The Metra WM-CR10 is a short antenna adapter cable that lets an aftermarket radio plug into the factory antenna in select 2002-up Chrysler, Dodge, Ford, GM and Jeep vehicles. One end is a male Motorola plug for the new radio; the other is a snap-lock female connector for the factory antenna lead. It is a fit-and-forget part rather than a performance upgrade, and its job is the same as other brand-specific antenna adapters: match the two connectors so the factory antenna keeps working. Owners rate it well for doing that job simply, though a few report loose fits or a weak signal in some vehicles.
