Query: Kensington Digital FM TRansmitter

The unit works fine, but is only useful if your DC power source is a straight shot down, allowing you to read the numbers on the transmitter. On my Explorer, the power source is on the left side of the passenger footwell, meaning that I have to get out of the car, open the passenger door, and crouch down low in order to see the numbers on the transmitter. Without a flexible head on the unit, it is not at all practical for a large number of situations.
