Information Display Problem
 

Started to notice in May 2010 that the information display on my 2006 RX8 started to have an intermittent problem where the display would go from a normal state (see fig 1) to a solid bar state (see Fig 2)
The dealer has already dinged me for $400.00 by replacing the display but I still have the problem. Tried working the connection with no luck.
Next step I'm told is replacing the audio unit.
Anyone have a better soluation?
