Installed my d1 today. When i drive the arrow doesn't go straight, it is always on an angle. Is this just a setting issue or is there something not right. I am reading the manual now, sorry if this is a stupid question.

It's probably just still learning.

sounds like a vss issue. my car has no speed sense wire, so i used an alpine speed pulse generator, where you magnetize the wheel it reads off of. when i rotated my tires and forgot to re-magnetize the wheel, i got the same issue with the arrow

sounds like still learning.

Great. i'll give it some time and see how it goes. The vss is hooked up so i can't see that being the problem.

Thanks All

Nope i am wrong. It is the vss wire. I think anyway. With the VDD on it doesn't show acceleration or speed. Back to check wires.

All fixed up. Thought that the vss wire in my car was behind my old head unit. not the case. Had to use the blue/yellow wire behind the instrument cluster. Oh well. Pretty easy to get at and run a wire.

Thanks again all for the insight.
