Thread: City Navigator® North America NT 2012.20

There is a lot of info here on jcvs and the size and features. I have a 1490T that appears to load images more slowly than my 265WT, and it seems that the large image file sizes (image of North America) load slowly. My solution is to have two versions loaded; a local "few states" version, and the entire map. The few states version is used for most driving.

This leads to a question - Do the large jcv files appear to affect performance of any of the users devices?

The higher end garmins may have faster processors, but in my looking that is not clear, but the 1490 screen redraws and loading is slow.....

An answer to the image loading might help some decide which jcv to use...
Update - After loading the 700Mb jcv file and the smallest one on the sd card with NT in main memory, I cannot detect a file load time difference....Also in another experiment with multiple versions of NT on the sd card and memory, each detects the proper jcv with several jcvs in the same directory!
