The 2004 Harley-Davidson Road King (FLHR) paired with a sidecar is old-school touring at its most distinctive — full-dress classic styling, a chrome front fork, and the torque-heavy Twin Cam 88 engine pulling the extra weight of the rig with room to spare. Sidecar rigs like this one were never fitted with a factory radio or infotainment display, so riders and passengers rode in silence. The fix is the 7-inch HogPlay Media Screen, a bar-mounted unit that brings wireless Apple CarPlay and Android Auto to this 2004 Road King sidecar setup.
No Factory Radio — Add Your Own Screen
The 2004 Harley-Davidson Road King with Sidecar (FLHR) 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 Road King's blend of touring comfort and stripped-back styling made it a natural base for a sidecar conversion, and the Twin Cam 88 underneath delivers the low-end pull that hauling a sidecar demands. What it never had was a way to run navigation or stream music for the ride — the FLHR left the factory with analog gauges and no screen of any kind.
The HogPlay Media Screen mounts to the handlebar in clear view of the rider, keeping both hands free for the extra steering input a sidecar rig requires. Installation is straightforward: run power and ground to the battery, and the unit is ready to pair. It's fully reversible, so nothing about the 2004 FLHR's stock wiring or bars is permanently altered.
