Diamond Audio MSHD9813RG Harley Radio Upgrade for 1998–2013 Road Glide

If you're still running the factory radio in your 1998–2013 Harley Road Glide, you're dealing with outdated technology that limits your entire audio system.

Weak output.
No modern connectivity.
No real control over sound.

The Diamond Audio MSHD9813RG upgrades your Road Glide with Apple CarPlay, Bluetooth, and improved signal performance—giving you the control needed to build a real motorcycle audio system.


Why Factory Harley Radios Hold Your System Back

Factory radios from this era:

  • lack usable output power
  • have no Apple CarPlay or Bluetooth
  • limit speaker performance
  • produce weak signal for amplifiers

Even upgraded speakers won’t perform properly without a better source unit.


What the MSHD9813RG Fixes

This radio becomes the command center of your system:

  • Apple CarPlay integration
  • Bluetooth audio and hands-free calling
  • improved signal clarity
  • modern touchscreen interface
  • better control over your system
