1. The product only operates on a vehicle with 12 Volt DC negative ground
system. Do not use it on other voltage system.
2. This product only fits OEM or aftermarket car stereo with CD changer port,
and different solutions of Bluetooth adapter would be adopted according to
different brands of vehicles or different car radios.
3. Make sure car stereo is powered off before installation, otherwise the car
stereo may be damaged. It is suggested to install it at car dealer shop or
professional car stereo store.
4. Usually, the car stereo needs to be removed so as to plug BTK’s main

installed in glove box or trunk where external CD changer port is located
(Requires special splitter cable).
Working Modes Instruction
After finishing installation of BTK, press once or twice the CD (or Disc /
Mode / CDC / SOURCE / AUX etc.) button to switch to CD changer working
mode (BTK mode).
Yatour BTK offers 2 types of working modes: HFP/A2DP mode, AUX IN
mode.
Under BTK Bluetooth HFP/A2DP working modes, the car stereo should
be under CD1 mode, and you should see CD 1-1 on you car stereo.
When you disconnect current bluetooth connection from your mobile
phone and BTK will switch to AUX IN mode, BTK’s AUX input will be valid.
1. BTK 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 you need AUX IN function, you have to disconnect current
bluetooth connection from your mobile phone and BTK will switch to AUX input mode status .
