Description
Soundstream Reserve HDHU.9813RG — 7-Inch 1998–2013 Road Glide Head Unit
The HDHU.9813RG is the earlier dedicated Soundstream platform for a 1998–2013 Road Glide or Road Glide Ultra. It gives the bike a factory-location 7-inch touchscreen with Apple CarPlay, Android Auto, Bluetooth, SiriusXM readiness and camera support without turning the fairing into a generic-radio conversion.
The vehicle-specific fit is a big part of why it makes sense: the prewired harness is included, factory mounting bolts are reused, the OEM antenna connection stays in place and supported handlebar controls are retained. Its IPX5 faceplate/glass is also designed for the rain and wash exposure a touring-bike radio sees.
For the audio system, HDHU.9813RG provides 4-volt front, rear and subwoofer RCA outputs. Soundstream also publishes a 2-ohm-stable four-channel amplifier at 50 watts per channel and a built-in graphical EQ. USB supports 5 V / 1.5 A charging plus MP3/WMA/AAC/FLAC playback from media up to the published 64 GB limit. A camera RCA input with 12-volt trigger is built in.
The main comparison is WHD.RG, which Soundstream identifies as this radio’s successor. WHD.RG moves to wireless CarPlay/Android Auto and 5-volt preouts. One limitation applies to both platforms: HDHU.9813RG will NOT activate OEM Boom amplifiers, so a factory-amplified bike needs its amplifier path planned before the radio is ordered.

RADIO / OEM FUNCTION FIT
Where this fits in the build
The source unit has to fit more than the dash opening. Steering-wheel controls, factory cameras, amplified audio, chimes, USB, vehicle settings and data integration can change the correct installation path.
Plan aroundConfirm dash fitment and the factory features that must remain.
Match itMatch the radio to phone, camera, audio and interface requirements.
Finish itUse the correct vehicle interface instead of sacrificing OEM functions unnecessarily.
