R4 Companion
A Bluetooth companion for compatible Uniden R4 and R4w detectors with GPS-based muting, alert detail and trip summaries.
Consider it only after checking your detector and firmware.
SpotLocks and configurable alerts bring detector information to the phone and supported CarPlay displays.
Keep in mind: Requires an R4 with US firmware 142 or R4w with US firmware 127 or later; signal filtering cannot guarantee threat detection.
