Medtronic Guardian transmitter updates

Not sure if this has already been posted (my basic search across the forums didn’t bring up anything by way of solution, although a number of us have suffered the problem described below), but I just found out about it from my CDE and thought I’d share:

if you are using Medtronic’s 670 system and are experiencing frequent and close in time requests for BG updates from Auto-mode right after you have calibrated the sensor or otherwise entered a BG, you might be able to fix the issue with a free upgrade of the transmitter which the company offers.
