I have panasonic touchbook cf-31 devices that seem to be having issues with windows location services getting updated GPS data from the sierra wireless em7355 chip.

The driver is from 6/4/2015 version 15.6.1030.19. Windows. thinks that is the most updated version for the device. How can I verify this or find if there is an updated version? The sierra wireless website and panasonic website are very convoluted.

Any help is much appreciated.
