Removing the navigation and DVD player from the Acura TL is fairly simple to do and can be accomplished in less than a half an hour. The navigation and DVD player are part of the car's head-unit (radio/stereo.) The car will not have any stereo function if it is removed. Always disconnect the car's battery before working with its electrical system. This will prevent the system from shorting and damaging electrical components.
Locate the edges of the dash trim panel. The dash trim panel will end around the radio. This panel needs to be removed in order to take out the radio. There will be a small gap where the panel ends. Insert a flat head screwdriver into this gap and gently pry back the dash. The dash trim panel should start to come off. Repeat this prying action every few inches along the dash trim panel until it is sufficiently loosened so that it can be removed by hand. Use caution and go slow.
Unscrew the four screws holding in the DVD/Nav. Once the dash trim panel is removed the screws holding the unit will be visible at the four corners of the radio. Once the screws are removed, pull the radio out.
Unhook any wires in the back of the radio. The wires will be attached to the DVD/Nav with clips. This makes the task easier as they can simply be unclipped. Pull out the antenna wire from the DVD/Nav. The unit has now been removed. Install a new head unit or reattach the battery cables to turn the car on.
