The 2003 Harley-Davidson Road King (FLHR/I) rolled out in Harley's 100th-anniversary year, powered by the fuel-injected Twin Cam 88 that gave the big touring twin smoother cold starts and steadier low-end pull than its carbureted sibling. Fitted with a sidecar, this Road King trades cornering lean for three-wheel stability, hauling extra gear or a passenger rig behind that same 88-cubic-inch V-twin. What it never got from the factory is a screen — no GPS, no CarPlay, nothing. The HogPlay Media Screen fixes that: a 7-inch bar-mounted display bringing wireless Apple CarPlay and Android Auto to this 2003 Road King.
No Factory Radio — Add Your Own Screen
The 2003 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.)

The Twin Cam 88 arrived in 1999 as Harley's replacement for the Evolution big twin, and by 2003 it was a well-sorted powerplant — the fuel-injected FLHRI version starting easier in cold weather and running cleaner than the carbureted FLHR. Bolted to a sidecar, that torque-heavy V-twin has to work a little harder hauling three wheels instead of two, which makes the 88-cubic-inch engine's low-rev pull especially useful on a rig like this.
Mounting the HogPlay Media Screen doesn't touch any of that. The unit clamps to the handlebars in clear view of the rider, wires straight to a switched power source and ground, and is fully reversible if the bike ever goes back to stock. No dash cutting, no splicing into the factory harness — just a 7-inch screen bringing modern phone mirroring to a sidecar rig that predates it by two decades.
Built for a rig like this 2003 sidecar-equipped Road King, the HogPlay Media Screen pairs two Bluetooth channels at once — your phone for wireless Apple CarPlay or Android Auto on one, an auxiliary amp, handlebar speaker, or portable Bluetooth speaker on the other. A small built-in speaker covers turn-by-turn voice prompts and light audio on its own. And since sidecar miles mean more open-road exposure, the housing is fully sealed, waterproof, and rugged enough to shrug off whatever the weather throws at it.
