The GPS antenna is highly important for wireless Pioneer AV receivers as this assists the system in accurately locating position when using Apple CarPlay or Android Auto. On navigation models this is also used for providing location data when using the on-board mapping system.

The GPS antenna should be located on top of the dashboard, with a clear view upward through the front windscreen. If the GPS antenna is installed under the dashboard and/or obstructed from clear view, it may result in inaccurate or failed GPS location data.
