Then mounted it using a ram mount. It's very clean and easy for me to use. The radio is mounted behind the passenger rear seat. I also mounted my Delorme Explorer on the drivers side pillar.

I'm not sure if this helps, but for a size comparison, this is the 400d next to a 5" Garmin Nuvi. Also, for what it's worth, I've had the radio since around September of 2015. I do not use it to anywhere near it's capability, but it has worked very well so far. I really like the built in APRS.
