I have an 04 SVT with the audiophie head unit. The other day I turn the car on and the radio doesn't come on. So I press the power button and the radio reads 1 hour and turns on. However, when I turn the car off the radio stays on until I press the power button. Additionally my amp I have wired in doesn't power on and for some strange reason my gas gauge doesn't register for a minute. Any ideas as to what's wrong?
