Tips:
1.Why car radio doesn't turn on, or car radio doesn't turn on after using for a while ?
1.1 Make sure the Red cable is with ignition positive, Yellow cable with Battery Positive (12V +), Black cable with Battery Negative (12V -). Please use the Radio in 12V output vehicle. We do not recommend you using voltage adapter to power up the radio.
1.2 If the radio is still off after you confirm all the wires are wired correctly, please try to joint the yellow and red cable together and wire it with the 12V positive.
1.3 After the two steps, if the radio is still not on, please check if the fuse is burned or not.
2.Why car radio can turn on, but the radio is no sound, or sound disappear after you play the radio for a while.(it can play USB Flash or SD card, just no sound) ?
Notice: There are two main reason that would cause 'no sound'
A.Speraker negative cable is grounded.
B.The amplifer chip is burned when the item is shorted in wiring.
2.1 Please check if your speaker cable is shorted or not, please make sure every one of them is isolated wired.
2.2 If you confirm that the wire is correctly wired, you can find a speaker elsewhere to do an extra test, which could easily confirm the problem is from the radio or your car's system.
3.Why car radio's Bluetooth is not working, or it work for a while then disconnect itself ?
3.1 Try to 'forget' the device first, and then search for Bluetooth signal again, you may need to input the PIN code which should be "0000".
3.2 If the last step can't make the Bluetooth back, try to find the 'reset hole' on the front panel and do the reset for a try. If it's convenient enough, you can also try to unhook the power connector behind for a few minutes and replug it in later.
4.Why car radio's mic is not working, phone call from the other side can't hear clearly ?
4.1 Try to check if the bluetooth volume setting.
4.2 Try to check if the dashboard is too low (the mic is too far for you) for the radio's MIC to collect your voice.
5.Why car radio cannot read your USB flash disk or SD/TF card ?
Please confirm what's the capacity of the USB flash disk or SD memory card. It can read lower than 32GB disk normally. Please use the other flash disks with fewer songs to test again. (Please confirm if you insert the SD/TF card in a correct side).
6.Why car radio's remote control doesn't work ?
Please check if the remote have the correct battery inside, the correct model is CR2025 model.
7.Why car radio has noise problem ?
7.1 For some cars, there might be some noise generated in the playing. Especially when you are using amplifier. Usually, this kind of problem is related with interference. Please make sure all the cables are wrapped well in case of any contact with each other.
7.2 You can find a speaker elsewhere to do an extra test, which could easily confirm the problem is from the radio or you car's system.
8.Why car radio cannot save the time or radio station setting
Check if the Yellow cable is wired with your car's battery 12V + (constant positive) or not, it provide constant power to the unit and save the setting.
