i installed an aftermakret headunit in my '95 900se got the harness adapter for the radio, and bypassed the stock amp for the door speakers. the radio all works fine and sounds great. but now my sid only displays the outside temperature, sometimes it will flash a whole bunch of horizontal dashes for a split second, and when i switch to see what my fuel mileage, DTE or anything else is it appears as if i just cleared everything. and sometimes the backlight on the small analog clock does not come on. is this because i removed the stock radio? or might i have loosened some connection on the back of the sid?
