I wanted to triple check all my settings and now more confused.
It doesn’t look like the TZT2 and TZT3 share tracks. So my TZT2 was still recording tracks, Yes, the track is on land in the pic, all displays were on and sounder was on standby, boat was on the trailer. I primarily use the TZT2 as the sounder. It also only has 900 track points.
The TZT3 still had track recording turned on but was not recording, it reached maximum points but looks like it was deleting the oldest because it has 29,XXX points recorded.
I think you are probably right there is some software bug somewhere especially since the TZT3 had recording turned on but was not recording. Are the TZT2 and TZT3 able to share tracks between units? Everything else seems to share between the units.
Thanks for your help.
