Review on Upgraded Bluetooth Transmitter Function Hands Free by Rubeen Black

I drive 90 minutes to work every day and listen to audio books on my phone to pass the time. My 10 year old didn't have bluetooth and I wanted to turn the volume up on the book so I could hear it through the air conditioner. I simply set up the device by tuning it to an unused frequency on my FM radio. It connects quite well with my Bluetooth cell phone. My only complaint is that the volume on the unit doesn't seem to affect the volume sent to my radio. I can turn the radio volume up to 30 to listen to a book, but later when I switch to a regular radio station, BOOM, my ears hurt because I usually turn the radio volume up to 10 (even with air conditioning). So I find it a minus that the volume of the station is not really transmitted to the radio at this volume and I have to be careful when switching from the station to another radio channel. This is my biggest (and very painful) complaint. Apart from that it works.
