Car Bluetooth Receiver LBT-990 Aux Jack Repair

My car is a 2010 SM3 and doesn't have a built-in car Bluetooth function.

So I was using a Bluetooth receiver LBT-990, but the AUX jack broke.

I was thinking of buying a new one, but then I thought, why not solder it directly to an old noise filter I had?

So I jumped right into it hahaha

First, I disassembled the noise filter. I placed a flathead screwdriver on the side of the noise filter and hit it with a hammer, and it came apart easily.

Looking at the AUX jack on the noise filter, I saw that there were five soldered areas.

To see what they corresponded to, I removed the top plastic part and examined where each part touched the AUX cable.

After confirming each part as shown in the pictures above, I stripped the LBT-990 wire and soldered it to the corresponding locations.

I closed the lid of the noise filter and connected it, and it worked well.

With that, the LBT-990 AUX jack repair is done....

After installing it in the car, the cable length is shorter and it looks neater.

The sound quality isn't great due to my phone's own quality issues, but the sensitivity is much better than before.

I can't wait to get a better car. I need to make more money.
