AUDIO OUTPUT METHOD
There are 3 audio output methods:
Built-in speaker
When playing music with a USB flash drive,
the sound comes out from the built-in
speaker on the back.
AUX line transmission
The AUX line is transmitted to the original car
player. Not all vehicles have a 3.5mm (AUX)
input (AUX Cable not included).
FM signal transmission
1. Six preset FM transmission frequencies, and then use the original car radio to search for
the transmission frequency.
2. Manually set the FM transmission frequency:
3. Adjust the original car radio to an empty channel position, such as: “92.3MHz” (to avoid
conflicts with local radio, interference signals).
4. Set the FM transmission frequency to be consistent with the frequency of the original car,
such as: “92.3MHz”.
5. At this time, the sound is transmitted to the original car speaker.
