One day while toying with a V-XTL5000, it occurred my power cable was disconnected, the part from the fuse to the rest of the cable that goes to the SAE connector. Well anyways, the radio works fine when control head has constant, ignition, and the radio itself isnt powered. BUTTTT when I power constant, ignition (control head), Constant, Ignition, (mobile), it causes the car accessories to stay on? does the CAN cable send power?
