Hello Harry,
The escutcheon plate is in three peices. Each piece has one m5 stud on the back which is fastened through ther dash by 10mm nuts. Access these throug the radio opening and the glove box opening. I use the box end of a very short 10mm wrench. Move the heater controls all the way inward to access the outside 10mm fasteners and all the way inward to access the inside 10mm nut.
During re-assembly do not overtighten the nuts or the soft metal studs will break off!
