Flash the Factory Radio
Integration technology allows the DSP to reflash the factory radio for a flat response curve, without the need for external equipment. This reduces the cost, saves time, and allows installers to provide better service with complete control over the upgrade.

Designed for easy integration with aftermarket or factory audio systems and easy expansion with amplifiers or other devices. Refer to the vehicle applications tab or chart for more information.
The Saddle Tramp DSP is a device that allows a user to flash the Harley-Davidson® radio to a 4-channel, flat audio output curve; but when the device is connected, it locks itself to the vehicle’s identification number (VIN), saving the last known state of the radio into memory. In order to unlock the Saddle Tramp DSP and use it on a different vehicle, or return it, you must remove the flash from the motorcycle, returning the radio back to factory settings. This can only be done 3 times in total. In the event that this product needs to be returned to the manufacturer, it cannot be locked to a motorcycle’s VIN.
Built-in Integration and Easy Installation
