No that is not the way that you install the Official Android market on the Arnova 10G2.
You need to install a custom firmware as this tablet is not officially certified by Google so that is why you do not have any Google Market or any of the Google services like You Tube, Gmail, Google Plus, Maps etc.
Please see link for firmware installationhttp://www.arctablet.com/blog/forum/arn ... -and-root/
I have the installed this firmware on my tablet from the UK and can confirm it works, It is a first release of the firmware and is been tested by the firmware makers and obviously the people who have installed it. So the firmware will be improved as time goes on.
