From empeg's page, the sleeve (the part that is actually mounted in the car, the unit itself is removable for downloading data to it) is 2" (50mm) high x 7.2" (183mm) wide x 6.8" (173mm) deep. According to them, this is the "standard" European DIN size. I am not sure yet how this compares to standard sizes, but my guess is that it is more similar to (if not exactly the same as) standard OEM Japanese and some American head units. If that is the case, Crutchfield even sells adapters for the larger dash openings in some Ford, GM, and Chrylser vehicles. Good luck.
