Audio AUX in the stock Chinese radio (Geely Panda, Panda cross, Micro Panda)
I have Micro Panda 1000CC car. I has a simple Chinese USB and DC capable audio player, but it haven’t any auxiliary connection. Because of the i cant plug my phone and play songs from my car audio player.
If I want to play music on my car by plugin my phone, I have two choices,
- Replace new auxiliary supported audio player.
- Open the current player and try to inject auxiliary feature to the current player.
At this movement i haven’t enough money to place new player to my car. Then i go trough with the second choice and i success with it.
Now I’m happy to share with this solution with everyone around the world.
Please follow the step i deciding on below.
This is the car audio player on my car. you can follow this step if your car have exact same player. (Do it at your own risk)
Pull out your out player from the dashboard. It so easy by using flat screw driver. When you remove the round shape plastic cover from the dashboard you have the access to the player 4 screws. remove the screws and simply pull out the player(Unplug the power connectors and the speaker connectors).
After separating player from dashboard unscrew the top steel panel of the player. When you remove the top plate of the player you can see this circuit board.
Remove the ribbon cable on the circuit board. There are two cables are attached to the board. After that you can closely look at the amplifier chip on the left side of the circuit board. its crewed to the player casing. Unscrew the chip screws.
Unscrew all the screw of the board and pull out the board. After getting board to your hand check the chip call TDA7388. Her is the data sheet of the chip tda7388. In data sheet of the chip they tell we can giv direct audio feed back to the pin number 11,12,14,15 pins.
I soldered four wires to above pins of the chip. I soldered two brown wire to the pin 11, 12 and tow blue wires to the pin 14,15. I’m going to twist same color wires together and giving audio signal to them.
In data sheet they added 0.1uf capacitors between the input wires and the chip. Also i added the capacitors to the wires.
another side of the capacitor going to aux cable input wires. In above picture the gray color wire is aux cable. Finally we need to ground the aux cable ground wire. I found some good ground place in the circuit board and i solder the ground wire to it (See below picture, that blue color jumper wire goes to ground).
Now you all done. Solder 3.5mm jack to other end of the aux cable. Reattach the circuit board to the player (Don’t forget plug ribbon cable and re screw the TDA chip to the casing). Install the player to the car and test new aux feature of the player(Switch to the USB Play mode ).
The biggest problem if this hack is when we play aux, track on the usb drive is playing. I found a fix for this, we can put empty tack to the usb and let it to play.
