My new Sena Prism WiFi will not format or recognise my SanDisk Extreme PRO 64 GB microSDXC Memory Card.

This card is brand new, already formatted and writable from Windows, but the Sena device will neither format nor recognise it.

Audible error message is "no SD card".

The card itself is obviously a popular quality card and in working condition.

The camera's firmware is up to date. Version 1.1.

On a side note the Android app is pretty pathetic and rarely connects to my phone.
