Help Guide In-Car Receiver XAV-AX4000 The position accuracy is not good when using maps with Android Auto. Check the location where the GPS antenna (aerial) is installed. Some types of front windshields (windscreens) block GPS satellite radio waves. In that case, install the GPS antenna (aerial) near the window. Do not paint the GPS antenna (aerial). It may affect the accuracy. The correction status of the internal sensor may be insufficient. Moving your car to a location where no obstacle blocks GPS satellite reception as well as turning left and right several times may improve the performance of the internal sensor. 5-035-405-11(1) Copyright 2022 Sony Corporation 113
