JCV files

 

I have a 55 LM
My GPS comes with Junction view.
What is the extra "JCV" file and do I need it?
What would be the benefit of downloading it?
And last, how much room does it take on the GPS?
Thank you for any help ypu could give me.

The Large JCV file is not compatible with the Essential Series nuvis (3x, 4x, and 5x). Thanks to Factory member Strephon_Alkhalikoi for this important piece of information. If you have one of these Essential Series nuvis, do not try to use the Large JCV. If tried, no Junction Views will appear.

Thanks

for the link for the explanation of large JCV
