ok, this one had me stumped for a little while. I needed to remove my head unit (the dreaded ERR3), so I followed Wozza's walkthough. The first step is removing the dash tray, the bit with the central air vents, as shown below (mine is a plain version without Navigator).
ok, so according to the walkthrough you lever off the felt pad in the centre top of the tray, to get at the screws that are holding the tray down. This is the weird bit. After using more and more force to try and get the thing off (which wouldn't budge), I ended up breaking off the felt pad. It turns out that the felt pad was screwed down into the dash tray via screws from the underside (which explains why I couldn't lever it off !), see pics below including the broken bit (which I plan to glue back together).
Also, it turns out that my dash tray isn't held down by screws at all, it just yanks out. So actually there was no need for me to remove the felt pad at all, doh ! But how was I to know this ? Look, no screws !
So, what's going on ? Is this something that is just on early cars ? Mine is a 1999 model Sport.
