    1990 Deville w/ "symphony sound" problems

    Hey Guys, I am new to this website and just recieved a 1990 Sedan Deville as a gift. It is in pretty rough shape but I am going to work with it, Right now I am trying to figure out what's up with my stereo. It is the symphone sound head unit, and although there is power to the unit as evident by the clock, none of the buttons or switches will respond. Pressing the power button does nothing, it is just a static display of the clock. If some of the experienced car audio men out there could give me some advice, I would love to upgrade to a cd capable head unit, but there are so many options and I would prefer to not spend a ton of money because my budget is only so high. I have been looking on ebay for replacement systems and I have found a few from newer generation cadillacs but are not sure if they would fit, or have compatible connections. Thanks alot for your help.

    1. it may have a fuse for the radio power try that the radio may run off retained power if that doesn fix it id bet the hu is fried

    2 replacement is probably the best option it will sound alot better the only problem you will hit will be because it is symphony its like bose in that it has an external amp which requires the system to be rewired to the speakers to bypass the amp.

    The problem is with the power switch, I had the same problem with mine and purchased another on e-bay only to have the same thing happen again. It is a common problem with these units, there is a place online that fixes this common problem, but it costs $150.00, not really worth the price
