The RC-GZ1 is a universal remote control engineered as a direct substitute for Roku model 3226000173, offering seamless compatibility across Roku Streaming Stick+, Roku Ultra, Premiere, Streambar, and Roku TVs from TCL, ONN, Hisense, Sharp, and other manufacturers. Voice control functionality enables hands-free content search, channel launching, and menu navigation, while standard controls manage volume, input switching, and app access through simple tap or voice commands. Setup requires only battery installation, pairing button activation, and Roku device power-on for automatic recognition. The RC-GZ1 replaces legacy models RC-FA5, RC-AL5, RC-AL2, RC-FA1, and RC-81, though app shortcut button configurations may vary by unit.
