My display on my stock Monsoon Stereo for my 2005 Bonneville GXP has gone out. At certain light I can still see that the display works it just does not light up. Is there a company that can fix this or I can buy a new one. I've gone to a dealership and they told me it would cost $500+ just to fix it. I'm now trying to sell the car and this is not helping the sell.
