D4P control unit must be installed close to the car radio unit place as we usually read the required information from the CAN BUS radio (infotainment). However, in some vehicles such information may not in radio or do not enter it but MOST CAN information. In this case the vehicle should look in the database D4P car to check the connection points.
Remember that the information BB.DD. of D4P is constantly updating and which complements the universal information shown in the installation manual. In the event that the CAN BUS is not present on the radio and also not report on its connection point or unknown, please contact us via tikets system so we can provide extended information about the connection. Remember that you need the SERIAL NUMBER of your D4P control unit to request such information.
