I don't have one but I looked at it after seeing an ad.
Looking at the specs:
Compact Size - just 4.8"W x 1.5"H x 1"D
It should be able to fit in a 1 DIN spot
I wasn't too happy with the OBD connector setup because my connector is in the driver's footwell along the right shin. The plug and cable would be rubbing on my leg while I drove unless I decided to relocate the whole plug.
