Thread: City Navigator® North America NT 2012.20

it is so big because it has full screen high res landscape images for all junction views instead of portrait, so it takes up double the space

I see no reason for the images to be high res in the D3060030A.jcv. Our maps aren't high res so neither should be junction views.

It is also more than double the size of the Junction View for the 2012.10 release (D3060020A.JCV). I almost wonder if it contains both portrait and landscape views of each junction? Good news is it displays undistorted junction views on my Kenwood DNX9960, so I'm happy! Possible bad news for the future is the DNX9960 has 4GB of flash, but with everything increasing in size for this release there is only a few 100MB left... if this trend continues there is going to be trouble.

So I assume it's safe to say the 752 MB D3060030A.jcv will give me the most junction views and the clearest images
on my 765T, but paying the price by doubling the size of the file.

I'd say that's a reasonable assumption, but its pretty hard to know for sure. What we need is a program to look inside .JCV files to see what they actually contain instead of just installing and hoping for the best.

I doubt there is a program that can edit .JCV files, more likely an expert in computer progarmming would ne needed.
I'm just grateful that Garmin decided to provide the file for older units.

Problem: Unlocked North America will not install. Symptom:
Error reading from file .\Product1\00382879\I07F61BB.GMP

If I ignore, I get it again on a different directory.

What I did:
1) Windows 7 Home Premium that is 3 days old - I am trying to slowly replace an older Vista machine that is having some problems.
2) Installed BaseCamp
3) Installed MapSource 6.1.3
4) Renamed executable and copied patched version
5) Downloaded the 4 part UNLOCKED NA 2012.20 from links in the first post of this thread with no apparent problems
6) Downloaded the installation portion from a link in the first post
7) Tried extracting with WinRAR - but failed
8) Successfully extracted all 4 parts with WinZip (trial) to c:\maps\ by only selecting the .ZIP file
9) Successfully extracted the 2 installer files to C:\maps\City Navigator North America NT 2012.20.gmap\
10) Run the installer

Note that on the older computer I successfully installed and used the 2012.10 North America - but I used LOCKED files. And Fast Image Unlocker.

Q1) Did I do something obviously wrong?
Q2) Is it worth trying with the LOCKED files and unlock them post installation?

Please full mapset torrent WITH msi updater / installer!
Thanks!

I found my problem. It was that I unzipped the 2 installer files to the wrong directory.

I incorrectly installed *in* the directory .\City Navigator North America NT 2012.20.gmap

After I reread *carefully* I moved the 2 install files to the directory that contains .\City Navigator North America NT 2012.20.gmap (1 level UP)

Success. And thanks for the support!
