Well it does have a side port located on the left side, and per HTC's liking for landscape mode , bottom is to the right that would make it perfect for docking and since the kickstand is there it obviously meant to be use side ways so, I would assume any accessory manufacture would see the benefits of making a good car dock for a phone that is ment to dock and has a TOM TOM based GPS software.
IDK just a guess id think they'll be fallin all over themselves to patent something really cool and future proof
