Head Unit Connection: The HRN-HRR-TO1 supports iDatalink's Direct T-Harnesses (sold separately) for direct connection to select iDatalink Serial Port compatible head units, replacing the wiring harness that comes with your aftermarket stereo (some hardwiring may still be required). If connecting to an aftermarket head unit that does not support an iDatalink Direct T-Harness, you'll need to cut off and remove the 20-pin black connector from the HRN-HRR-TO1 harness and splice each wire directly to the aftermarket radio's corresponding wire.

Flashing Module via Weblink Desktop: The iDatalink Maestro RR or RR2 will need to be loaded with correct firmware before installation. The included USB cable plugs into your computer and allows you to "flash" the Maestro RR with the appropriate firmware to prepare it for installation. Simply download Weblink Desktop (for Windows and Mac) onto your computer to access the appropriate firmware.
