Notes: The iDatalink Maestro HRN-HRR-GM2 installation harness requires the purchase of the iDatalink Maestro RR or RR2 (sold separately).

Head Unit Connection: The HRN-HRR-GM2 supports iDatalink's Direct T-Harnesses (sold separately) for direct connection to select iDatalink Serial Port compatible head units (including Kenwood, JVC, Alpine, Sony, and Pioneer radios) - 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-GM2 harness and splice each wire directly to the aftermarket radio's corresponding wire..

Flashing Module via Weblink Desktop: The iDatalink Maestro RR (ADS-MRR) 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. System requirements include -

• Windows PC (10/8.1/8/7/Vista/XP/2000) or Mac OS X (Mojave [10.14], HighSierra [10.13], Sierra [10.12], El-Capitan [10.11])
