HUD OBD 2 Advice

Unless your needle is way off, the same information is being sent to both the onboard speedometer and the information pulled from the ODB port. So I'm not sure how you are getting GPS speed if your speed sensor is way off.

Although, torque does have the option to display GPS speed intead of reading the ODB port

With my GPS showing 60 km/h, the spedometer shows 65 and the OBd port shows 60-61.

It all depends on how the speed signals are decoded, how the speedometer is driven, and how well it has been calibrated When it was made.
