You see, I'm not sure that the motor is to blame.
It seems to me that if the problem is of an electro-mechanical nature, its behavior ought to be constant, doing the same thing every time the system starts. My unit is operating normally with frequent use of the car. Once I leave it alone for a couple of days, there it goes again....

I'm also planning on reflashing the unit. Also looking at moding the V32 image with night mode :-)

I'm positive we'll find the solution soon...
