So idatalink had me disconnect my radio fuse and flash my maestro rr. Kenwood dmx706s head unit. After flashing it. I have no radio or maestro power. Connected red wire from Kenwood to yellow wires to see if the radio would get power at anytime, it does. So crutchfield sent me a new maestro unit. Same exact thing no power. Amp fuse on truck is good, radio fuse is good, Kenwood fuse on back of radio is good. Inline fuse on the maestro is good. Any ideas what could be blown or what's going on?
