Did you ever find a place to fix your Information Display on your Mazda3? I too have the same problem. My display went out about a month ago and my car is no longer under warranty. After reading all of the other complaints about the same problem, I say it's faulty equipment! Mazda should replace this for free, since it's a very common problem.
This really works...the fuse that controls the Information display power is the one labelled "ROOM" (15Amp). It is located under the hood in the engine fuses.
I didnt even replace mine, I simply scraped off the dirt/rust from the metal portion and reinserted it. If this doesnt work, test the ROOM port with a functional fuse switch (I used the one labelled HORN, 15amp). If it works with the switch, you have a good part, but need a new fuse.
Free solution to an expensive problem...if you dont know whats wrong.
This is my step by step guide for fixing this problem.
Remove The room fuse.
Carefully spray WD40 into the sockets of the removed fuse.
leave it for 10 minutes.
start the car with the fuse removed.and then stop
Clean the fuse pins well with WD40 and ensure the colour is correct, or insert a new 15amp fuse.
place the fuse back in the socket
it will work then
I ended up getting the part off of ebay and replacing it myself. $29 + shipping as opposed to the almost $300 the Mazda dealer wanted to charge. Replacement was simple and took all of 5 minutes and 2 screws.
If you can find the part, contact me back and I'll make sure you have good directions to replace it.
I wound up taking it to the dealer. They removed the display and re-inserted it, said the problem was a bad connection, and sent me on my way. I'm still a little leery, but it's been working fine since, and that's been almost two months so far. Hopefully, the problem won't resurface, but if it does, I'll definitely try the fuse trick first. Thanks!

I researched and finally found a fix for non functioning Driver Information Center.
The solution was similar to that found for similar modules on other brands of vehicles.
Remove the Driver Information Center Module
(See GM manual for procedure)
Push back clips from black housing box and carefully remove circuit board
Place circuit card flat on table.
Place display and component side of circuit board facing up
Rotate circuit board so the display module side is facing you
There are button switches on either side of the display module
Look at the right button switch.
Next to it just left and above are four 1/4" X 1/8" black components attached to the circuit board
They are marked 430, 430, 820 and 820 reading from top to bottom.
These are resistors with 43 and 82 ohm values.
On the two modules I have repaired the problem was with the top most
resistor. It is marked 430 and is 1/2" above and 1/4" to the left of
the right button switch. The soldering to the circuit board had
fractured. I resoldered the resistor into place using a bit of solder
and 15 Watt pencil soldering iron.
The problem is NOT the black spot on the display in the upper left corner
The problem is NOT the DC to DC converter modules.
I disconected the negative battery cabke and keft it off for about one hour. When it was reconnected the display retruned to normal except the temperature now reads in C instead of F. I don't know if the time it is disconnected has any inopact, but doining this essentially resets the display. Goof luck!
A re-furb radio will be provided at no charge by Honda Just give them your old one and some figure under $100 which is ridiculous for a burned out light bulb. People have had far more success doing more damage by trying on there own. Sorry for the bad news. I would strongly suggest going aftermarket. Everything you want probubly @ kijiji
Start by removing the colored strip which is over the radio display. (best way is to open the glove box and get underneither it, the right end kind of hooks in at an angle while the left end locks in straight. so work your way to the left first and then the right)
once that is removed, you shuold see four (4) standard screws, remove and save them. You must remove the top air vent piece, just tip up and pull forward gently. You will have to disconnect the hazard switch plug also
the stereo set can now be removed by pulling forward gently. Only two cables are connected to the unit, one can be pulled out, the other must be unclipped.
At this point the WHOLE UNIT including DISPLAY should come out of the console.
On mine, there were directions on how to install and uninstall the CD/MP3 player and if you flip it over you can see where the MINIDisc would go (if you don't have one)
