RadioPRO RP5-GM61 Radio Replacement Interface - Retains OnStar & Bose

In this review the RadioPRO RP5-GM61 is evaluated as a practical solution for technicians and DIY installers who need a single module that preserves factory features when replacing the radio in select GM trucks and SUVs. The bottom line: it is designed for anyone who wants to keep OnStar retention, factory steering wheel controls and both standard and premium Bose amplifier retention without complex extra wiring. Installers will appreciate that it combines multiple retention and output functions in one preloaded package, cutting bench time and reducing configuration steps.

Key Features

• OnStar retention: Preserves OnStar functions so owners do not lose telematics access after swapping the factory radio.
• Steering wheel control retention: Keeps factory steering wheel commands working with the new head unit for seamless operation.
• Bose amplifier retention: Maintains output to both standard and premium Bose amps on MOST50 systems to avoid amplifier rework.
• Navigation outputs and chimes: Retains navigation output signals and warning chimes so turn-by-turn prompts and alerts remain audible.
• Backup system retention: Preserves park assist, backup sensors and backup camera feeds so safety systems continue to function.
• Data-controlled RAP accessory: Provides the accessory output needed for retaining radio accessory power and remote functions.

Who It's For

The RP5-GM61 targets professional installers and experienced DIYers working on compatible 2014-2019 Chevrolet and GMC models who need to keep factory convenience and safety systems intact. It is especially useful when replacing a factory radio in vehicles with OnStar, MOST50 audio networks or Bose amplifiers where preserving factory wiring and signals avoids additional harnesses or amplifier changes.

Buyers who only need a simple wiring harness without feature retention or those with vehicle years or trims outside the listed compatibility should look elsewhere; compatibility is specific and this module is meant for the models and model years listed in the application guide.
