Report "I just uninstalled the stock radio installed a Sony CDX-gt640 into my 2004 Toyota Camry. I followed all the steps and reviewed all steps. The problem is that none of the operation buttons work. The deck lights up and goes straight into demo mode. The only thing that really works is my iphone when I plug it in. It wont even eject or play the cd I put in. The remote doesn't work either. I have reset it several times...Help!!"
