Reddit mentions of Zone Tech 4.3 Inch TFT Car Auto LCD Screen Rear Monitor View Rearview DVD AV Mirror

Depends on how skilled you are. I installed a backup camera in mine as it didn’t have the tech package either. It was pretty easy. If you can install a radio you can do this.

I bought this camera Moonet Car CCD Backup Rearview Camera for Nissan-370Z 350-Z Waterproof Night Vision https://www.amazon.com/dp/B00J21TNTW/ref=cm_sw_r_cp_tai_Ln5GAb3WS5H49

and it pops right in with the factory bulb and all

Then a mirror screen like this

All you do is connect the power for the camera and the mirror to one of the positives on the reverse light and you’re good to go. Mine works fantastic. I added a splitter and a 3 position switch so i have a front parking camera too just for fun. But the idea is the same. The backup camera I’d recommend to anyone. It comes with parking lines albeit you gotta get use to them because they don’t necessarily line up with where the car will back up into, but you can get use to the lines as reference points.

As for Nav, i put this in

it’s super easy instructions all you need is a Phillips and a small flathead. I personally prefer my phone for nav because it’s updated, nice, traffic, easier to type and use. Plus i don’t use my phone while driving so it’s either on the mount being used for nav or off and playing music

Then this magnetic phone mount lets you stick and remove your phone from the mount super fast and easy.

I didn’t have much choice for my car to be picky because the 6mt sedans are so rare and this one was $4k and thankfully i was the first person to contact the seller or else i would still be kicking myself. I’m pretty handy and cheap so i add whatever feature i want into my car.
