The FM Transmitter has an overall great functionality

It turns out that it also has really well designed handsfree / speaker phone functionality for calls while you're driving, plus you can plug in any audio source with a phono

Pros - The unit looks very nice, has a good, clear display, it's very easy to operate, the Bluetooth pairing process is simple and works as it should, dual USB chargers with a smart chip, multiple input options using auxiliary plug, USB flash drive, micro SD card slot or Bluetooth
