In the US version in '06 Mazda separated the wiring harness for the LCD so that you could remove the HU but keep the LCD functions.
Pre '06 in the US several people extended the wiring harness for the HU and relocated it somewhere else. The glove compt. and the trunk were the two places I heard of people putting them.
