I have two GY HD 100 European cameras and one BR HD 50 European.
JVC have offered to the US models a software/firmware update.

I have tried to see on JVC European home site but there no update available - is it because that not necessary?

Hi Flemming,

It's best that you take contact with your local dealer.
My HD100E did had two updates, firmware and hardware.

what do u they update Hardware for the JVC HD100e? I only heard about updating sofware of the HD100. Thanks
