so i am trying to install a aux port to my car radio. Its a RBK version 2 radio and has an microelectronics ST TDA7536 amplifier chip. I have tried to go through different routes of adding an aux... trough the radio hardness (too low of volume coming from a phone) & thorugh the am/fm tuner (could not get to work). So i decided to go directly through the amplifier chip. I found a pinout of the chip and when by that for what i would solder to. de-soldered pins 12 and 13 from the board & soldered them together with left audio input from the cable. de-soldered pins 15 and 16 from the board & soldered the pins together with the right audio input from the cable. Attached ground to the board ground. All the other pins remain attached to the board. I though i would be able to just plug a 3.5mm jack into my phone from the cable, turn the unit on, press play, and start listening. But unfortunately it doesn't work, its wired though... i touch the tip of the jack and the left speakers get static, touch the middle portion of the jack and the right side gets static. Just looking for help to get it working and see what i did wrong.
I know the radio will not work now and the aux would be the only means of playing music.
