1. Try the Eject Button: First, ensure you've tried the normal eject button multiple times. Sometimes a slight bump or jiggling of the player can help dislodge it. Turn the truck off and on again, sometimes a power cycle helps.
2. Check the Manual: Your owner's manual *might* have instructions for a manual eject procedure, though this is uncommon in factory-installed units.
3. Professional Help: If the eject button doesn't work, your best bet is to take your vehicle to a car audio specialist or a qualified mechanic. They have the tools and expertise to safely remove the CD player and retrieve the disc. Attempting to force it yourself could damage the player or the CD.
Important Note: Avoid trying to pry the CD player open with tools. You risk damaging the stereo system and potentially injuring yourself. Professional help is the safest and most reliable solution.
