How to sync TZT 2 and a TZT 3 to show same route

Entanglement

On previous boat we had NavNat 3D connected to several monitors so the same chart/route would appear on them. Now have 12" TZT2 on fly bridge and 16"TZT3 in pilot house. Routes and tracks created when operating from pilothouse don't appear on TZT2. Are they totally independent or can one be a slave to the other?
Thanks in advance and I hope I didn't make a mistake getting the TZT.
 
Are the two units networked together via N2K or Ethernet? Look in the Sensors list, should show both devices on one or both network options.

Also, report back your software versions for both the TZT2 and TZT3. I seem to recall reading here that the TZT2 needs to be at a certain SW version to properly network with TZT3.
 
The TZT2BB (v9.56) should be on the latest version of software, as should the TZT3 (v3.56). Keeping these up to date will make sure that they are operating at their peak capabilities!
