Instruction sheet could be better.
2004 Toyota Matrix
Crutchfield Customer Review (What's this?)
Worked well-once I figured it out-but be careful which tabs you cut off. Drawings and instructions are not that great. Some tabs were shown to remain but had to be cut off anyway in order for factory bezel to be reinstalled. (toyota matrix).
Pros: Worked fine once the proper tabs were cut off.
Cons: Better photos in the instructions would be better
