MB. I could remove that stuff without missing it, if that would help.

And, I've seen the update procedure complain about missing free space before even starting the update, so I kind of have my doubts that it would start and the fail in the middle of the update process because of a space issue.

Anyway, for the time being, I've reverted to 2012.20 and will see what Garmin answers to my mail. I've sent the error message I got to our local Garmin reseller (garmin.ch).

Good Night!

That smells as though you experienced the same missing file as me - but the traditional method did not tell you.
As some folk have managed to update I wonder if Garmin changed the update file for some reason and substituted a duff download?

Hi Red Squirrel

So, I've taken a test drive and can confirm that for the maps installed on the SD card, the lane assist is not available as opposed to the internally installed maps, where they are.

So installing the maps onto a SD card isn't really the solution.
I'm still waiting for a reply from Garmin.

I had no problems doing the update to my unit, but then again I downloaded them to the computer first, then did a computer to unit upgrade which went flawlessly. Very Happy

Shame it's still missing the major A3 update called the Hindhead Tunnels. Rolling Eyes

I used the Garmin Lifetime Updater to download the maps to the PC first, then once I'd charged up my Garmin, connected it to the PC & it was updated.

It's a slower process, but it works. I gave up on the other one.

Thanks for the information, I'm just running it again that way. It looks like it's copying something but it will take time, I guess :-)

It's me again Very Happy

The Lifetime Updater failed with the same message.

This time I investigated the problem and found the roots, I guess. From a file compare with the 2012.20 vs 2012.30 it shows that all files were updated as expected, except the JCV. The old one was deleted but no new one copied to the device.
I then investigated the files in the Temp directory on the system, where all the downloads are stored, and found the current one, D2504060A.JCV, with a size of 584'362'377, compared to the previous one D3084020A.JCV with a size of 278'281'247. That is an increase of roughly 300MB! You might remember that I wrote that my free space was 339MB with the 2012.20 on the device. As not only the JCV increased in size, also the map itself did, this was not enough.
GMAP3D.IMG was 408'829'952 and is now 448'749'568 (+40MB)
gmapprom.img was 2'403'532'800 and is now 2'494'103'552 (+90MB)

This means, the map size of 2012.30 is around 130MB larger, plus the Lane Assist data which increased by around 300MB, gives a total of 430MB additional space required.

That is 100MB more than my device had left. Sad the update program does not detect that before running into an error without any meaningful message.

Anyway, I could get out of it by removing many unused voices. Before that directory (\Garmin\Voice) used 400MB, after removing anything other than German (I live in Switzerland ;-)) and English, it's 130MB (-270MB). This means, I should have enough space left for the 2012.30 map update. It's currently running again, fingers crossed!

That means, the current map should have a lot more Lane Assist images available. I'll check that out as soon as I'm on the road again!

If that's still not enough free space you can also delete unwanted EULA, text, keyboard and vehicle files Smile
