What the AI looks for in Car Audio & Video Input Adapters

Available factory port
Interfaces that plug in behind the radio need a CD-changer or satellite port on your specific radio If your radio does not have that port, the adapter cannot connect.
Exact vehicle and radio fit
Match make, model, year and radio type, including premium audio The protocols for these interfaces differ by manufacturer and by model year.
Inputs added
Choose AUX only, USB, or Bluetooth depending on what you need Bluetooth versions cost more, but they avoid having a cable hanging in the cabin.
Cassette or other last-resort inputs
Use cassette adapters only when the car has nothing but a tape deck They are cheap and they work, but they wear out and are noisy.

Brands that matter

  • GROM Audio: Vehicle-specific USB, AUX and Bluetooth interfaces.
  • USA Spec: Long-established factory radio interfaces.
  • PAC: Integration and input interfaces.
  • Metra: AUX and integration harnesses.

What to avoid

  • Universal input adapters that do not name a supported vehicle list
  • Splicing into factory wiring when a plug-in interface exists for your car
