The WHD.9813 is Soundstream's upgrade head unit for the 1998-2013 Harley-Davidson touring series. It replaces the factory radio and installs into the OEM fairing using factory mounting hardware and the original AM/FM antenna — no brackets or antenna adapters. The display is a 7.7in HD widescreen Quantum Film LCD with a capacitive touchscreen.
Phone projection is already handled by the unit itself. HogPlay's USB Piglet adds Mirror Link and AirCast screen mirroring, and a Media Box adds streaming apps. A bypass adaptor is for factory CarPlay radios and has no role once a WHD.9813 is fitted.
What HogPlay adds to your WHD.9813
Your WHD.9813 already does wireless CarPlay and Android Auto, so you don't need us for that. What it can't do is stream: a HogPlay Media Box adds Netflix, YouTube and other apps straight to the screen that's already on your bike.
A USB Piglet adds Mirror Link and AirCast screen mirroring — putting your phone's actual screen on the dash, which no head unit does on its own.
A bypass adaptor doesn't apply to a SoundStream unit: a bypass unlocks a factory CarPlay radio, and yours has already replaced it.
What each part does
USB Piglets
A USB Piglet plugs into the head unit's USB port and adds Mirror Link and AirCast screen mirroring — mirroring your phone's actual screen to the dash, which no head unit does on its own.
Media Boxes
A Media Box adds Netflix, YouTube and other streaming apps to the WHD.9813, running them on the screen you already have.
Why there's no bypass adaptor here
A bypass adaptor unlocks a factory CarPlay head unit. Once a SoundStream WHD.9813 is installed there's no factory radio left to unlock — the WHD.9813 already does CarPlay itself. What HogPlay adds on top is screen mirroring and streaming, not activation.
