COG Vector on TZT13X

Hi everyone,
I recently replaced my old Furuno TZT12F with a TZT13X, keeping the SCX-20 compass.
However, I noticed an annoying difference: on the new unit, the COG vector only appears when I'm going over 1 knot, whereas on the TZT12F it was visible even at very low speeds.
For me, it's essential to always see the COG vector because I do a lot of drift fishing, so the actual movement direction (COG) is different from the heading line, and I need it to properly understand the drift.
Has anyone else experienced this?
Is there any setting to change or a way to force the COG vector to display even below 1 knot?
Thanks in advance for any tips!

I also do a fair amount of drift fishing over structure. Although my TZT3 does show the COG vector, I find that turning on the track display with a short time based recording interval is a much clearer way to see exactly how the boat has drifted and makes it very easy to repeat a drift if it was productive. The "Fish It/"Drift It" feature is supposed to do this for you but I have never bothered to figure out how to use it!
 
COG is only valid when moving 3kts or better. It's possible the software in the TZT13X makes the COG vector line disappear when it's not valid. If it's not that, please check Home-Settings-Initial Setup-Data Sensors-Data Sources to ensure that the SCX20 is selected as the source for position, COG/SOG, magnetic variation, heading and date & time.
 
Thanks! I double-checked, and the SCX20 is correctly selected as the source for position, COG/SOG, magnetic variation, heading, and date & time.
However, I'm still unsure how to view the direction of movement (COG or similar) when moving at speeds below 1 knot — is there any way to visualize this at low speed, or is it simply not available due to TZT XL limitations?
 
There isn't a way to show valid COG if moving under 3kts. That isn't a Furuno limitation, that's a GPS limitation. Other companies may mimic COG under that speed, but it's not correct. The only other option is heading which probably isn't helpful for what you're asking for.
