Alright, so every time I plug my radar detector into the cigarette lighter it blows the fuse. This only happens after I've re-started the car, meaning I can unplug it and plug it in later without a problem if the car has stayed on the whole time. I've replaced the fuse twice now, and I wondered what the deal might be, if anybody had any ideas? The radar detector (passport x50) works fine, and the cord is still intact and everything.
