So are these "parking sensors" only in the back? or do they do the front bumper too? Please advise.

Thanks

I already have an after market kit that i bought before my ride, but the this is that with after market, i have to put that thing on the top of the dash :S

The back, plus the front outside edges of the front bumpers... so no sensor directly in front of the vehicle.

Can this option be added after purchase through an OEM kit?

I've always thought the 2 fronts in the corner were for the dynamic cruise.

No, radar cruise (a massively more expensive option than park assist) uses a different front emblem (the actual lexus emblem on the front is different)

Parking sensors are good idea but not worth it. Rode in a friends car who has it. Beeps every time a motorcycles pass by, annoying as hell. If you can drive, you should be able to park without depending on technology.

I've NEVER had it beep while driving, even in bumper to bumper traffic. Plus, you can turn it off easily, if desired.

Honestly, the only time it beeps "accidentally" is if a passenger walks around the car when they get out. Also, because of the slope of my driveway, it will beep when I reach the edge of the driveway, because it picks up the street)

So what if the front doesn't have a sensor in the center. If you don't know how close you are to something directly in front of you, then you shouldn't be driving.

But, it's EXTREMELY useful for more "questionable" spots such as the far front corner and the entire rear, which is especially great because you can't see the trunk when using the mirror / turning around. Therefore, there is no perception on where the end of the car is. And, this feeling is even worse when you're backing the car up going uphill.

But, keep in mind that I have no nav, therefore no backup cam. I can definitely see the sensors being more needless if you have the backup cam.

Also, I've never had it NOT pick something up. Then again, even if it did, it's a park assist to tell you how close you are to something, not a replacement for observation of hidden items (hence the name)

You are right about not needing to sense the front of the vehicle, not even for the corners. The only way the system would be useful for the front of the car would be if it had a sensor for the front spoiler. The rear is useful if you don't have nav. With the nav I can back up within a 1/4 inch. I have found that the system has a hard time with vertical objects like posts, depending on their location. I found myself almost hitting a couple times if it wasn't for the back-up camera. I don’t feel confident about depending on the PA as the primary way to back up.
