DLO TransDock III (with IntelliTune)

The DLO TransDock III offers better-than-average FM transmission; it offers auxiliary line-in and audiovisual-out ports and includes an adjustable arm mount. It also has four preset slots.

The DLO TransDock III is somewhat bulky, and it can be tricky to set it up out of the way of various in-auto controls. The IntelliTune feature doesn't work.

Although the DLO TransDock III FM transmitter works OK in urban areas, it's a better choice for drivers who frequent areas with a less cluttered FM frequency range.
