Instruction: The number of the radio navigation system according to the spare parts catalog is on a sticker on the body of the radio navigation system! When replacing the radio navigation system, be sure to include coding to make it difficult to use in case of theft. Be sure to communicate the new code to the client. If the security code is not known, it can be requested via known systems. When requesting, the identification number of the radio navigation system must be given. It is located on a sticker located on the side of the device. The identification number is duplicated on the side wall of the radio navigation system. When installing a radio navigation system from one vehicle to another, make sure that the radio navigation systems of both vehicles have the same part number. Otherwise, malfunctions of the navigation system occur, since the setting of the selsyn sensor (angle sensor) radio navigation system will not match the vehicle. The radio has a permanent security code that prevents it from being used in case of theft. When repairing or troubleshooting, use the PAE 5051 tester or the VAS 5052 tester or their later modifications in the guided fault finding mode. The steering angle sensor must be adjusted for the navigation system to work properly (indicate the position of the device relative to the car body). When replacing, install the instrument with the correct part number. Installing another device will cause the navigation system to malfunction. After connecting the battery, it is necessary to check the vehicle equipment (radio, clock, electrical equipment of comfort systems). When installing magnetic antennas on the roof of a car, there is a high possibility of interference in the operation of the compass module due to the influence of the magnetic field and the constant magnetization of the roof. For complaints of inaccuracy or incorrect operation of the compass module heading indicator, the customer should be asked if the customer is using a magnetic antenna before starting repair work.




The RNS 300 radio navigation system combines the functions of a navigation system with a high-quality RDS radio. The two-din housing of the radio navigation system contains: an RDS radio receiver, a 5.8-inch monochrome display, a navigation system with a GPS receiver, a CD player for audio and navigation system. The radio navigation system RNS 300 has 4 speaker outputs. The CD player can read navigation system CDs or play music CDs. During music CD playback, the navigation system operates with a limited range of functions.

Instructions: In addition to regular audio CDs, CDs with MP3 files can be played. Playing music CDs with a diameter in cm (minidiscs) impossible. Mix CD playback (CDs containing computer data and music) impossible. To expand the functions, connectors are provided for connecting a CD changer and a telephony system. An antenna built into the glass is used to receive the radio signal. The navigation system uses a rooftop antenna. The radio antenna is not diversity.
