What can cause the center display that normally says mazda RX-8 on it, the time & outside temp. and stuff to malfunction and blink extremely fast? Recently, I started up my 8 and all the indicators on the display were immediately flashing. It's really distracting and I can't read anything. Does anyone know how to go about fixing this? I checked all the fuses in both locations and all were fine. The flashing went on for 2-3 days. Today when I started the car, it had suddenly gone back to normal. I'm worried it will do it again anytime now. I'd also like to mention that I have an aftermarket head unit installed. Is the wiring for the display that's flashing be close enough to the wires/cables for the head unit? If this happens again, I'm wondering if I'll have to take it to a mazda dealer.

your headunit faceplate is not plugged all the way in or has gone bad. its not actually the LCD
the wiring for whatever kit you have (metra, corksport, whatever) has to be plugged in firmly or it will cause the LCD to go crazy
This is correct, it happened to mine. The faceplate is attached to the stereo with four screws, and two of the female ends had cracked. I removed them and glued the cracks, problem solved! This maybe too late but oh well
If you have a Metra kit, the display flashing can be fixed by a firmware upgrade to the kit. Go back to whoever installed the radio, and ask them to use their USB bootloader cable to upgrade to revision 1.4.
