some of you remember i wrote a diy last time about installing this unit, i finally finish mounting it, i make a trim ring out of abs plastic and fill the extra space and i put it below the radio using the coin tray spot. the coin tray/lighter lid still functional, meaning i can close it when i don't need to play with it. but still accessable without reaching too far when i need to, i think this is the best spot for it. matching my alpine units buttons perfect:
