HMC5883L Digital Compass Installed In Upper Console

I installed the HMC5883L Digital Compass into the Upper Console, I struggled long and hard for s good starting place to install this very tiny sensitive device. You are supposed to keep them away from wires and metal, lol well good luck with that as where in a car can you install something like this that it's not going to be fairly close to some sort of metal or electrical wires. I thought about somewhere in the dash but again same problem plus that area is close to the Engine Bay so I figured "Nay Nay" on that idea.
The trunk area I thought but then I'm running an excessive amount of wires for a 5V tiny device. The Upper Console seemed like a good idea as it's only got the T-Bar metal to deal with, it's somewhat centrally located, and yes there are wires but how close is "Too Close" ?? I guess when I take the Upper Console out for a test fit I'll find out won't I? If that does not work then I am at somewhat of a loss as to where a good place to install the compass would be. At least in the Upper Console I can run the 5V Power and ground off of the same one that the Temperature Sensor Module and Compass Indicator LEDs are using. Anyways, I hooked it all up to my Arduino Mega & Unity 3D setup and gave it all a bench test and it seems fine with the exception of the Compass still needing to be calibrated properly, but it all works. That Temperature Sensor I'm very impressed with, that thing works beautifully.
