I have a 2004 Honda Civic (5 speed). My brother (who is not an auto mechanic in any way) installed this stereo back in May. It stopped working in July randomly. Won't turn on, won't do anything. I've changed the fuse already, reset the head unit as well. Best Buy says it may just be a loose connection- but they won't touch it since they didn't install it. The stereo is an Alpine CDE-102.
Anyone have a similar experience, or clues at to what may be wrong. I am mildly capable of small repairs.
Thanks in advance.
