All our software is free. If you have v2.07 and want to upgrade, then you should be going to v2.13 which is on https://furunousa.com/en website under the NAVnet 3D model you have. Once on the model page, click on "view support/tech info" button to get the side with the software.I read that there is a free download of v2.12, but I cannot find it on the website. Any direction on where to find it?
