i just bought a 2005 mdx with stock head unit and speakers. The radio will start soon as I start the car, and will run up until I either 1. Roll down a window, or 2. Touch the brake. The radio will then turn right back on once I release the brake or the window switch. It does this when I am driving as well as in park, when I am driving, I noticed the blinkers also cut the radio off for a short amount of time. What is the solution to this?
