Compass is absolutely crazy, even after calibration.

So I have a brand new 2011 Wrangler Unlimited 4 door, assembled in Egypt.

To give you an idea of how bad it is. If the compass is showing North (Shows north when its not north) and I make a left turn it now shows NE and then East.

I have checked with a Garmin 550T and a handheld compass.

I have calibrated the compass 5-6 times, 2 of them in the middle of the flat desert where I could not see anything but sand.
Even tried disconnecting the battery for 5 min and recalibrating.

I live in Cairo, Egypt and per the manual I should be in VAR 8 and it is.

I made sure my cell phone and all other electronic devices were off.

Any ideas? Can the dealer order an new compass module?

Brand new JKU, why sweat it? Take it back to the dealer and let them worry about trying to figure it out. The compass module might be installed incorrectly, but you've got a warranty. Hopefully that's the only thing that's screwed up.

Did you reset the magnetic zone number? I had a magnetic map in the disc that came with mine (made in the US) and the setting needed changing to the correct zone. The magnetic map may be way different for Egyptian builds. However it does seem odd that east is "left". Perhaps a sensor may be upside down.

Yes if Magnetic Zone # = Variance. Mine did not come with any disc. I don't have a NAV screen. Just UConnect.

Yeah, the variance is the zone control, but that wont make eastward to the left, I'm pretty sure. I can look up the zone for your area once I get back in (couple hours or so) if you don't know if that is right. Or someone may be able to dig that up quicker. I bet the compass sensor is upside down. Warranty.

Mine doesn't have nav on it either, but the variance setting is in the reset area of the steering wheel select user settings area where the compass recalibrate option is (not by holding the buttons ect. like the manual said for mine).

Settings area? Is this area accessed though the radio. I have done everything though the reset button on the left side if the steering wheel.

I bet they installed the module upside down. It's only held on by 2 screws. On the bottom of the dash cover. This thread will show you how to remove the cover and compass.

Good luck

Nope, took the whole upper dash out. No compass or any other module.

Interesting. My manual claims "
Magnetic materials should be kept away from the top of the center of the instrument panel. This is where the compass sensor is located.
"
I doubt you have a magnet up there, but maybe the module has moved from the earlier location to over the instruments somewhere.

Maybe wave a magnet around, carefully, and when the compass moves you are getting close to it.

Yea, probably a good idea to move it from under a storage bin... Now to find where!

I tried sliding around a small rare earth magnet over the whole dash area but couldn't budge the compass reading. I'll try again later with the reading real close to where it changes over and a bigger magnet to see if that works better because now I'm curious as to where it is located.

Thx. Maybe around the sound bar...?

Visited once, but my comment was directed towards the handful of fine Americans who have reinstalled their compass module backwards/upside down. They know who they are.....

Chances are the compass was preset in America, that would be the reason why east Is pointing "left" in America all compasses point to the north pole and if I'm not mistaken (I'm good at physics not geography) Egypt is below the equator which means all compasses above the equator will have east pointing "left" when below.

Mind you. This can be changed using an electromagnet to reconfigure the poles

To completely clarify- above equator the north pole is where the pointy red thing on a compass faces

Below the equator the pointy red thing points towards the south pole screw navigation lol

I believe driving around in a Bermuda Triangle type of environment can also play havoc with the compass. Have you awoken in the Jeep at all recently, with some new tyres, a lift, and no memory of it happening? Seen any unusual flying objects?

All compasses work the same way everywhere in the world* in that they point North. If you are facing north west is always to the left and east is always to the right.

Egypt is north of the equator and like I mentioned being north or south of the equator makes no difference to a compass

*a compass does not work if you are standing at the north pole.

Being told by Jeep Egypt that it's a problem on all 2011's. Said it was a calibration issue and that the USA has not figured it out... I have a feeling USA '11 work fine...?

Mine works fine. If all the compasses in North American 2011s worked backwards you bet they would have found a fix for it.

I was really hoping that you had a solution by now. Have you actually located the module? Or checked to see if all (OK, a few other) Euro versions are as messed up as they claimed?

Best of luck with this.

Heh Heh, this is funny-

Hell I didn't know if we were at the North pole or South Pole, stupid compass wouldn't work-

Yea, they said it was the USA engineering team who had not figured out how to calibrate the compass.

We found the location... its a bit more involved so I have not taken that area apart. http://www.wranglerforum.com/f33/whe...ted-91876.html

They did show me another 2011 that was showing the same heading as mine...

It did seem like a lot of work to dig that module out, when it is really a warranty item anyways. When they finally get it sorted out, please drop a line. I would like to know what the ultimate problem was.

If all the 2011 Jeeps have backwards compasses over there... expen$ive for Chrysler. I wonder if it is cheaper for them to stick in the NAV unit rather than rip the dash all apart to flip the compass modules over, en masse.

I wonder if the connector can be installed backwards. Most of the time that is not possible, but it may have the same general effect as flipping the module upside down (inverted signal). Can you see the compass module wire if you pop off the tray above the radio?
