Review on Upgraded Bluetooth FM Transmitter: Sumind Wireless Radio Adapter with 1.7 Inch Display, QC3.0 📻 & Smart 2.4A Dual USB Ports, AUX Input/Output, TF Card Mp3 Player – Hands-Free Car Kit by Brett Martinez

I have to say I am disappointed with the device I received. It looks good, the screen is good and it goes well with my car. The problem I have is that I wanted this to be a bluetooth bridge between my phone and my machine to play music and it doesn't do a very good job. I have to turn the volume on the device all the way up, the volume on the phone all the way up, the volume on the car radio all the way up, and yet the volume is barely audible with street noise. I tried connecting my phone via Bluetooth and an extra cable and the same with both. The radio is tuned to a channel with no station nearby and I have no hiss, just not much sound. Device status messages are loud and clear, almost throwing me out of the car as the stereo was fully on, so I don't know why the music is so low.
