Replace factory radio and retain OEM amplifier in many European Vehicles.

If unhappy with factory radio, you can replace it with an aftermarket radio or infotainment system while also retaining the factory amplifier. The ARH-RCA easily integrates factory amp to any aftermarket radio that has RCA Pre-Amp outputs. This harness is ideal for replacing radios with solid 20-pin ISO plug and radios with yellow 6-pin ISO plug.
Installation is simply and straightforward:
1. Simply disconnect the Solid 20-pin plug from radio and connect it to this harness
2. Connect the Male RCA's and remote turn on wire to the new aftermarket radio.
Most aftermarket radios include (4) 2 pairs of Preamp outputs, however if your new replacement radio has only (1) pair then (2) Y-adapters will be required. Please check your new radio prior to ordering.
