Installed the Pioneer DMH-2660NEX with the Maestro RR on my 2015 non-JBL application. I also purchased the wiring harness, all the appropriate adapters, to include the. $200 HRN-RR-TO1 Interface and a Free SOTS Air Freshener. HRN-RR-TO1, USB and antenna, and the Metra 95-8235 Dash Kit. iDatalink Maestro RR (sold separately) enables the retention of the factory steering wheel audio controls, factory amplifier, secondary displays and can even display vehicle information (performance data, climate controls, battery voltage, etc.) when connected to compatible vehicles. *Available features may vary depending on the vehicle.
