Finally got the reverse alarm! - Click HERE for Original Thread

DaleB
yes, Post 1700 to tell you I finally got my reverse alarm from Trilogix of Canada.. through the 12voltshop.com

Here's pic of all the components and I will foto the install. It should go on quite easy. It's been on sale for $99 reg. $149.
Only has 2 sensors. I plan to mount them above the plastic fake skid plate thingy on the rear bumper. Right on the ends of it. The fake skid doofus pulls away a bit from the plastic bumper covering just enough to hide the wires in there, then under hitch and the up through the same grommet as the hitch wiring. I can put the small module in the storage area.
The sensors plug into the control module and 2 wires to ground and pick up the 12 volts from the left side back up bulb wire.
The display and tiny alarm wire to the drivers fuse box and ground. The little display mounts up by the rear view mirrior and recieives the signals from the module through wireless means.
We shall see how it goes, watch this space!

Here's the kit, arrow pointing to the antenna for the display

DaleB ... Cool, thanks for sharing ...

Is the display battery operated [self-contained] or does it wire to vehicle 12v system. If it wires to vehicle system, why did they bother to make the display [receiver] wireless if you gotta run wires to it anyway?
frostyra
DaleB -- I second that notion! Does it give a visual distance display AND an audible tone? And what led you to choose this unit over, say, the Poron?

frostyra:
Availability and price. The only advantage (at this point) of the Poron are 3 sensors.
They would seem to operate similarly.

srbep:
The only reason for wires on the display unit are for power. Of course for control you would have to run much longer wires.

Yes, it gives you a tone as well as a display of distance.

What?! No sexy voice to warn you of impending doom? What a rip off. :D

I do have Navi, maybe the 'union' only allows one voice-over per car.
srpbep
Or maybe a voice would have forced renaming of the vehicle from MDX to MDXX:

Picture the following scenario as you proceed to back up and there is indeed a wall [or other obstacle a distance behind you]:

OK [when putting it in gear].
More.
More.
....
More.
Slow down.
Getting closer.
Go slower.
Almost there.
Stop.
Please Stop.
Dang it, stop.
...
...

Am I banned? :17:

Hi. I was wondering if anyone has considered purchasing the pilot reverse camera for the mdx. I would think that since they are basically the same acr that it should work well?

Just curious. I am thinking of doing something like that.

What "union" doesn't understand won't hurt her. Unlike some of us who installed the Poron system with the voice, I guess you are not able to experience "menage-a-trois" with your navi girl and your back-up girl :D.

Shh... Don't tell my wife. She thinks I installed the back-up alarm to make it easier for her to park ;).

emperorish,

Here is just one of the previous threads discussing this topic:

If you do a search, you will find out that there are several others addressing this subject. Search function is your friend, use it wisely :).

Ok, I've installed the heart of the unit, the sensors and control module. I will do the display another time when it cools down out there. 90 + in the shade!
It actually works just fine without the display unit. I have the control module mounted in the storage area and the beeping is piercing enough to hear even when close to the car from the outside.
I put it in reverse, it beeps once initially, assuming nothing is directly behind me, it is now quiet. I start moving back and the beeps get more frequent, until it is a steady tone about 18" from the object.
It detected a tall object on either side, or in the center, it starts beeping about 5 feet away. It detected a wash bucket on the ground, at about 3 feet away.
I have the hitch bumper installed, and not sure if that might have some effect on the the it's range or coverage error. But overall, I would say it's very effective.

Sensors wires run between fake skid plate and bumper cover.. forced apart with a thin blade wrapped in cloth. Then clean off zaino finish with isopropyl alcohol to mount sensors.
DaleB
mounted. Keep sensors wires well inside bumper cover for protection from exhaust etc. ...
DaleB
wiring is relatively easy once you get it up inside the grommet on the drivers side and inside the rear storage area.
I cut split to let the two thin wires up inside. Sealed the slit later with RTV. The big black pipe like object is part of the hitch.
DaleB
now up inside the storage area, same much the same story with regard to this grommet.

DaleB
more detail. I had already mounted the module on the outside of the plastic covers which lines the storage box at the rear. The Green with Black Stripe (ignore silver paint marks) is the reverse light connection. The only black wire is ground.
Makes no difference if you have a hitch wired in or not, this all done on the car side of the trailer connections.
DaleB
Wires spliced in with squeeze connectors, final step before putting plastic cover back on in storage area and trying it out.
DaleB
The module inside the storage comparment.... there are other places it could easily be installed with either 3M tape or velcro.
DaleB
I was having a problem with this reverse-aid system. It beeped too much as if it was too sensitive.
It turns out after finally getting a response from the 12voltshop.com that the sensors needed to be realigned.
I did not pay attention to the slight curvature of the rear bumper of the MDX causing the sensor to react to objects on the side like posts, fences, etc.
Also, I was told that aiming it higher will make them less sensitive to the ground. I did both so they were aimed straight back and slightly up.
Now it works perfectly. It begins to beep about 5 feet from an object and within every foot of closing in, the beeps become faster. About a foot away it becomes a solid tone. It becomes a solid tone before object hits my hitch-step.
I have not yet installed the front display which give you the closing distance. I have the module installed in the storarge area (pic) and it can be heard clearly.
Success! Highly recommended, and now on sale for only $90.

