So i have a 2007 Infinity G35x that I bought years ago. It has a salvage title because the previous owner had some water damage. The FM and AM radio has not worked for years, so I would just plug in my phone in my AUX attachment in the center console, everything was great. Last month I got a new radio from a newer 2011 infinity G37x, the FM radio works amazing, but the AUX does not work at all. When I press the Radio or Settings button, there is a little beep that confirms I pressed the button, but when I press the AUX button, It does not beep and does not work. I plug my phone into my aux cable and nothing happens.
*side note - my G35x did not come equipped with a backup camera, but the car I got the radio system from did, so when I put it in reverse, I get a screen with backup camera lines, but it is just black... lol.
Any suggestions for how to fix this?
