So, I think Ive narrowed down my nav accuracy problems to something with the learning status. Whenever I reset the learning status, the nav accuracy is perfect. After the system becomes initialized, it starts getting worse and worse. Usually after a few days, I need to reset the status again.

My question is how can I shut off the learning status? It seems to me the system works better when the learning status is at 0.

Thanks.

Do you always have a strong GPS signal? Do you drive in an area where the sats are blocked by buildings, mountains, trees, underground parking? If no then maybe your D3 is not working correctly. I don't think there is a way to turn the learning off.

Do you have your VSS hooked up to the correct wire?
