2005 Accord, 4 door, 4 cylinder... I realize the stereo/clock was recalled but I missed the January 2012 deadline (mine just recently stopped working). It worked for a while by simply removing the negative battery cable and then connecting it again. The stereo/clock would come on and work for a short time and then stop again. Now that doesn't even work. The Honda dealer wants $450 just for the <motherboard/circuit board>? not even including labor.I cannot afford this. What are my options? Can I buy an aftermarket stereo and install it or is the problem deeper within?I'm not new to general mechanical repairs but this electronic stuff is over my head. Please help.Many thanks,T
