I purchased a soundstream SNX-731 flip down radio from you guys a few years back. I installed it in my project car that I was building, my projects all done now and all of a sudden the radio comes on and shows the main screen but wont load any further I reset the radio and it still does the same thing, I know Ive had the radio for a while but it havent been used much at all what could the problem be? And I think this radio has been discontinued Ive been trying to buy another on but cant find them anywhere.
