are you using the D2D wiring connection from the DEI? im sure DEi hasnt added this to their units yet. They have datalink connection (4 wires) but no D2D yet. Only audiovox has thid and still didnt prefect it. major bugs. I suggest you jgojohn to just wire everything without the purchase of any modules. Just pick up the Fortin Bypass (HONDA-SL3, or SL2 which is discontinued but some places still go them) its about 30 CAD so prolly cheaper in the states.
