It is the same model, HM700E and U,
the only difference is the label of the Cam,
the firmwareupgrade is for both.

Only you must check that you got the
newest model build after the end of june2009,
but the older HM700 cannot updated by yourself.

Thanks Eric!

About firmware update.
In JVC Professional Europe - Landing the firmware update link :
JVCPro-MSIS

"For older versions than 1.0.6 please check black balance."
How to do that ?
My camera running 1.0.5 version.
The JVC dealer in Greece said to me that this is a new update, and it will not create problem to my camera.
JVC EUROPE it does not answer to my emails.....
I can make the update?

I got it done. I had an older version.. But I had to takle it to my local technician... He managed to do it.. How.. don't ask me... He left me saying "Oh.. these cameras are all programmable chip based.. You can even make a coffee machine out of it!"

HM - could we hope to get a new firmware with the new sister of the HM700
to get a better picture quality, lower noise, frame-recording, sd-recording and some more else,
it will be a nice information for the users from the expo in Las Vegas.
But I don't think so.

My 700 was firmware version 1.0.5 I had to return it to JVC London where they did the upgrade within an hour at no charge. Later versions of Firmware can be downloaded from JVC Europe site and can be done by the user.
The update allows recording in MP4 format, allows the use of class 10 SDHC cards and reduces the visual noise in low light recordings (though I can say I've seen much difference).
