The 2004 Ultra Classic With Sidecar (Japan) is a late-run version of the base-radio era, still built around a full fairing and a sidecar for serious cargo and passenger space. The factory 99-05 base radio does its job for AM/FM but has no Apple CarPlay, no Android Auto, and no screen. HogPlay's aftermarket radio path adds both wirelessly.
No Factory CarPlay — Add It Your Way
The 2004 Harley-Davidson Ultra Classic With Sidecar (Japan) shipped with the factory factory touring radio (1999–2005) — a solid unit in its day, but no Apple CarPlay, Android Auto or touchscreen. Fit an aftermarket CarPlay radio (SoundStream, Rockford Fosgate, Boss, Diamond Audio or Aquatic AV) for wireless Apple CarPlay — SoundStream, Boss and Diamond Audio include Android Auto natively, while Rockford Fosgate and Aquatic AV gain it once you add a HogPlay Media Box or Piglet, which also unleash Netflix, YouTube, streaming apps, Mirror Link and AirPlay. No headset bypass needed — that's a factory-radio thing, not aftermarket. Rather not swap the radio? A bar-mounted HogPlay Media Screen adds wireless CarPlay and Android Auto too.

By 2004 the Ultra Classic With Sidecar (Japan) formula was well proven - fairing for weather, sidecar for cargo, and a factory 99-05 base radio that covers the basics without any phone integration. There's no CarPlay, no Android Auto, and no touchscreen on this dash as it left the factory.
Riders wanting real phone integration usually go with an aftermarket CarPlay radio - SoundStream and Aquatic AV both offer units built for open-air installs like a sidecar rig, with wireless Apple CarPlay and Android Auto onboard.
With a new head unit in place, a HogPlay Media Box adds Netflix, YouTube, YouTube Music, and podcasts from an SD card or USB drive, and a USB Piglet adds Android Auto plus Mirror Link or AirPlay mirroring. A bar-mounted Media Screen is an option too for riders who'd rather not replace the radio.
