Update 23/02: Incorrect Wiring Diagram Label on AHF-510, AHF-610 and AHF-710 American Hi Fi Head Units
Please note that the wiring diagram labels are incorrect for the 510, 610 and 710 head units. The label currently indicates that the 12V red wire is also ‘Memory’. This is incorrect. The 12V yellow is ‘Memory’ as this has constant 12V power therefore is responsible for holding the units presets and station settings. If you have any questions, please call American Hi Fi on 0800 348 6346.
