Everyone knows by now that the Atrix mounts do not work with most cases, especially with the Otterbox Defender case since it is rather large. In my quest for a car windshield mount I happened to come across an extra mount for my garmin Nuvi GPS that I had sitting around. After checking out the size I realized it could easily be modified to be used with the Atrix Otterbox Defender case. What you need: Motorola Atrix Otterbox Defender Case Garmin Nuvi windshield mount (ebay - Do a search for Garmin nuvi mount, they are very cheap, get the one that looks like the one in the photo) Thin Foam padding (I used some I had left over from an Air conditioner installation) Scissors Dremel & #420 Cutoff wheel All you need to do is trim the bottom and top tabs for the Garmin mount with your dremel cutoff wheel. While I didn't do the cleanest job, I'm sure you can make it look nicer if you care to. Use the plastic indentations on the Defender case to determine how much to cut off of the Garmin mount. You will want to start your cuts to the left side of the original Garmin tab, The reason for this is that you want the phone to sit the furthest to the right hand side as you can get it, so that the flap for the usb power cord plugin can open without hitting anything. By starting to the left side you will have ample room. After you do the cuts if you test fit your phone in the modified cradle you will notice that there is a bit of side to side play, and if you shake the crap out of it the phone will fall off of the mount. To remedy this situation and put tension onto the new mounts I used my scissors and cut (2) very thin pieces of sticky-backed foam. I had some sitting around from a air conditioner installation, but you should be able to get it anywhere those types of things are sold. Stick them onto the backing as in the photo above and you are done. That's it. You now have a nice cheap dock for your Otterbox Defender-equipped Atrix. Enjoy.
