Review on Universal Radio Replacement and Steering Wheel Interface - Maestro ADS-MRR Enhanced for SEO by Flex Graham

Installed in a 2008 Buick Enclave with standard audio, the HRN-RR-GM5 Wiring Harness (sold separately) works fine with the idatalink Maestro RR module. All steering wheel controls are functional and programmable, the On Star system can be started, the car's XM antenna seems to work with the aftermarket head unit, I can view the vehicle stats on my display and the door/turn signal horn has been restored. I am using this kit with a Pioneer AVH-W4500NEX head unit. The only criticism of the module is the use of the long-dead mini-USB connector for the programming interface. It's 2019, why are we still dealing with the old flimsy plug?
