No it stays on, just the display flashes. I mean sometimes it turns off but that's only because the locking mechanism for the removable buttons has worn down over the years. But the flashing display is new.
yeah the display turns completely off and the comes back on, but the radio stays on the whole time. and now today when i was driving the radio seemed to freeze. the display wouldn't change when i hit and button including the off switch. i had to pull the number thingy to get it to work right again
