yea I heard that too, and then the live feed stopped working as they were talking about the problem... freaked me out! But the feed is back on now.... Was the heating fixed?
(edit: the feed cutting was probably just me, just saying it was an unfortunate time for it to do so)
edit 2: They just said that the problem is specifically for the visor (to prevent fogging and icing), not the whole helmet... They still haven't found out what's wrong.
