NN3D Route Upload and updates

[rdykstra]

Hello, just bought a boat with NN3D and a TZT MFD. Trying to make this system work for a bit while we figure out a suitable replacement and have TZiboat as a backup. Tried to upload routes in gpx and in csv formats. It recognizes card but says no files found when I try to upload routs in the menu. I searched the forum for posts on topic but nothing specific. I used GPSExplorer and several other conversion sites to convert from gpx to csv. Any help is appreciated.
Also, where can I get the most current software update and map uploads? I saw some posts where there were free updates but the links in those posts go to discontinued Furuno web pages? Thanks in advance for any help

The NAVnet 3D uses a combo of 4 csv files with specific names and columns. There are probably more conversion programs that will work, but the one I know of for sure is Andren Seamarks. More information about that can be found at https://seamarks.biz/

Also, depending on the version of software, the max size of SD card is either 2GB (for v2.05 or lower) or up to 32GB for v2.07 or higher. The MFDBB controller (MCU001) is limited to a 2GB SD card no matter what version of software.

GPX file could be used on TZT MFD with max SD card size of 32GB. Some converters GPX files seem to have a problem, but the Seamarks program has one that works.

The software can be found on https://furunousa.com/en under the model number of the unit you are trying to update. When you get to the product page for that model number, click the View Support/Tech Info button...the software and instructions are at the bottom of the page.
