Everything worked as it should. I thought I would install a aftermarket Bluetooth stereo. I ordered the complete dask kit including harness I cut nothing. I removed the stock Head unit and installed the aftermarket Pushed the power up button and nothing. I was puzzled so I checked all fuse nothing was popped. I put the stock Head unit back in and no power. I went to pop the trunk by the key fob and nothing same with the gas door windows will not roll down but they light up at night I was driving and no high beam's. I feel I triggered the Theft system by removing the stock unit. A handful of U codes came up Any help will be gratefully appreciated. Thank you Tommy.
