So I just popped in 8.1 nav update dvd and everything works fine just like the old one 4.X. But when I started rolling,the arrow is heading it different directions, not the same as the road I'm going on. Any ideas?

 

Press the N (north) button on the Top Left corner. That will change the mode and show you going the same direction of the street your traveling on. I like it this way also.

 

If you're talking about the view,that's not what I meant. For example, I'm driving down road Lexus street and the arrow+circle thing is not even close to the road I'm on, it'll be like at Acura Avenue or something.I was heading home and it was saying I was driving at the mall.

 

The precision is off. There were a few threads on here about it. Do a search.

 

Cant find any.

 

Go into your settings and calibrate it again. I forgot the exact steps but it should be pretty simple.

 

I think the calibration is inside the hidden menu.

Press Menu > Volume > top left corner (no button) > bottom left corner (no button) > and top left corner (no button)

if you do it correctly u will see another screen.

 

My bad I misunderstood what you posted.

I dont think there is a service menu on the newer disc?
