i just got a 2004 maxima se. i wanna know the best way to use my phone or wire an aux to the head unit. i have an aftermarket stereo, but i don’t want to take the stock one out bc of all the features it offers. also the climate control shows on that screen so idk if i would even be able to change it. Any ideas?

 

Bluetooth fm transmitter? that's what I did for now
