City Navigator North America NT 2011.30

**MikieP** · 29th November 2010, 02:27 AM

Reverted back to 2011.20 and all works again. The single variable I did not try was to remove the renamed D2339030A.JCV to D1279080A.JCV on the 885T during the complete install of 2011.30, ASR and JCV files that failed to Find Address by voice command. Perhaps there is an interaction with this file giving Find Address errors. I do not know. Giving up for now but will watch for other possible success stories.

sd maps should be in second page

Double surprise for me, these are the file names:

I don't know why the gmapprom1 didn't work for me during the first testing, but it does now.

The big surprise is the gmapsup1, which works only in the SD card.

Hint for others doing this kind of research: you can see at a glance in the folder which files have been recognised and which haven't. The unit creates .sum files for each recognised file.

catymag,

Thank you for your explanation. Something I have found after restoring 2011.20, the Inventory ASR Map line has a Check Sum that is NOT 00000000 as it was for the 2011.30 install. In addition, the Voice Check sum (.VPM File) and the ASR Language Check sum (.SRD file?) are the same for the working 2011.20 and non-working 2011.30 installations. And finally, there are four entries for ASR Maps that do NOT appear in the Inventory after the 2011.30 installation (all internal .SRD entries do show up in both installs and have the same check sums. Additionally, ASR files in the \garmin\asr directory on the microSD are not inventoried so possibly they will not work from the SD card... but the JCV Files were inventoried and will work from the card...

Could the ASR.RAR (ASR/SRX files) be bad or wrong for this unit? They were placed into the 885T's internal \garmin\asr directory when installed

Hi all, this is my first post here. Sorry for my english. In post 1 you say unrar and put the folder in the garmin maps. xp-c: \ Documents and Settings \ All Users \ Aplication Date \ Garmin \ Maps. or I have to create the folder Garmin and the folder Maps and inside this folder put the City Navigator NT 2011.30 or I have to put everything unrar
or just put the img folder.That more should be done.
Sorry I do not speak English and the Google translator I do not hear much.

Thanks

The folder should be already there when you have installed Mapsource.
Just go to your folder options in the Explorer, Tools -> View and select "Show hidden files, folders..." and untick "Hide Protected system files".
Thats the settings in Win7, XP should be similar.
Then copy the complete folder "City Navigator North America NT 2011.30.gmap" to this maps folder

Thank you very much for the reply, actually was there.

Hi,
I have downloaded and installed the mapsource version from Demonoid link, works fine after unlocking. However after transferring to SD card to replace the 2011.20 version my Nuvi 3790T says cannot authenticate maps. This is different from cannot unlock. Any suggestions as to cause and solution appreciated

I ran across this thread in the Tutorial section that might help with your issue:

[Only registered and activated users can see links. ]

"The solution is to remove the locking from your map completely with one of the unlockers."

In my Garmin 3790T i have installed 3 maps in SD card with names gmap3d.img (joined 3D maps for NA and EU), gmapsupp.img(3.4GB joined Na and EU map), and gmapdem.img(rec map3.01 of EU) and in the Setting>maps i see all pf them. I tried them and all are working.. BUT in the test mode I do not see dem map on SD but only the dem map of NA in main unit.. Any ideas??

Unlock the map with Fast IMG unlocker or Alternative Unlocker where both of them removes lock portions from img. Then it works, at least working for me all the time..

All the best.
