I have an alpine CVA 1005 Mobile Media that does the following, not necessarily all at once or even on the same occasions. 1. Unit will not come on at all
2. Unit will come on, but no image on display. No sound or control.
3. Unit will not be on, then all of a sudden will come on and work normally.
4. Unit will come on with Noice only on speakers until you hit the change radio station, then it works correctly.
