Check your wheel pulses - are they working? this is most likely the problem.
Observe them in the GPS service mode. Wheel pulses should be positive and increase with speed when going forwards, negative when backwards.
Check the direction of travel, Backwards when in reverse, forwards in all other gears.
Make sure gyro sites at approx 2500mV, going up to 3000 when turning right, down to 2000 when going left.

what option is the wheel pules ?? or where can find it

Nav service menu: Press Set, then press and hold MENU and wait.

After 10s display will switch to service mode
Observe wheel pulses in Sensor check (car must be moving!)

I go under Sensor check thats all I see
Wheel Sensors
GPS Satellties
GPS Status
Gyro
Directions

I don't see a wheel pulse ??

Wheel sensor = wheel pulse. Same thing.

Make sure it works - increases as speed increases, shows negative when going backwards

when I watched it, its said 1, it never change, car moving or not

KiwiJochen, thank for all your help, I took car to the dealer on Monday, showed them that I am not getting any reading off the wheel sensor or the pulse, they found the wire between the GPS unit in the trunk and sensor was bad, changed it, now its all working good

Thank you again
