The 2004 Harley-Davidson Road King Custom struck a different pose than its bagger siblings — stripped-down front end, blacked-out finishes, and a lower, leaner stance built around the Twin Cam 88 engine that powered Harley's touring line through the early 2000s. It kept the Road King's signature detachable windshield and classic touring roots but leaned harder into custom style. What it never got was a factory radio or infotainment system. Riders wanting to run Apple CarPlay or Android Auto on this 2004 Road King Custom need to add it themselves — that's where the HogPlay Media Screen comes in.
No Factory Radio — Add Your Own Screen
The 2004 Harley-Davidson Road King Custom 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 Custom to split the difference between stripped-down cruiser attitude and long-haul touring comfort, and the Twin Cam 88 under the tank delivered the torque to back it up. It's a bike riders still hang onto for exactly that blend — but 2004 electronics didn't include any provision for a screen, GPS, or phone integration, so navigation and music have always meant a phone in a pocket or a separate mount.
The HogPlay Media Screen closes that gap without touching the bike's stripped-back look. The 7-inch display mounts to the handlebars, wires straight to power and ground, and runs wireless Apple CarPlay and Android Auto once it's connected. The mount is reversible, so it clears the way for the low-slung custom bars without ruining sightlines, and the whole install stays add-on rather than permanent.
Turn any 2004 Road King Custom into a connected ride with the HogPlay Media Screen. Dual Bluetooth means one channel pairs to your phone for wireless CarPlay or Android Auto while the second streams audio out to an auxiliary amp, handlebar speakers, or a portable Bluetooth speaker riding along. A built-in speaker on the unit itself handles turn-by-turn voice prompts and casual audio on its own, no external speaker required. Sealed and waterproof through and through, it's built rugged enough to shrug off rain, road grime, and everything else a custom Harley sees.
