【Abstract】Due to external reasons，vehicle front windshield film，installation of non-original driving record equipment，etc.，it is easy to cause vehicle navigation and positioning lag and deviation，affecting the user's car experience. According to the principle of vehicle positioning，this paper investigates and analyzes the ability of vehicle multimedia to search for stars and interact with satellite data，as well as the stability and reliability of the signal，and solves the problem of poor signal.

【Key words】navigational positioning;front windshield film;signal interference
