I am hoping someone can help me. Last week I bought a T300 to replace my T500. So the problem is this, while driving in a straight line I can feel my car moving side to side and I can see it also in the replay. It's making me absolutely crazy and causing me to make driving mistakes. Also I feel some slight vibrations that I know shouldn't be there. I really miss my T500 it worked perfectly for 70,000 miles. I never plugged my T 300 into a PC, could that be it? I would really appreciate any help thanks in advance.
