R4 Companion

CarPlay Support!

NOTE: R4 Companion™ requires a Uniden R4 or R4w radar detector with US Version 139 (R4) or 125 (R4w) firmware to function correctly. R4 Companion will NOT function correctly without at least this version of firmware.

R4 Companion™ is a feature rich app, designed to give you the most out of your R4, while enhancing your driving experience along the way. Featuring intelligent alerts and advanced muting! R4 Companion™ is the COMPLETE solution to enjoying your R4.

SpotLock 2.0 and Advanced False Assist 3.0. Both data driven systems have been updated using 5 years of historical data. This takes your detector to a whole new level of quietness and safety against real threats.

The R4 Companion™ app leverages years of optimizations and features from the Radar Companion™ series of apps. (Available separately for owners of the V1, R8, R9, & DS1 radar detectors).
