2 days ago, I turned my car off, hit my power button on my radio to listen to it with the car off. 20 minutes later, car wouldn't crank. Husband jump started & it's cranked and drove fine for 2 days. This morning, car just clicked when I turned the key. I was told by a friend that also has a bmw that it was because I hit the power button on my radio & that's what has shut my car down because she had the same thing happen to her a couple years ago. Have you ever heard of this? I'm having a new battery put in tonight but if the problem is with the anti-theft system in the radio button, I'd like to save my money on the new battery.

It's a five year old battery, it's probably toast. The radio has nothing to do with it, there is a "comfort" circuit that allows radio operation, it might be at fault. Start with the battery, let me know.
