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 Peter Bates

I've been using a Bluetooth hands-free car kit for a long time, now it needs constant charging. Instead of going down the reload route this time, I decided to try one of these things. So far it's been great, I plug it into my 3 port cigarette lighter extender and it sits right above my phone which is horizontal in the holder. . Not only do I use it to make and take calls, I can now stream Spotify/SiriusXM (saves me having to pay a monthly fee for another SiriusXM device) and other music from my phone to my car speakers. I use a direct connection to my AUX port for the best sound quality. Calls to my end sound great and the person on the other end says the sound is pretty good, maybe better than my old device. large and easy to press accidentally. The I/O port is quirky too. Since it offers both input and output, if you're using it to output audio to your car's AUX port when it's on, the connection should be there. It then recognizes it as an exit port. However, if it is connected AFTER the device is already powered on, the port thinks the connection is for INPUT and not for output. Time. Powered by car. Cons: The buttons are actually too big and easily accidentally pressed. An unusual I/O port provides an unusual AUX connection (must be connected at power-up). I wish there was a way to turn off the voice of the guy saying "waiting for mating" and just beep.
