Will fish mapping be supported on the TZT? I currently have the bbwx3 I know I would have to upgrade to the bbwx4. Before I purchase the bbwx4 does anyone know if the TZT will support the fish mapping. Thanks in advance.
The Fishmapping with Sirius (BBWX4) will only be available for TZT3 and TZT2BB but unfortunately, it will not be compatible with TZTL12F/TZTL15F and TZT1 series.
For TZT, it won't happen and TZT2 is unlikely to ever see it either. Fish mapping will likely be a TZT3 feature only, due to the memory and processor requirements.
