I have a pioneer AVIC D3 The problem is that the navigation display arrow that shows where you are when you are driving is pointing to different direction. You can change it from the double side arrow that is located on the button corner of the screen to showthe road north every time, but instead of doing that the road are shown diagonally at all the time I would really appreciate if you can helpme to solve that problem

The Gyro in the unit is sticking. The D3 navigation side has not held up as well as the other older systems. It is not worth fixing. The system is considered beyond its life cycle and the death rate of the D3 has advanced rapidly over the past year. If you have monitors and your iPhone and ipad connections along with your siri connected to your D3 then just use it for that. Get a portable GPS unit for navigation or use your phone. The D3 has nice features but navigation is not one of them. Besides the fact that there will probably not be anymore updates for these old DVD driven pioneer units. And the 2012 update was made in 2011 so it is 3 to 4 years old. Sell it quick, before everyone figures out the unit is now ready for the junk yard for GPS units. You might get enough money to pay down the cost of a new updated system that does not use DVDs for navigation.
