Stilo DG-20 Digital Rally Intercom

Stilo DG-20 Digital Rally Intercom

The Stilo DG-20 is a digital rally intercom for teams that need clear driver and co-driver communication in a loud competition car. It combines dual independent digital noise cancelling, Bluetooth, selectable stage and road modes, direct camera connection and USB-C firmware updates in one 12V system.

It is a strong fit for club and national rally teams, gravel rally vehicles, and competitors moving to a more configurable digital intercom. If you are replacing an analogue intercom, confirm your helmet electronics, connector and radio or camera wiring before ordering.

Choose the correct connector

Select the connector that matches your helmet or headset. Connector errors are avoidable, so check the electronics fitted to the helmet rather than choosing by helmet brand alone.

• Stilo Male, AB0800, for Stilo WRC Venti, Venti4, WRC DES, ST5, ST6 and Trophy Plus helmets with WRC electronics
• Peltor Female, AB0810, for ZeroNoise, Sparco and Peltor helmets and headsets using a Nexus connector

Not sure? Send us a clear photo of your helmet connector, or contact Harris Race Radios, and Rex will confirm the correct option before you buy.

Compatibility

• ✅ Stilo WRC Venti, Venti4 and WRC DES, direct connection with Stilo Male
• ✅ Stilo ST5 F, ST5 FN and ST5 R, with WRC electronics fitted
• ✅ Stilo ST6 F, ST6 FN and ST6 R, with WRC electronics fitted. See the Stilo ST6 FN Carbon Helmet as one example of the helmet range
• ✅ Stilo Trophy Plus, with WRC electronics fitted
• ✅ ZeroNoise, Sparco and Peltor, via Nexus connector with Peltor Female
• ❌ Stilo Trophy Rally, non-Plus, not compatible

The DG-20 also works with a Stilo WRC Venti helmet when the correct WRC electronics are fitted.

Who is the DG-20 for?

• Rally teams wanting independent driver and co-driver noise control
• Competitors who want stage and road modes with camera integration
• Teams that need Bluetooth for setup or road communication, with it automatically blocked in stage mode
• Drivers upgrading from a simpler digital intercom and wanting USB-C firmware updates

The DG-20 is not the right choice if you specifically need a built-in GSM or SIM module. Compare it with the Stilo DG-30 Digital Rally Intercom for that requirement.
