Here is one for Pioneer Radios but should work for other brands, except Alpine. AM and FM reception is decent, but probably because I live in Hawaii radio reception is bad to begin with haha. And lastly, I did not see a separate power wire for the antenna, unless it is aftermarket.

ok, I went on Amazon and found the 1400NEX you mentioned and found a backup camera that looks like it will work fairly well. There were a couple of other items recommended - one to control the radio from the steering wheel and the other I'm still not clear on - looks like it might be used to be able to play videos without the car being in park. If that's the case, I'm not interested in that as I don't want distractions for my 16yo daughter nor do I think she'd honestly want it. If that cable does something else that actually makes it useful, please let me know.

Parts I'm considering: stereo unit - https://www.amazon.com/gp/product/B07951J34N/ref=ox_sc_act_title_2?smid=ATVPDKIKX0DER&psc=1

backup camera - https://www.amazon.com/gp/product/B005Q65ZIK/ref=ox_sc_act_title_1?smid=A2KV19AYUKS3X0&psc=1

steering wheel controls - https://www.amazon.com/gp/product/B00B4PJC9K/ref=ox_sc_act_title_4?smid=ATVPDKIKX0DER&psc=1

cable of unknown usage (lol) - https://www.amazon.com/gp/product/B00A9AQPUU/ref=ox_sc_act_title_3?smid=A1AUFI5NHGNZ61&psc=1

All for under $365 seems very fair to me. Am I forgetting anything else?
