I put one of these on just after I got my 2007, though I only used two of the 4 sensors since that covered the rear well enough. I don't have a full writeup or pics, though it's not too difficult of a job.
Power was run from the center console cigarette plug - which turns on / off with the ignition. I added a switch here so I could turn it off if I wanted to, otherwise being on all the time hasn't caused any issues as opposed to having it powered from the backup lights.
The display I mounted next to the drivers seat, in the little space between the center console and the seat. There's enough room to see the display if I want to, but otherwise it's out of the way.
There's a control module that I mounted underneath the rear passenger seat.
The sensors are mounted on small plastic brackets I made from an old plastic tool case - attached to two screws just above the licence plate and aimed outward from center to get good rear coverage.
Have to pull out the trunk liner / trim to get the wiring installed. Otherwise it's under the carpet and such - there's holes with rubber plugs in the rear to get wiring in / out of the car, just search for where is the best place.
And make sure the wire length is enough to get to the sensor / control module / display before you start.

Thanks for your reply.

Is there any disadvantage with 4 sensors installed, instead of 2?

I will try this soon with my new mazda 3 but i wonder if that will void my electrical system warranty of the car?

Anyway, i will try to post some pics if i can.

No disadvantage of 4 sensors, though depending where you locate them on the bumper, there may be foam directly behind it, which will make wiring a bit more difficult.
I originally chose two since it covered the area, less obvious of an install, and I wanted to put the other two on the front of the car too. Though the wiring isn't long enough to reach both ends of the vehicle, and splicing the wire adds enough mismatch to look like the sensor is near a wall, so that the sensor for that channel beeps all the time.

There is no electrical concern, you're plugging into the 12V accessory outlet... with a 12V accessory = no problems.

Hi,

I want to install front parking censors to my Mazda 3. Can ayone suggest where can I get them and how much would it cost.

Is it advisable at the first place?

Thanks
