Installation and Setup
The setup is easy to do by plugin in the transmitter into a cigarette lighter socket.
Set the car radio to a open FM frequency with no station on it. Here it is set to 88.1.
The FM transmitter is set to the same frequency the radio is on. In this example 88.1.
Go into a smartphones Bluetooth settings and look for the HK106.
Touching it will Pair the smartphone to the HK106 allowing all calls and music from the phone to play over the cars speakers.
This includes music from online sources or stored on the phone.
The built-in microphone on the HK106 picks up your voice when talking on the phone and the call carries on over the vehicles speakers.
Summary
The HK106 Bluetooth FM Transmitter is a good unit to use and play music, or make calls from a smartphone over a vehicles stereo.
The built-in microphone works very good at picking up voice calls.
Play back of music over a car or trucks speakers is also very good but will of course depend on the speaker system.
How good music sounds over the stereo will always depend on the stereo system installed.
Overall the HK106 is a good low cost unit that does what it was built to do.
