    Picking your brain since your the only one I know that's done this

    The wire harness, is there one major plug and all the wiring clipped to the ip will come out with it or do I need to undo each wire clip on the plastic ip and it remains in the carrier. So far trying to determine if the dash speakers and sun load sensor wire needs removed and unclipped or if it remains on the carrier while removing. Thanks!!!

    Re: Project HUD

    There really isn't much in the way of wiring that attaches to the instrument panel carrier. There are some hidden screws in a couple of locations that are a bit of a pain (park brake release handle bracket and a couple on the right side of the dash) but removing just the IP carrier should be as far as you need to go. Wiring stays pretty much in the car.

    As for removing the IP carrier, your best action is to remove the shifter and the steering column first. When the dealership replaced my HUD under warranty, they had to break sections of the IP carrier to get it around these. I'm still irritated to this day about how they handled this but there's not a lot I can do now. One thing you can try is to remove just the column to start. With it completely gone you may be able to lift the IP carrier up enough to clear the shifter.

    You should be able to make all necessary wiring connections with the harness and cast instrument panel structure in place. The carrier is very awkward so be sure to have an assistant to avoid damage to other interior trim.

    As for the components on the top of the dash, remove and unplug the speakers. Unplug the sunload sensor and unclip the wiring from the IP carrier. Just make sure when it all goes back together that wiring on top is exposed properly. You won't want to take it apart again to fish out a speaker wire. You will also need to pay attention to the IPM and bracket since these (as I recall) attach to both the IP carrier and the cast dash structure.

    1Bad,
    Just digging though this thread, and this caught my eye.
    If I want to add the Secure Car, what exactly do I need to do?

    Buy a 06+ rcdlr from a car with same options and do the 30 minute learn procedure.

    Re: Project HUD

    Update

    Non HUD dash can be cut to fit HUD, thus dashboard is NOT needed.

    Everything worked great other than the hud itself. It appears the refurbished HUD is a dud. It powers on reads all information but will not move or adjust with the toggle switch. It moves during initial power so the motor is good but it is not interpreting the switch command at all. Tested my switch on my dads car and it does in fact work so I know its not the switch. Wiring has been checked several times and short of completing a voltage check per Darcys help, I have written off the HUD as the issue. Car will remain in parts until the "NEW" HUD I just purchased off ebay for $100 this time (and it does state NEW not refurbished, HUD comes in).

    1Bad,
    Would you be willing to sell the refurbished unit? If so, how much? My adjustment mirror is warped and the plexiglass window is gone.

    Project HUD

    Did the display corner markings show up when trying to move it? Maybe the mirror is just stuck / off the track.
    Does the illumination change?
    If it moves during startup that sounds like it would be moving to a memory position ...

    The brackets showed up during power on. On initial tests it did in fact move in one direction but then stopped completely. The brackets appeared during that initial test but no longer appear only during the initial boot on start up.

    Sure am.

    It's in perfect shape other than the lack of response to the switch. Motor does work it moves up and down on start up but non responsive via switch.

    Re: Project HUD

    If they don't show during switch use than I'd have to say the HUD doesn't see the switch being active as they should come up any time it's moved.
    I assume you checked connection of the harness to the HUD ... Wonder if the traces on the circuit board or wires are broken inside.

    Yeah it sucks but I have no explanation for why it worked only in one direction then not at all after countless attempts to make sure there is good terminal connection at switch and HUD and running new wires between them there's nothing left for it to be. It DID work in the other direction per my helper for a few seconds but you had to hold the switch for several seconds then it would finally move.

    That's fine for my purposes.
    How do you guys usually arrange selling stuff? PM address and PayPal info?

    I dont THINK this was the issue because if memory serves me right the IPC was switching when selected however I will be PISSED if this was the issue...

    1. Driver Information Center (DIC) Switch Malfunction

    2. Head-Up Display (HUD) Malfunction
    Circuit/System Description

    The driver information center (DIC) switch is a multiplexed switch that functions as a DIC/dimmer switch. The DIC switch is also used for the head-up-display (HUD) (if equipped). The switch then functions as the HUD/DIC/Dimmer switch. The instrument panel cluster (IPC) only monitors the DIC switch inputs. The dimmer switch is monitored by the instrument panel module (IPM) and the HUD switch inputs is monitored by the HUD. Battery power is provided to the DIC switch via the instrument panel cluster (IPC). The IPC also provides the DIC switch with a low reference. The switch input to the IPC is pulled low or grounded when a switch is activated. The DIC switch is a momentary contact switch that connects a series of resistors in a resistor ladder format. The IPC monitors the DIC switch signal circuit to determine the DIC switch inputs. Each switch state - INFO UP, INFO DOWN, INFO RESET, ENGLISH/METRIC, TRIP RESET- corresponds to a certain resistance value. The IPC determines the switch pressed by the voltage drop across the resistors.

    The head-up display (HUD) is a display system that optically projects vehicle information onto the windshield. The HUD has an electric tilt adjust that is controlled by the up and down switches. Operating these switches directs the motor to move the HUD image up or down on the windshield. The HUD is equipped with a page switch that scrolls through multiple messages present on the HUD. The HUD is also equipped with automatic dimming. Dimming is controlled by the HUD dimmer switch. All three switches control the HUD by grounding the HUD switch input signals. The dimmer switch uses a variable resistor to control the intensity of the HUD display.
    Conditions for Running the DTC

    The ignition is in ACCESSORY or RUN.
    Conditions for Setting the DTC
    B3567 59

    The IPC detects that the DIC switch is stuck.
    B3567 01

    The IPC detects that the DIC switch signal circuit is shorted to battery.
    B3567 59

    The HUD detects that the HUD switch is stuck.
    B3567 01

    The HUD detects that the HUD switch signal circuit is shorted to battery.
    Action Taken When the DTC Sets
    • The IPC ignores the DIC switch inputs.
    • The HUD ignores the HUD switch inputs
