I put a brand new xtron cd dvd plus navigation stereo in my infinity qx4 suv ut the dvd put a message that said dvd is disabled for your safety what can i do to resolve that
These DVD devices are defaulted to "off" while moving to comply with motor vehicle laws that prohibit a screen from being visible to the driver when the vehicle is in motion.
Typically, there is a wire that is connected to the hand brake / parking brake circuit. If the wire is connected to (+)12V *OR* (-)12V it will enable the DVD to play. Of course, connecting to the wrong one will instantly turn the player into toast.
Locate the wiring diagram for your model to find the cable associated with the parking brake circuit. With a digital voltmeter, set to DC Volts at a range closest to - but not less than 15 Volts DC. Black lead to the - jack and the red to the + jack of the meter. Touch the black probe to ground and the red to a 12V source. You should see a 12 to 15 volt indication. Reverse the probes and you should see the same value, but with a (-) indication. Now you know that black is - and red is +.
SET the brake and turn the DVD on and play. Touch the black probe to a good ground location. Touch the red probe to the brake wire. Note the voltage. It may be 11 - 15 V or 0 to as much as 2 volts. RELEASE the brake and repeat. The voltages should be reversed with the brake RELEASED. If the DVD played with 11 - 15 volts on the wire, connect it to a constant 12 V source. If it played with 0 to 1 or 2 volts, connect it to ground.
