I will be in for a AI-Net one providing its easy to program on the pc end

(using vb)
From what I have read with AI-Net it should be possible to send data from pc to the HU and show graphics? and then send FF/REW commands from the HU to the PC to change the track?
Also I have read all the pages (skipped a few lines here and there) but didnt really see anything on audio input through ai-net, it is going to have an aux audio input function right?
Good luck with the projects mate
