The MSHD9813SG is the Street Glide version of Diamond Audio's Plug N-Play Digital Media Receiver for the 1998-2013 Harley-Davidson Street Glide. Diamond Audio lists the Street Glide and Road Glide as separate part numbers, so order the one that matches your bike.
It retains the handlebar controls and includes AM/FM/WeatherBand, a backup camera input and a 2.1A USB charging input.
What HogPlay adds to your MSHD9813SG
Your MSHD9813SG 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 Diamond Audio 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 MSHD9813SG, 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 Diamond Audio MSHD9813SG is installed there's no factory radio left to unlock — the MSHD9813SG already does CarPlay itself. What HogPlay adds on top is screen mirroring and streaming, not activation.
