You mean like this highly accurate sensor?

I have one of those in the garage , looking for something a bit more geeky !

Friend did on their car because the wife wouldnt reverse to within half a meter of anything. Problem was they were in OMG panic mode at half a meter so just reinforced her belief that she was about to hit whatever was behind the car. Camera was a much better solution for them, but the first numberplate mount one couldnt aim down enough to actually see the gap.

Place old motherboards/phones on garage floor. When you hear the crunch, stop.   ;)

Probably find most car radio installers would be able to do them - try Jonvy on the Shore (just around corner from PBTech, so go shopping while waiting ;) ), they were well priced and fast doing our radio install.

Yes I have reverse sensors which I fitted myself.  There was really nothing to it, and it has made a huge difference to my confidence when parking. I paid about $100 from Supercheap for mine, but they don't appear to hold it any more.  The kit comes with four sensors, a junction box that the sensors plug into, and a display unit. Oh, and a hole cutter for the sensors as shown in this image. Similar kits sell for a song on TradeMe (I can't bring myself to mention the price, because I'll start crying )

I had to pull up the carpets to run the cables, and take the center dash unit out of my Pajero to find some power.  This is my installation (I used to work as a commercial photographer, and try to do a half decent job even with pictures like this).  It took me a couple of hours to fit all told.

When reversing it starts to beep when an object is within 1.5M, and the beeps get faster as the distance decreases until the distance reads zero, and the beep becomes a continuous tone.  There is about 125mm to 150mm between the tow bar and object behind me when the display reads zero.  I always used to be convinced I was about to hit the vehicle behind me, and get out and have more than a metre, so I love having this kit installed.

A bonus is that my kit has a GPS speed readout which is way easier to read than the car's speedometer, and it tallies exactly with my TomTom and dashcam (you can never have too many gadgets), so I use the reverse readout and dashcam as my default speed displays.

Problems — there's usually at least one — the reverse sensors don't work when they get wet.  Nothing electrical.  They just don't like having water droplets on them.

The tiny CB is a GME TX3100.  It was not too expensive, easy(ish) to fit because of it's size, and does all you need of a CB. 

@TLD Did you hardwire in the power for your CB radio?

No, it shares an ignition on feed with the car radio, but I think it would take a very long time to drain a truck battery in receive only mode.

I've installed a couple of the TradeMe kits - not that difficult for a DIY person. At least one is still going strong 4 years later and working well.

Ideally, get one with sensors the correct colour, or you will need to paint them too.

I have this which is brilliant.

I installed first product on 2 our cars 6 years ago. best $50 spend on car :) I connected power wire to reverse lights, so sensor is working only when reversing. I had zero DIY car skills at that time and it took me about 2 hrs to complete the job per car.

Could you buy two and wire so works for front and back?

I see no reason why not, but you'll need dedicated power point for head unit, otherwise no point to switch it when reversing and detecting front collision.

That's an interesting idea, and as per the previous answer, there's no reason why not.  You'd have to sort out the power issue, and there'd be no reason to wire them to the reverse lights if you went that way.  You'd need to switch the power manually so front and rear sensors would be active at the same time.  The wires between the sensors and junction box would need to be extended for either the front or back sensors, and you'd have to decide where to place the rear sensors (you wouldn't be able to place them on the corners).

kryptonjohn: Are there airbag sensors in bumpers to be aware of when drilling and fitting these parking sensors?

Are the sensors one event?  Do they latch on when triggered?  I mean if you disconnect the battery ground lead so that the bag couldn't go off, even if you managed to trigger the sensor by forgetting to take your power drill off its hammer setting, would the bag(s) inflate (explode) the moment you reconnected the battery?  It feels unlikely to me, but definitely worth looking into.

Here you go.  This makes it look like the sensor will go straight back to its normally-off state right after whatever event caused it to trigger.
