Thanks for JCV (Junction View) for nüvi 37xx units - (D2504020A.JCV - 526 MiB uncompressed). My 3790 unit download from Garmin only JCV for other units and it works bad.

Sorry, but I'm novice to Garmin (used to be a tom tom user...): the problem I have is that on my device intl memory there are 4 img files (gmapbmap.img, gmapprom.img, gmaptz.img, gmap3d.img) but in my downloaded file I can only find 2 img files (gmapsupp.img, gmap3d.img). How do i rename gmapsupp.img file? and what about the new gmapbmap.img, gmapprom.img, gmaptz.img files??? where/how can I get them?? Thanks for your help once again
gmapbmap.img is the base map, leave it like it is
gmapprom.img is the preloaded detailed map ,your CNEU old map: the one you must substitute-gmapprom.img is the right name
gmaptz.img is the timezone map, leave it like it is, I think is always the same
gmap3d.img is the 3D buildings map, subsitute it with the new one
all the files you need are in post one

pallexl-
From what I understand about the the 3790 as well as my 885T, the .SRD files stay as is and only the .ASR and .SRX files need updating to coincide with the new map(s). If you get errors doing a Find Address using Voice Commands you have something wrong, even though most or all other Voice Command functions may still continue to work properly.

ok, thanks. I have loaded 2011.30 to MapSource, made my selection of maps, transfered to my device, renamed and unlocked the new image and then reloaded into the .system folder. In addition to this step I have replaced asr+srx files and 3D image and all other relevant files found in the 2011.30 install package - now map functions works fine, but for some strange reason some of the voice commands don't...I'm getting technical fustrated - any help is appiciated :-)
Well, the ASR files in post 1 may be for the 885T or the 3790, I can not tell and no one has indicated which unit as well. The size, 727mb, does not tell me as I do not know which size goes to which unit. If they are for 885T, they will not work in the 3790 as far as I know and the reverse seems to be true as well. We need someone with knowledge in this area. For certain, if you have voice command errors, one set of files is wrong or they are not installed in the correct place. I think you installed the gmapprom by downloading the mapsource files? Not sure that will work with your voice commands, it would not for my 885T. I had to install the entire locked image (this was for NA CNNT 2011.20 since .30 ASR files do not seem to be around as yet so I can not test this newer update) file complete for NA CNNT, unlock it using a key and then and then only would my voice commands work for Find address. Do not know if this is applies to the 3790 but would assume it does.

Thanks Mikie - your help is appriciated. Can I ask one more thing? How do you make this step "I had to install the entire locked image (this was for NA CNNT 2011.20 since .30 ASR files do not seem to be around as yet so I can not test this newer update) file complete for NA CNNT, unlock it using a key"?
I think what you are asking is the step by step for getting the entire locked image in Post 1 into your GPS? D/l the image. uncompress it. rename it to gmapprom.img if different. Hook up the gps using a usb cable. using Explorer or some other File Manager to get to the 8xx gps \garmin sub dir or 37xx .system directory. Copy the gmapprom.img on your GPS to somewhere on your computer hard drive so you have a back up copy of it. Once copied, then copy the new gmapprom.img you uncompressed back to the 8xx GPS \garmin directory or 37xx .system directory. It will ask to overwrite. Tell it yes. Once the file is copied to your gps, use a text editor like notepad to create "gmapprom.unl", an empty file on your PC. Then, using jm keygen v1.5, enter your GPS Serial Number in the top block, press Generate block midway down, then drop down to next block where it asks for what map, go to bottom map name drop down block, and hit "other", a block pops up and then you enter 2281 into this block (this mapset ID), hit enter, press generate block near bottom, copy and paste the serial number from the very bottom block into the gmapprom.unl file on your PC Copy this file to the same place you sent the new gmapprom.img file on your GPS. Done. Disconnect GPS safely. Map should now be unlocked and function OK when you turn GPS on. If all is well, map comes up meaning it is successfully unlocked, then try using voice command to Find Address. If GPS says locked map when starting up, then redo the key gen steps.. you entered incorrect serial or map id... If Find Address gives an error, then there are errors to look at like incorrect ASR files, and other things that seem to go wrong with these voice units.
