to change the centrafuse logo, you can replace the existing "logo.png" with your one then it would change the logo. The reason to have a head deck, because the PC needs some sort of amplifier to drive the speakers, so I had two options, either to put in an amp or to get a head deck. And I chose the head deck because it gave me radio as well as it solved a lot of the engine noise problems. I think Dylan's LCD has a built in AMP, that would have been a nice unit to have too.
