GPS antenna is required for Radar Integration or the use of the new ALP TX Sensors. If you have a newer HW2 CPU (Manufactured Mid 2014+) then you can
connect a GPS Antenna directly to the G Port of your CPU. If you have
an older 2013-Early 2014 HW1 CPU a RG2 or RG3 module would be needed to connect the GPS antenna. If you purchase the radar option the RG Module is already included in the radar add-on package.
