When I bought my SRX the radio worked like every other car I have owned. If the radio was powered "on" when you turned the car off then it would come back "on" when you started the car an hour or so later (after the car had powered down). In the last couple of weeks I have to push the power button to turn the radio "on" every time I start the car (after the car has powered down). I have had it into the dealer 3 times and they say that is the way it is supposed to work but I am skeptical. It didn't use to work that way nor has any other car I am aware of work that way. Has anyone else experienced this problem or is it just me. They recently did a software update which they said would fix the issues with the radio but nothing has changed.
