Can you change the boot screen logo?

On the AVIN Avant 2 you can. Not too sure about the Avant 1. I have upgraded to the Avant 2 about 6 months ago and its great!

Thanks! Is it easy to add a subwoofer to the E53 with this unit? Is the X5 cabled already for a sub?

Another question regarding these new Android headunits... the screen angle. How is the viewing angle reflection compared to the stock nav screen? Does it have reflection issues? What part of the car is reflected in the screen based on the driver's viewing angle?
