The warning message may have been useful!

People don't realise that factory car audio is operated by and monitored by the Body Control Module (BCM) on a computer network. Your warning chimes and indicator clickers are generated by the BCM and played through the car audio system. The computer has no idea that this new device is!

Take it to an auto electrician or to an Alarm / Audio installer and see if their professional bi-directional grade scan tool computer can reprogram the BCM to ignore your device. Or just put the old one back.

MP4 is a codec that is not compatible with this DVD player. Your DVD player will play store bought DVDs just fine. Please read the specifications in the owners manual to see what codecs are compatible with your player.

can someone tell how ?

this use to be simple for most units and yes it would work, however, manufactures became wise to this idea and placed a relay inside the unit that must be reset to prevent us WISEGUYS from doing so, but i do not know if this is the case with yours, if it is then you can run a toggle switch between the unit and the ground in order to reset this relay as needed with a flip of the switch
