On most car models, to switch between built-in CD changer and YT-BTA, you only need to press CD source button for once or twice, same as original car stereo operation. 2. On some car models YT-BTA is with MP3/CDC switch cable, when needing to use original CD changer, you just have to switch to CDC end;Conversely, switch to MP3 end to play YT-BTA. Such switching is advised to be operated when car stereo is turned off or the car is turned off. Some car models may require turning off and restarting car stereo for once after switching so that it can work normally. 3. On some car models with pre-installed CD changer, you need to disconnect original CD changer to install YT-BTA. 4. Yatour YT-BTA Bluetooth car adapter operations, such as Track up/down, Disc+/Disc-,Fast/Reverse forward are almost equal to operations of original built-in CD changer or external CD changer. Some buttons of some car stereos may be changed, but such changes will not affects functions of original built-in CD changer and external CD changer. Functions not mentioned in original car stereo manual can not be achieved on YT-BTA either. There may be a little difference on functions of different car models and different car stereo brands. 5. On some car stereos, too frequently pressing buttons during operation may cause track info displays incorrectly or playback stuck. And you can turn off car stereo and restart it.
5- Common Troubleshooting. 1. YT-BTA doesn't work after installation. Please check whether the wire harness is correctly connected. And if there is GND wire(for some car models), please check whether it connects well with metal parts of car radio. 2.Frequently switching or other unknown reasons cause playback stuck. Music playback is from function of mobile phone, you just need to start the playback from mobile phone menu. 3.External audio input(AUX IN) sounds too low or too much noise. Adjust volume of earphone output of your external audio device; It is not proper for external audio devices to use car power, because common ground noise will occur in this case. External audio device should use its own battery to play. 4. Why I can still hear the former mobile phone Bluetooth A2DP music when I plug in AUX device? When AUX IN function is used, you need to press CD2 button or Disc+ button so as to switch YT-BTA to AUX input mode, then AUX input audio can be played. 5. My car has a CD changer already, and can I still add an YT-BTA? For some cars models equipped with existing CD Changer, we can offer Parallel Harness, which allows YT-BTA to hook up with the existing CD Changer. On Some car models you only need to press CD switching buttons once or twice so as to switch between the two devices. But on some other car models you need MP3/CDC switch to change between them. However, please note Parallel Harness is not available for all cars. 6.YT-BTA is universal for all kinds of car models? No, since all kinds of car brands have different CD changer port types, YT-BTA have different connectors for different car brands; the hardware and software of YT-BTA are different too.
