The 1998 Ultra Sidecar picked up the factory-cut batwing radio pocket this year, making the media upgrade on this three-wheeled tourer more direct than its predecessors. A Diamond Audio MS-HD9813 or Soundstream SG-V2 / WHD.9813 fits that 1998-2013 opening without an adapter kit, unlocking wireless Apple CarPlay and Android Auto on a bike far older than any factory touchscreen. A HogPlay Media Box behind it brings Netflix, YouTube and more to this sidecar rig.
Headset Bypass Required
The factory radio locks CarPlay behind a paired headset. A HogPlay headset bypass removes that so CarPlay and the USB port work without one — then a Media Box or Piglet adds wireless CarPlay, Android Auto and streaming apps.
