The fm does not work on it
How can I add an aux jack to it?

I see LA3361 - FM multiplex stereo demodulator.
If you look at this datasheet, LA3361 pin 4 and 5 is stereo output.
There is some resistors and capacitors.
You must trace it and find it on motherboard.
Good luck.

thank you for the info
i was messing around with it and found that i could get audio from R32 & R33 on the board
but maybe going thru the IC would be better?
and i also wonder how to disable the radio so there is no static

there is a video on YouTube the guy made it Bluetooth but he doesn't show you how to do anything

Since there is no wiring diagram it is a bit difficult to determine the correct points.
You may need to desolder these resistors 32 and 33 and connect the line input there.
Can you take a picture with the location of these resistors?

I desoldered pins 4&5 on LA3361 and soldered the wires from the audio cable to it. It seems to be working.

Heres how I had it connected before to resistors 32 & 33 not sure if there's much difference but with the two pins on the ic unsoldered there is no static from the radio.

Yes, if there is no noise, this is the right solution.
You can do one more thing - to disconnect pin 1 of LA3361, will stop powering it.
