new yaris owner 2017

[logoris]

Picked up my new 2017 SE few weeks ago.

I am new to the Yaris Chassis, I am quite pleased with it.

Couple things I have been looking to figure out.

1) I did not get the premium audio, but I am wondering if I can add the gps antenna to activate the nav, I don't feel like paying 800cad just to get the nav.

2) Do the same engine mods for the earlier 1nz still work on the 2017 eg 1zz tb, cams, cai, headers.

3) Is the car speed limited to 160kmh? couldn't seem to push it faster.

4) Is the suspension the same so lowering springs and struts

5) Will the previous bumper fit on the newer body I'm not a fan of the giant grill.
