2nd Station upgrade issue

[scoffer]

I upgraded my Ray60 to version 1.35. I just purchased an new Ray Mic 2nd station and tried to get it to upgrade as well by putting the radio in to the boot loader mode and 2nd station mic into programming mode, then re-flashing 1.35. Upgrade appears to go through, 2nd station mic screen flashes at a faster pace after the MFD shows the upgrade is 50%, which, according to the instruction video Raymarine posted on YouTube, implies that the Ray60 update is finished and 2nd station is updating. Upgrade completes successfully according to the MFD. Ray60 boots right up and is at 1.35. Second station just stay blank with back light on, and periodically flashes off then back on (similar to programming mode, but a different pattern). Only way to get the 2nd station to power off at this point is to disconnect it from the Ray60.

I have gone through this process multiple times, but still cannot get the 2nd station to work, just a blank screen with the back light on.

Is there something I'm missing? Do I have to turn something on in the Ray60 menu to enable the 2nd station?
