The required radio interface module for running an aftermarket head unit on 2014 to 2023 Harley Touring
The iDataLink Maestro RR is the interface module that lets a modern aftermarket head unit, including the SoundStream V2 and WHD14+, communicate with your Harley-Davidson's factory systems. On a 2014 to 2023 Street Glide®, Road Glide®, Ultra, Electra Glide® or Tri Glide® Ultra, this module is required for full functionality and correct CANBUS operation. MAA pre-programs the module for your bike and radio wherever possible for a true plug-and-play install.
Harley Touring bikes run constant digital communication between the radio and the body control module. The Maestro RR is the translator that lets a new head unit join that network cleanly, retaining the functions you use every day.
Who This Is For
You are fitting an iDataLink-compatible aftermarket head unit to a 2014 to 2023 Harley Touring bike. Without the Maestro RR the bike will not recognise the new radio, so this module is required, not optional, for units such as the SoundStream V2 and WHD14+. If you want Bluetooth app updating instead of a USB connection, the Maestro RR2 is the alternative.
What This Is Best For
- Enabling an aftermarket head unit. The Maestro RR is the required module for SoundStream V2, WHD14+ and other iDataLink-compatible radios, translating between the radio and the bike's network.
- Retaining factory handlebar controls. Volume, track, source and menu functions keep working from the bars, and can be remapped with the iDataLink software.
- Correct CANBUS communication. It keeps the data flowing correctly to the body control module and infotainment network, which is what keeps the audio upgrade stable.
- Retained factory amp integration on compatible non-CVO models, so a factory amp build stays intact.
Maestro RR or RR2: which do you need
The RR and RR2 have the same core function. The Maestro RR is flashed and remapped over a USB connection to a computer, and remains the standard, most-used option for motorcycles, especially when MAA preconfigures it before shipping. The Maestro RR2 adds Bluetooth update support through a smartphone app, which is convenient but not required on a bike. For most Harley installs, the RR is the right choice.
The Bottom Line
The iDataLink Maestro RR is the module that makes an aftermarket head unit work on a 2014 to 2023 Harley Touring bike, keeping factory controls and correct CANBUS communication. If you are upgrading the radio, it is required. Add it to cart above with your compatible head unit such as the SoundStream V2, and choose the RR2 if you want Bluetooth updating.

What the module does
The Maestro RR sits between the aftermarket radio and the Harley network. It translates CANBUS data so the radio and the body control module understand each other, which is what retains handlebar controls and keeps the system stable. In practice: the new head unit behaves like a factory-integrated radio rather than a disconnected aftermarket box.
Programming and setup
The module is flashed with your Harley profile before install. MAA pre-programs modules for customers wherever possible. To flash it yourself: connect the Maestro RR to a computer by USB, go to maestro.idatalink.com, select your bike model and radio, and flash the module.
