Triangle indicating my position doesn't move & not properly located on map. HELP!
 

I have an MKII.

I just updated my software to the most current version relevant to my unit. Worked fine.

My PDOP is <5. I have several satellites with S/N higher than 10. I am receiving 8 satellites.

Dead-reckoning signalling is working properly. Gyro is workin properly.

I compared my location coordinates with my friend's portable GPS and the system has me in the correct spot.

BUT..............

The triangle indicating my position does not move at all when I drive. It spins, but it does not move forward.

I am not placed properly on the map. Sometimes I am 5 miles away...sometimes elsewhere, although I am always in my city. I have owned the car since fall. It has had plenty of driving time to "find itself." Actually, I do have proof that the GPS knows my correct coordinates, so I can't explain this at all.

I can manually place myself on the map using the system's function for that. However, I am then "stuck" wherever I placed my position. I don't move; only rotate.

OCCASIONALLY (maybe every several weeks t best) the map randomly updates to my current, correct location. However, at no point does the triangle move with my car. It always stays static.

HELP!!!!!!!!!!!!!!!!

As per my other discussions with you, the issue is the wheel pulse signal is not present, therefore the Mk2 does not update its position
