iDatalink working with Toyota
iDatalink's rTO3 wiring adapter works in conjunction with iDatalink's Maestro ADS-MRR module (sold separately), allowing you to connect a new iDatalink-ready car stereo in select 2018-up Toyota-made vehicles. Once connected, you'll retain the use of your steering wheel audio controls and your factory amp in these vehicles. You'll also be able to keep your Toyota's vehicle settings personalization menu, auxiliary A/V input, and backup camera.
The package includes connectors that plug in between the Maestro module and your factory radio's wiring plugs. You'll have to solder or splice together this harness's power/ground, illumination, speaker, and navigation output wires to the corresponding wires on your aftermarket receiver's wiring harness. You'll appreciate the additional features added by the adapter, including the ability to view performance gauges and vehicle information on the new radio's screen.
