    Protocol used by my stock Clarion HU?

    Hey all,

    I have a 2008 Impreza. How can I figure out what protocol my stock head unit uses? I want to communicate to it (control the display, and track button input if possible). I know people have done this with other units / protocols (Alpine mbus, etc)

    Here's the pinout for the unit:

    model: 86201FG640
    part: PF-2950A-A

    I couldn't find anything =/
