Alpine H/U + Alpine H510 + AI-net=?

i currently have a alpine 9852 (not ai-net) and i wanna upgrade to something higher end. i was gonna originally get an eclipse or kenwood double din with built in sound field control but they're kinda expensive. the thing is that i want to have that processing but theres a problem. i just thought about getting another alpine ai-net h/u and hooking it up with my h510 processor but i dont know what i can control with it.

is there somewhere i can look to see how i can control the processor through the ai-net?

i already have the h510 but the controller isn't fully functional. i dont know where to find another controller and i want to know if i can control the different sound field's (hall, church, live, etc.) without the controller.

help?
