The original sony xr-7180 radio has died, yellow has voltage, ignition off, red has voltage with ignition on, ground wire-black has ground. The Face stays dead, and the antenna does not operate.
My question is; Is this a din 1 radio?
1984 xjs v12 coupe

 

If I understand, a 1 din or single-din radio is 2" tall and a double is 4", so yes.
