BBWX Sirus Software Update

I have been able to update my TZT 9 and 14 with the new 4.01 OS.
I downloaded and expanded the TZtouch and BBWX Sirius update but have not been able to get it to load. I used the right slot as directed, even tried the left with no success.
All I get is a blank a.k.a. dark screen.
Am I wrong to do this on a BBWX 2? Any direction will be appreciated.
 
Normally the 4.02 software is provided and required for the BBWX3.
It is okay that you use it with the BBWX2 as long as your system has heading data. It does make some changes to the marine zone areas to adapt to changes made by NOAA. It is best to format the chip inside the TZT (using serviceman) before you place the 4.02 software on it (If using the full OS and APP upgrade). The full update requires the chip to be NTSF bootable format. The App only upgrade has be placed on a formatted FAT formatted chip. It might be best to call into our tech support guys if you continue having problems setting up the upgrade chip.
