I have the adapter for motor coaches and bought it 6-13-21 through Amazon.  It has worked great and still is, but I keep getting a notice to upgrade the firmware.  It looks like some adapters need to be sent in to update the firmware.  Questions:
1) How do I find out what version of firmware my adapter has?
2) If I send it in, about how long will it take to get it back?

Thanks
