I bought my 500bt a few months ago and it was working great. About a month ago it stopped recognizing my ipod, but i didnt use it that much so it wasnt a big deal.. But now i went to upgrade the firmware. It went through the transferring files screen, then the screen went black and will not turn back on. I tried the reset button and everything i read about on here. Pioneer was no help since my warranty was up. The screen is black, but when i first turn on my car the bluetooth light comes on, but turns off shortly after. If anyone can help me or give me any ideas it would be greatly appreciated. Thank you
