Chosen Solution

How can I add AUX connection to my corolla, and listen to music from my phone?

I found a better solution, with this two simple steps:

  1. I got this 20$ aux adapter off ebay.
  2. installed it like this youtube video. and it works! the volume is a bit lower than the radio but the sound quality is great.

Hey Chen! What year Corolla do you have? To my knowledge, all Corollas after 2009 have AUX inputs. If your Corolla doesn’t have one, the easiest way to add one would be to install a stereo that has a AUX input.

I would like to suggest another solution. Try an FM transmitter. https://www.amazon.com/Nulaxy-Wireless-B… Connect to the above device using your phone’s bluetooth. The above device should then be set to an FM radio station where there is no music normally on the radio. Tune the radio to this channel, and you will be able to hear music wirelessly.

An fm transmitter with bluetooth would be nice but sometimes you hear static or popping sounds.
