2015 Nissan Altima Alarm/Remote Start/Stereo Wiring

I have a 2015 Nissan Altima SV with small non touchscreen radio. wiring is currently 3 different white plugs (20-pin, 24-pin, 6-pin), I am trying to upgrade to the OEM navigation unit which only has 2 (20-pin) White plugs. I really need both wiring diagrams for each radio. Thank you

I made a mistake in the original post. Current non touchscreen radio has 3 white plugs, (20-pin, 32-pin, and 8-pin). The navigation radio I am trying to swap to has 2 white plugs (existing 20-pin, and a 24-pin)

This was very helpful yesterday. My brother-in-law wanted me to hook up new speakers and a sub in his 2017 Altima. I had to dope out the head unit because he wanted to maintain functionality with it. It's been a while since I've installed a system, but we got it to work via high/low converter. Problem is, it won't turn off now. I hooked up the remote leads for the amps and line converter to what is labeled as the "pink radio ignition" wire. Can this not be used as a remote turn-on lead? Was I supposed to splice into something else? Any help would be much appreciated.

What equipment is installed, some audio equipment has auto sense which will turn on the amp when there is a signal on the RCA, Make sure you list the converter also.

I don't have the specifics. All I remember is that the sub amp is Fosgate Power, the speaker amp is Alpine, and the converter is off-brand. All of these parts were once in my vehicle and functioned as if they did not have a signal sensor to turn on. Does the pink ignition wire supply a constant 12v charge? I thought about using the "factory amp turn-on (white)" wire, but didn't see one. Maybe I overlooked it, but I guess that would make the most sense to use? Thanks for the reply, btw.
