I found a video on youtube that shows a hard shell case that works with the motorola window mount car dock. The guy said that it works and he does show the case in the mount but the case is not on a phone its just the case because he is using his Droid X to shoot the video. But he does say that it does fit when the cover is on the phone. The case is made by Rocketfish and he says he got it at best buy. I looked it up and best buy has them for about $25. I have'nt bought one yet, I was hoping someone els would and confirm that it works. I have already spent about all the money I want to spend until I know for sure if it works.After paying $40 for the car dock and $25 for the case that wont work with the mount, Im just a little gun-shy about buying another case. If anybody confirms this I sure would like ta know about it. Check out the video on youtube and decide for yourself.
