I'm looking at purchasing an Oxygen Audio O'Car head unit:
http://www.oxygenaudio.com/o-series/363-o-car.html
And received the following advice from the sales lady:
O’Car is a slightly larger single DIN unit that most car stereos, so please read the attached manual with product dimensions and installation requirements to make sure it will fit your vehicle before purchasing.
It will not fit in most Japanese cars.
(I've uploaded the manual here if anyone is interested: http://www.padgett.com.au/files/OCAR%20MANUAL.pdf)
Will this fit in a '90 NA6?
