The MSHD9813RG is Diamond Audio's Plug N-Play Digital Media Receiver for the 1998-2013 Harley-Davidson Road Glide. It replaces the factory radio in the fairing of the earlier bikes and brings a modern touchscreen and wireless phone integration to them.
Audio processing is handled on board: a 10-channel DSP with time delay and crossovers, plus six independent EQs and ten channels of clip-free output to feed amplifiers.
What HogPlay adds to your MSHD9813RG
Your MSHD9813RG 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 MSHD9813RG, 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 MSHD9813RG is installed there's no factory radio left to unlock — the MSHD9813RG already does CarPlay itself. What HogPlay adds on top is screen mirroring and streaming, not activation.
