Adding a TZT2 to TZT system

Here is what I have, and don't want to run into any issues:
TZT9"
Airmar GH2183 (Heading and GPS for TZT, NMEA 2000)
Lowrance Link-8 (NMEA 2000, AIS turned off, DSC only, probably swapping for a Icom 506)
DFF-1
TM260 transducer
DRS4D
Hub-101
IF-NMEA2K2 (brings in AIS)
PSU-012
FA-150 AIS
PG500 outputing AD-10 into FA-150
GP-32 output second GPS into FA-150
Standard Horizon GX1250 with GPS input from the GP-32

I want to add in a 15.6"TZT2, keep the 9" as a dedicated finder screen, but want to know if the 9" will display the rezboost from the TZT2 or will I have to keep the DFF-1 on the system?

I also want to add the Airmar weather sensor, is it working with the TZT yet?

Anything else I should know?

We have seen some initial growing pains on mixed systems. I would wait for next software update to come out before building a mixed system. The TZT can use and control the sounder built into a TZT2. The Airmar weather sensor is supported as long as it is on the main 2000 bus. The radar Canbus connection is not currently supported by the TZT2 (but is expected to in the future).
