Re: DCM-300 Firmware update

I have emailed the request form with the serial numbers of all the DCM-300's that I would like updated to the latest version. I have waited more than 48hrs and the update has still not come through. Do I need full VRS RTK fix to recieve the new firmware or will it come through as long as my cellular data connection is good (which it is) I cant seem to find any useful information online and only heard about the request form from one of the Trimble trainers at a course I was at. Any and all information you can give me about this over the air update will be helpful thank you.
