Large JCV File For 2019.30 Map

Thanks for posting the large jcv file so quick. Greatly appreciated by everyone who still need it.

Okay, it's downloaded as an RAR file (D3060280A.rar). What do I do with it now?

You will need to unzip the file. There are a number of Zip/Unzip software utilities, many of them free. I use WinZip, which is not free but you can download it and use it free for 30 days. 7Zip is a free one I believe. Depending on your Microsoft operating system, you might have a built-in utility.

Put the downloaded zipped JCV file in the folder you you want. Right click on the file and choose "unzip here", "unpack here" or "extract here" depending on the utility you use. Voila!

I use 7-Zip. It is a free open-source software.

My Win10 laptop does come with built-in zip/unzip utility.

Downloaded twice, tried to extract with 7zip (as I have done in the past) and met with the dreaded "Cannot open RAR file as an archive"

Something is corrupt as I have done the very same thing a number of times before without any issue.

Downloaded on Chrome and Firefox -- same results. IE will NOT let it download - too big

Download WinRAR from rarlabs.com and use it to open the file.

My .JCV file is 847,857 KB. That sound right?

WB, the file as I downloaded it was indeed named D3060280A with a file type of "WinRAR archive". WinRAR.exe handled it and created the file D3060280A.JCV.

Phil

Downloaded with Chrome, Win10. Extracted with 7zip as D3060280A.jcv, no issues.

compressed, D3060280A.rar, file size: (635,695,428 bytes)
expanded, D3060280A.jcv, file size: (868,205,210 bytes)

Downloaded 7Zip version 18.X and installed. I had V9.2 that I have used for years without any issues. That fixed my problem.

The Zip/Rar compression must have changed headers and my version couldn't use it. That would cause the error saying the file was corrupt.

7Zip works on both Win 7 and Win 10. Upgrading to Win 10 is not an option for me.

Where do you find the .JCV file on the GPS?

Under .sys file folder from the root on the main Garmin unit. JVC file folder will be listed under a separate subdirectory in .sys. The actual JVC file is inside the JVC file folder

.sys is a hidden system file folder so you have to change your file manager settings to allow for viewing any hidden file folders. Be careful.

I must have had a brain cramp when I wrote the above reply. Instead of my using WinZip, as stated above, I always use WinRAR.

Thanks, but have view hidden files/folder, and to view protected systems files. Still can't see the .sys folder.

If you use an SD card, your computer will show the Garmin internal storage as one drive and the SD card as a separate drive. Check and search all of your computer drives/disks and you may find the files you are missing.

Thank you from a user who prefers the large full screen jcv file.

Some thoughts:

Have you switched the device from MTP to MS mode?

To see protected operating system files, it's necessary to uncheck, not check, the box as the default is checked to hide them:

If the GPS device has a SD card present, confirm that you're looking for the .system file in the device, not the SD card.

Good luck.

PS: for future searches for JCV files at The Factory, be sure to type JCV, not the electronics manufacturer JVC. I pretty sure that I've typed it incorrectly in the past as have others.

Tested the file this morning, works just like it's supposed to. Thanks again.

a member going to the effort of allowing other members to be able to download this file.

But my 2797 and my new 50 Lmt-HD cannot make use of it. My 855 does, but too much effort for a now completely backup related GPS as well as unreliable GPS.

Absolutely agree. A big thanks for the hosting of the large JCV file that comes with each map upgrade.

Also, thanks for the patience with my problem of late. Must be a bit more diligent on upgrading older programs.

All's well that ends well.

Yes, did uncheck the box to view system files.

Did not know about the MTP vs MS mode. Will have to find how to do that one.

Found it, Thanks. My .JCV file is only 497K. It is in an RV660 and RV770. Guess I'll try the larger file.

You can try the Large JCV file but you may want to read the Large JCV FAQ first:
