HUD > HK > rest
Leather dash, u do not need over the rest.
DHP, could be useful, but HUD or HK beats for more usefulness for me.
Side and top cameras, you do not need for parking.
Just get the round blindspot mirrors and stick them on your side mirrors. When you have to parallel park, it will show you where your rear tire is exactly, and will show you like 2 to 3 lanes around you. Blindspot mirrors and a rear view camera will be enough for any parking situations. Less than $10, you will see a huge difference. Trust me, I laughed at those mirrors until I tried them myself.
Just choose the HUD
