One of the pet peeves about my car has been the fact that ever since it was new, my XM radio (plugged into the cigarette lighter) would shut off when I restarted my car after a short stop. It would stay on while the car was shut down and the key removed, but the power to the lighter would be shut off, just for a moment, during cranking. I always assumed that the system shut off power to everything except the starter while cranking. Good idea, but it was a pain to have to turn the radio back on, wait for it to aquire the sat signals again, etc.
My car had been cranking slowly in the morning for about 3 weeks, and a couple of weeks ago, it cranked slowly while warmed up. That got me to take it down to the dealer to get a new battery. $150 later (installed), I drove out with my new battery.
Ever since then, I've noticed that the XM radio stays on during cranking. I love it, but I'm also wondering what caused the change. It's always shut off, even when new. Any ideas?
