Software Update Procedures

PLEASE READ BEFORE UPDATING SOFTWARE IN YOUR
NAVNET TZTOUCH2 MFD
Only update software while in port, never while underway. Do not attempt
to update the software the same day you are planning on using the
equipment.
Software version 6.21 update requires a reset to the internal sounder as
well as a Master Reset to the MFD. You need to save all valuable user
data prior to updating the software, such as; waypoints, routes, tracks
and user settings.Instructions for saving user data can be found in
chapter 8 of the Operator’s Manual, chapter 6 of the onboard eGuide, and
in the NavNet TZtouch2 Exporting and Importing Points, Routes, Tracks,
and Settings document found in the manuals sections of the TZTL12F and
15F.
This update should be done with any additional MFDs turned off.
Note: Total time for the software update is approximately 30 minutes
1. Download the software from the Furuno website to a folder on your
desktop.
2. Once you download the Zip file from the Furuno USA website you will
need to extract it. Once extracted, the result will look like the picture
below (containing two folders).
When you open the first file, Part 1 containing the updated OS
(operating system) and App (application) you will see the contents
below.
3. Transfer these files to the root directory of a formatted (not to exceed
32GB) micro SD card. There should be nothing else on the micro SD

card that you are transferring these files to. After the files are
transferred, set this program micro SD card aside for now.
4. Now open the contents of the second folder, Part 2. You should see
the same contents as below. Transfer these folders and files to the
root directory of a USB Flash drive. Make sure it is a clean Flash
drive (nothing else on it).
These folders and files contain updated, internal sounder software,
world base charts, world 3D data, world satellite photos, eGuide, US
SiriusXM Marine Zones, and new Canadian SiriusXM Marine Zones.
Note: Due to the internal sounder update, both Part 1 and Part 2
updates must be completed. Do not update Part 1 without then
updating Part 2.
5. With the MFD power off, remove the microSD chart card from the
rear slot.
6. Insert the microSD software update card (Part 1) containing the OS
and App into the rear slot of the TZTL12F/15F.

The screen is then replaced by the normal TZtouch2 startup screen

The yellow progress bar along the bottom will travel across the
screen. When it gets to the righthand side, the screen will go dark. At
this stage, the power key is GREEN.This indicates that the
TZTL12F/15F is still in an update process.

After approximately 4 minutes, the unit shuts completely down. This
is indicated when the power key turns from GREEN to ORANGE.

Part 2 of TZtouch2 version 6.21 software update
Part 2 of the software update process contains world base charts,
world 3D data, SiriusXM US Marine Zones, SiriusXM Canadian
Marine zones, POI data, internal sounder update and eGuide.
1. With the TZtouch2 MFD powered off, insert the USB flash drive (Part
2) containing the following files into the USB pigtail cable on the back
of the MFD.
2. Insert the USB memory into the TZTL12F/15F USB port as shown
below.
3. Power the MFD On.
4. Shortly after a short beep, the progress bar will disappear and then
the installation will start. You will see the following notices during the
installation. The entire update for Part 2 will take about 10 minutes.

For approximatly the first 3 minutes, various world charts and data
will load.

Then after approxamtly 3:30 minutes, you should see the following at
the bottom of the screen: Chart copy data succeded.

Then the internal sounder will update. This section of the update
takes approximatly 4 minutes.
Internal sounder update succeeded

Then the manual (eGuide) is updated.
At this time the unit will fully boot up.

5. Remove the USB memory from the TZTL12F/15F USB port.
6. Perform a reset to the internal sounder per the instructions below.
7. Perform a reset to the MFD per the separate instructions.
Repeat the above process for other TZtouch2 MFD’s in the system.
Important:
You must reset the internal sounder. Failure to do so will cause a
communication error between the new internal sounder software and the
updated OS and App software.
To reset the internal sounder menu.
While the unit is on,
•Press the home button
•Press the settings tab
•Press the sounder tab

•Make sure the Fish Finder source is set to the internal sounder of the
TZtouch2 MFD that you are updating. It should not be set to a black
box sounder, such as a DFF1-UHD, DFF3, or to another TZtouch2
display in the network.
•The internal sounder menu settings are not saved when you save
“User Settings” in the file menu. Record any customer sounder
settings to re-install them after the software update is complete. We
recommend taking pictures of the sounder menu.
•Scroll down to the bottom of the sounder menu and select “Set
Hardware To Factory Default”. Then select OK to reset the sounder.
•Turn the MFD off and back on again to fully initiate the sounder
menu reset.
Although not a requirement, it is a good practice to fully reset the machine
via the Service Man menu (or power up reset) after the update process has
been completed. Please see “TZT2 Factory Reset Procedures” or the
instructional video (TZTL v6.21 Software Update Video) which explains this
process.
