Net Radar kit (except the MRCD-only kit) already includes this GPS Module.
GPS provides speed-controlled radar mute as well as LID (laser interference defense) activation. It is very useful at suppressing K-band false alerts from automatic door sensors while driving at city speeds. Speed limit setting can be programmed by the user with a setup file created on alpupdate.com.
GPS module may be required for certain future laser sensor add-on for ALP.
