K40 Radar Detectors and Detection Systems Compared

K40 documentation covers the portable RLS2 and professionally installed RL200di and RL360di systems. Decide first whether you want a windshield-mounted unit or a concealed installation.

Brand overview

This K40 radar detector guide compares documented model names rather than claiming to list every product the brand has made. The RLS2 is described in its manual as a portable all-band radar and laser detector with GPS technology; RL200di and RL360di are installed systems with different receiver arrangements.
