Dear all 3rd gen Vios owners, I've recently purchased a 2014 2nd hand Vios J spec with great deal and wonder if anyone could help me with the following questions,

1. I noticed that the car body is too low and should I change the rim to 16" or use stiffer suspension? I do understand that stiffer suspension might sacrifice comfort but what's the trade off of changing to 16" rim? Or have you guys concluded any best solution for this problem?

2. The car comes with normal audio unit Since my mom and sister will be driving the car, I plan to get them a reverse camera. Should I use the toyota original DVD player with reverse camera or any alternative for that?

Thanks in advance!

The suspension wasn’t modified, but I heard the car bottom will hit the bump when it’s fully loaded.

I don’t quite like the user interface of some cheap dvd in the market, it looks like those interfaces in China phones (if you get what I mean). Any recommendation of a dvd player with simple yet elegant interface design?

Is it with GPS?
