Head unit issues

[Hholman1999]

So my head unit has been acting up lately. Looked it up many times and found issues similar to mine but not exact so i decided to give this forum a shot. My head unit sometimes doesnt turn on when i turn my car on. It will either come on while im droving or not come on at all. This only happens sometimes though as the deck normally works fine. When the deck does come on it doesnt shut off or anything when i hit a bump or something as other post have stated. Not sure what to do but its getting pretty annoying. Any information helps. I currently have a single din kenwood installed.

Who installed it? It sounds like it wasn't wired to the vehicle correctly.
