Has anyone found a decent case, ideally silicone, that will fit in the motorola car dock? I took a chance with a cheap ebay case and it doesn't fit, even with the insert removed and the nub on the dock filed off. I'd really like to find a case that fits so I can keep it on and use the car dock - is that too much to ask? Searching through the other threads I couldn't find any definitive answers... Thanks in advance!
