just fitted mfd2, help please.

Hello all,

just fitted an mfd2 into my 2007 vrs, all is looking good so far, it works fine etc, even getting some info on maxidot from satnav but will post pics up soon.

My question is, is it worth updating its soft/firmware in anyway?

and can I change the vw logo on boot up to a skoda one?

and where can I get these things from? Download and burn a disc?

cheers for any help guys and girls.
