The 2004 Harley-Davidson Road King (FLHR/FLHRI) paired with a sidecar turns Harley's classic touring cruiser into a three-wheeled family hauler, its Twin Cam 88 rumbling through wide-open highway miles with the stability only a sidecar rig delivers. Chrome spoked wheels, a wide front nacelle headlamp, and that fork-mounted windshield define the era — but like every 2004 Road King, it rolled off the line with no factory radio or infotainment. Bolt on the HogPlay Media Screen and this sidecar rig gets wireless Apple CarPlay and Android Auto for turn-by-turn navigation and music on every ride.
No Factory Radio — Add Your Own Screen
The 2004 Harley-Davidson Road King with Sidecar (FLHRI) left the factory with no radio, stereo or touchscreen to bypass — so instead of a workaround, you add your own. A standalone HogPlay Media Screen is a 7-inch head unit with wireless Apple CarPlay and Android Auto, live Maps & Waze navigation, calls and streaming built in — we recommend the Screen 7 Pro with its onboard DVR drive-cam. Most riders settle for Bluetooth-only kits that leave the phone in your pocket with no turn-by-turn directions; this puts it all on the bars instead. It mounts to the handlebars with basic power and ground and comes off just as easily, so reach out to the HogPlay team if you'd like a hand. (Media Box support on Screens is in development.)

Harley built the Road King as the purist's tourer — minimal fairing, spoked wheels, and a wide, comfortable saddle — and the Twin Cam 88 supplies enough low-end torque to pull a sidecar without strain. Add the sidecar and the whole riding dynamic shifts: three-wheel stability, added cargo capacity, and a rig built for relaxed, steady mileage rather than lean-in cornering.
The HogPlay Media Screen mounts straight to the handlebar, keeping the Road King's classic cockpit uncluttered — no dash cutting or wiring harness surgery. Just two wires run to power and ground, and the mount is fully reversible, so the 7-inch screen sits upright and readable no matter how the bars are set up.
Beyond CarPlay, the HogPlay Media Screen runs dual Bluetooth: one channel pairs your phone for wireless Apple CarPlay and Android Auto, the second feeds an auxiliary amp, handlebar speakers, or a portable Bluetooth speaker. A built-in speaker handles turn-by-turn voice prompts and light audio on its own. And since this 2004 Road King sidecar rig sees real weather, the unit is fully sealed and waterproof, built rugged enough for the road.
