I have a 2002 ford focus that came with the 6006 cd changer. I recently replaced my HU with the blaupunkt and followed the wiring instructions that are found on here. The radio works perfectly except for one minor problem. When i turn off the car, the radio completely turns off and loses all power. So the clock has to reset itself when i turn on the car again. Is there a way to have power going to the radio even if the car battery is off? Is it possible to have the radio working even if i dont turn the car battery on, just like the 6006 which will turn on for like an hour without the key in?
