    You might try entering your VIN on this site:
    https://tis2web.service.gm.com/tis2web
    and see if you have an option to view if there is any information about your radio on it.
    You may find something useful on it but you may not; since our units are updated via CD and tech 2 is just needed for some controlling I don't believe it will show up here.
    (The Escalade however apparently does list the radio / AMP in here and they can get some updates to fix certain things)

    This is the list of modules I was able to get from my VIN:
    >EBCM Electronic Brake Control Module
    >ECM Engine Control Module
    >ESCM Electronic Suspension Control Module
    >ONSA TIS2WEB Pass-Thru OnStar Activation (Replaced/Upgraded units only)
    >TCM Transmission Control Module
    >TVT TV Tuner (Export Only)
    >V.T.D. Vehicle Theft Deterrent Learn
    >VDAAW Vehicle Direction Alert Alarm Warning

    ... interesting, two 09 models that have matching numbers don't work.
    (doesn't matter that one is V and one is not, they should be the same NAV unit)

    Re: No NAV With HUD

    Mj caddy i have the same exact versions, same year car, same issue. We definitely need firmware updates. Unfortunately we need to convince a dealer of this because there is no tsb stating ours needs to be updated. I found a dealer finally. It's an hour away and they're open Monday to Friday. They close at 5. Doesn't go well with work. Ill keep you guys posted.

    Idea

    Clear your firmware manually then it should accept any firmware as its not updating it your simply giving it new firmware. The problem using the known tsb it won't allow the update if your firmware is the same or higher. If it has NO firmware then I would assume it would take it.

    Only issue I see with this is its my understanding lane departure and blind zone are turned on and off through the nav. The 05-07 cars never had this option so the firmware may not contain the ability to adjust those features (on or off) if this works....

    Hmm, hadn't really thought about that being the issue... I just assumed it would display whatever came over the serial data line.

    I cannot seem to find a pinout of the HUD that shows what wires are connected to it, did ddalder provide you with one from your HUD project?
    You mentioned needing to relocate a PIN from the XLR HUD harness to work with the STS HUD...
    Did you test out the nav features with your HUD?

    Guy, do any of the other display abilities fail to work?

    Code:
    Head Up Display (HUD) Description and Operation 
    
    The reconfigurable head up display (HUD) is an active matrix color display system that optically projects critical vehicle information through the windshield. 
    The head up display is controlled by a combination switch located in the vehicle center console:
    
    Image Up/Down Switch-The HUD image adjustment switch allows the driver to vertically adjust the images on the windshield up or down. 
    The HUD image position on the windshield can be personalized for Driver 1, Driver 2 and Unknown. 
    The vertical image position set by the various vehicle drivers is saved and recalled next time they drive the vehicle. 
    Moving this switch directs the motor to move the HUD image up or down on the windshield.
    Power/Dimmer Switch-The brightness of the HUD image can be adjusted by pressing the knob on the center of the DIC control panel in until it pops out and then pull the knob until it is completely extended. 
    Turn the knob clockwise or counter clockwise to increase or decrease the brightness. 
    If the knob is turned all the way to the left, the HUD will turn OFF. 
    On vehicles with adaptive cruise control, if the HUD is turned OFF, the cruise control will be inoperative.
    
    
    Telltales 
    
    The following is a list of telltales and gage information displayed in the head up display (HUD) and received via the serial data circuit:
    
    Vehicle Speed
    English/Metric Mode
    Turn Signals
    High Beam
    CHECK GAGES
    Tap Up/Tap Down/Upshift
    Adaptive Cruise Control Warning Symbols
    Warning Messages 
    
    The head up display (HUD) will temporarily display certain warning messages as it receives a serial data message from the responsible source (module). 
    The HUD displays certain warning messages received from the following sources:
    
    Adaptive Cruise Control Messages
    Radio Information
    Cellular Phone Information
    HVAC Information
    Turn-by-Turn Navigation Display (if equipped)
    Arbitrary Text Displays

    That is correct, the bottom two buttons on the left side of the config screen are dedicated to the SBZA and Lane Departure enable/disable functions.

    Re: No NAV With HUD

    I assume thats in the firmware then and not an auto detect feature like with Magnetic ride.

    Daddler did I THINK if he did it would be in the HUD thread. I know there were several different HUD part numbers like with the radios. My HUD came from an 06 and was re-manufactured before I bought it for the $30 bucks so its essentially new.

    I bought it for the Speedo and Tach while it would be neat if the directions display as well I wont cry if it doesnt.

    Re: No NAV With HUD

    Hmmm I wonder if there was a different HUD for non-nav equipped cars?
    I can't imagine that you could get HUD without NAV though.

    Re: No NAV With HUD

    You can't get HUD without nav.

    My HUD shows everything else just fine.

    There is an other thread with 3 09 sts drivers with the same issue and their problem was solved with a firmware update.

    I doubt it's in the HUD itself.
