I purchased this Bluetooth transmitter for my neighboor, and it put the biggest smile on his face. I wanted him to have hands free calling, and this worked out perfect. It was simple to install, just plug it in the cigarette lighter, connect to your Bluetooth and bingo your speakers instantly become Bluetooth enabled. There are other features such as internet radio, USB charging capability, USB flash drive, micro SD card, with AUX input. The large screen is also a huge plus! I’m happy with my purchase, and recommend this transmitter.
