Just want to say thanks …. Had issues with D/Z ICC , "04 XR8 mk2 /Factory Ghia upgrade" the LCD was blinking on n off, which was then making the fan for ac ,unable to use, CD player wouldn't work, got to the point where ive been pricing an update ICC , Then after reading ya thoughts on here, I ran an earth from battery to the earth point on the ICC, "right hand bottom 8 mm bolt that fixes the the unit to the dash. Works like a new one. Put a multi meter on it and the earth was a bit over half a volt out, Configured a new earth to that 8 mm bolt and all is well.
Thanks guys.
