i did a search but mostly found people with EU version asking why they dont have VR.
so i no longer get the voice command screen when i push in the knob.
all i had done was change the 3d_max_tiltlevel in pioneer.ini and renamed car_grey.mdl to car.mdl and vice versa (silver arrow)
anyway i did back up my data.zip so i just reverted back to the original and still no voice command when i push in the knob. i have tried waiting a while after startup and i have reset the unit but no luck bringing it back.
does anyone know how i can get this work again (well work is a kind word 
but at least get the prompt to come up)
F700, VR did originally function.
