Maestro RR and Maestro RR2 are both interface modules designed for car radio replacement, but they have some key differences:

• Maestro RR2 is the newer model, offering expanded compatibility with more vehicles and aftermarket radios.
• RR2 supports additional features like advanced vehicle diagnostics and more customizable options.
• Both modules retain steering wheel controls and factory amplifiers, but RR2 may provide enhanced integration for newer cars.
