Why not get your source signal from the turn signal switch on the steering column? That won't "blink" and won't have the problem of getting confused if you have your hazards on.
I was just thinking about that. i will most likely connect it to that. On a side note, a user emailed me a device that is made to do just what i want to do with the FB. It connects 3 sources, so what i would do is connect the DQP to the rear source, that would show me all 3 screens. Then I connect left and right to the device. When i use my blinker it switches to left or right. Thing is, it is $51.00, but because its in Canada, i also have to pay $19.00 for shipping and $27.00 for a costums tax.
