first thing to do is backup your dash as it is now, in case all goes tits up

next bung a live game in and update your dash so it is live enabled, then follow the tutorials.
i am fairly new to this and it seemed so bloody complex i almost gave up, however after doin it once it is quite easy

and addictive fiddlin
i used motogp 2 to update my dash ( you do not connect to net with box to do this )
