I downloaded large JCV file in (4) parts from post on this forum...how do I go about assembling these 4 zipped files into (1) useable file I can load to my 1490LMT ?
I unzipped the 1st one, and that automatically assembled the .JCV file without my having to act on the remaining 3 .zip files.
On page 2 member rookie8155 suggested the following;"install 7zip or WinRAR program on your computer and then double click on the archived file. It should combine all fragments into one file. Just save it and use."
Thanks for your prompt reply.
I downloaded 7Zip then went to folder where I downloaded all (4) parts of large JCV file. I used 7Zip to extract file. Did I do this right ??
The file size I end up with for D3060180.B is 834,575KB.
Does this look right or did I mess up ?
U did done right !
Thanks for confirming...I finally managed to do something right on the 1st go-round.
I've loaded large JCV file to my Nuvi 1490LMT and all appears well...whew !
Curious if you or any other Garmin GPS techies know why Garmin took such a large departure from their normal file numbering system for this large JCV file ??
Sure was a lot was a lot easier when Garmin provided the file. Not like it costs them anything to post an already existing file to their site.
There was a flaw in the initial version of the map. When the map was reissued, the JCV was renamed to distinguish it from the earlier version.
Are you suggesting that if one was an earlier updater to 2016.10, it should be reinstalled to avoid the flaw whatever it may be ?
There was an initial version of 2016.10 that was released to testers. That version is the version that was readily pirated in the weeks/months leading to the release of the official map. There were flaws in that testing release which needed to be corrected. That is why 2016.10 was delayed so long.
The JCV file for that release was named D3060180A.jcv. The version that goes with the official release is D3060180B.jcv. The mess with the JCV file for 2016.10 is partly because there were two versions of it. Many people, including myself, attempted to use the "A" JCV file from that pirated tester release only to find out later that Garmin revised the JCV file as well.
Garmin has to bear some responsibility here for not staying the course and continuing to offer the large JCV file for people who wanted it, but ultimately it boils down to people not knowing that the JCV file changed.