Displays in feet or meters. With or without beeper. Also a strobbing LED shows which sensor (L or R) the object is closest to.
It is wireless except for power of course.
cardingtr
just curious.
Where are you going to place your radar detector?
DaleB
It fits fine in usual place which is just below the tint! I will show a pic with them both in place later...getting crowded around there!
TheWorm
Good pics, Dale. I like that blinking LED feature to indicate which sensor is picking up the obstacle. The Poron doesn't do that.

(cardingtr - I mounted my 8500 right where Dale has mounted his reverse display; it fits, and still works fine through the tint, but it precludes using the sunvisor. It's become my nighttime stealth location; daytime is behind the mirror, to the right a bit).

I looked at the 12v.com site and they also list two "wired" sensors. Did anyone look at them? Seems the wireless has some wires anyhow, why not go with the other cheaper system? Thanks for any input, and Dale, thanks for the great pics of the install!:)

that's where exactly where I put my detector too.

When my windshield was replaced yesterday:( , I prewired the the roof where it meets the windshield just in case I jump on reverse aid.

I wonder can you put 2 displays? One beside your rear view mirror and another on the rear glass? So when you back up on tight spots like parallel parking, you can look at "rear display" while looking through the rear glass.
DaleB
There are reverse aids that mount in the top corner of your rear window. Red, Yellow, Green lights and a beeper. So you can see them in the rear view mirror or when you turn around.
It only has once sensor though. But you never know, it might work ok, for $50.

I got the one sensor reverse aid from 12voltshop.com for my VW Jetta. It works really well. The one sensor pretty much limits it to only small vehicles. It is relatively easy to install. The reverse aid mounts right to the rear window, the lights are alittle bit difficult to see during daytime, but the beeper is loud enough. Well worth it for $50.00.

Q: How did you realign or aim the sensors? Did you use some sort of shim?
DaleB
Exactly. I used sections of velcro strips (of all things) and stuffed them in the lower opposite corners of each sensors.
Sensors attach with the usual 'remove cover and stick 'em' adhesive.
With a sharp blade (the edge AWAY from the bumper cover) I slowly peeled them off the bumper enough to insert shim.
Then sealed all around each sensor with a small bead of RTV.

12Voltshop sells some very inexpensive electronics. Time will tell how well everything holds up over the long haul.
But definitely useful devices.

Thanks for the reply. Just out of curiousity, what is "RTV"?

Clear or blue silicone caulking. (Room Temperature Vulcanizing).

Very nice system Dale. Like the pictures with the posts, good job!

Do a search, there a thread on it. I ordered it from GoRhino. They offered a 10% discount at the time.
But the exhaust will eventually melt the right side plastic end cap. I devised some caps out of stainless measuring cups. Looking for permanent ones....but they see to work fine for now.
Very handy accessory overall.

DaleB,

I just installed the same backup alarm as you did -- thanks very much for your pictures; it helped me out a lot. (It sure was tough to find a good power source behind the dash, though. I finally did find power and ground and ended up mounting the display in front of the gear shift, just below the "change" holder. I didn't want to attempt routing the wire behind the headliner and the A pillar.)

The display seems to work fine once the sensors have something to zero in on. However, if there's nothing behind me, the display seems to flash random numbers every few seconds. I was wondering if that's what yours does, or is it because I haven't put in any shims in the sensors?

Also, it would be nice to be able to turn off the beeping from the control module -- I did turn off the beeping from the display unit. (Or did I miss something?)

First of all, I don't think there is any way to turn off the beeping from the control module, without actually going back there (you have it in the headset storage area?) and disconnecting the tiny power plug.

Yes, I had the random beeping before aiming the sensors more parallel across the bumper. The bumper has enough curvature to aim them towards outside areas and trigger off of objects further to the side of the car.
I also aimed them up ever so slightly from parallel with the ground.
The system will randomally beep if you have an angled driveway, so when backing they sensors are aimed at the road. Same thing happens if the rear wheels dip into a rain gutter while you are backing. That's perfectly normal. Just imagine a light beam emanating from the sensors in a shallow cone.
As the car tilts, the road will be detected as the sensors are aimed downward. Once you have it set up right, you can test it by parallel parking and watch and listen to it respond as you back towards the car behind you.

A quick update on my one sensor back up kit from 12volt. It is still going strong, however you do have to clean the sensor pretty constantly during the winter as it tend to detect everything. When it rains, the sensor goes off if water drips on to it, and in the snow, the dust/salt also tends to set it off. I had to wipe it down quite alot this winter. The Poron actually works very well, not really any false readings, just when I back out of the driveway due to the angle of the garage. IMO, the 12 volt is good but you get what you pay for, it is only like $50.00. The Poron is alot better but you also pay for it, double the price of the 12volt.
