Unlike other units that transmit with FM, the Ugreen plugs straight into a 3.5mm audio jack and then pairs with a smartphone.
This is a good option when there are many radio stations in an area which sometimes can cause interference.
Interference happens more for those who are traveling, and a radio station comes on over the open one set to an FM unit.
A new empty frequency can easily be found, but the Ugreen stops this by plugging straight into a 3.5mm Aux audio line-in.
Not all radios have a 3.5mm line-in, so be sure yours does, or one of the standard options above would be better.
It has a built-in mic for hands-free calling and a built-in battery that lasts 4 hours. A micro USB charger can be left plugged in if longer playtime is needed.
If your car stereo needs a Bluetooth upgrade, there are many low-cost kits to make it ready.
Having a car radio able to answer calls and play music from your smart devices is a nice option to have.
When looking for a unit, be sure to note where the cigarette lighter is located in your vehicle to get a good fit for the unit.
Some cigarette lighter locations can be located in a way that some will not plug incorrectly or be hard to get to.
Units with a long cable to plug in and then be placed in a good spot would be better for such vehicles.
Can these Bluetooth transmitters be used in a with 15-18 yr OEM radio with no Bluetooth capability (only AM, FM, CD & Cassette Tape). I recognize music transfer would be via unused FM channel and in my case, a USB flash drive? Is music quality good using this approach (don’t have smartphone)?
