Positives:
- It really works as easy as they had hoped. simply set the same frequency the radio and instrument and off you go.
Negatives:
- The quality of the music is good, as long as music is. when it is quieter times in a song or any music comes crack it and there are many interfering frequencies.
- The unit does not save the set frequency, ie every time I climb into the car I have to either adjust the frequency or left at the preset 87.5MHz.
- The USB port does not play music from mobile phones from as it actually does any car stereo with USB port.
Overall, not recommended, and no alternative if you want to save money compared to a car radio with appropriate connectors.
