Does your correct speed match what's displayed on the screen? Try reseting the 3d calibration screen & you might even wanna try to do a master factory reset. Once you do that on the 3d screen there are 4 units, display, left turn, right turn, and 3d these bars might have to be fully charged before its calibrated 100%

I had to connect the vehicle speed sensor wire the the correct location. The best place to find this wire is to take the speedometer panel out. When you connect it, reset the 3D calibration screen. When you drive, your actual speed speed should match the speed on the screen. A couple soucres gave me the wrong color wire, so make sure you don't get the wrong info.

I also have the X930BT. I was having the same problem. The location of my vehicle was different from what showed on the GPS reciever. I changed to main GPS unit and also the antenna, but the problem still existed. The real problem is the vehicle speed sensor. If you go to the 3D calibration screen the MPH should to the same speed as your car is going.

When the vehicle is stopped go the the 3D Calibration screen. While you are parked reset the speed pulse feature. Then start driving and it should be ok.
