Navigation Calibration and Adjustment
 

I recently upgraded to Nav OS v26. On the old OS, if I held down the INFO button a screen would appear with a selection for NAV or RDS. In the NAV submenu I could adjust the GPS positioning in increments (+1, -2, etc.). Has this feature been moved or removed? Is it obsolete?

No on knows? Not even UCrew?

That is not GPS calibration, it's navigation volume minimum adjustment. Have you also lost Select-button functions? Maybe you should try these instructions: http://www.xoutpost.com/articles/x5/n...s-upgrade.html

TP volume stands for Traffic Patrol Volume. Since this feature is a radio volume INPUT control that uses the same inputs as NAV, it actually increase the nav audio volume. To set the advanced features including TP volume see this post http://www.bimmerboard.com/forums/posts/154948

No Calibration is needed in the X5. The X5 never came with MKI (to my knowledge) which had a "calibration" feature.

Navigation Calibration is detailed in this document from BMW, page 35

Okay, so perhaps I am describing this wrong. I did the base calibration of entering an intersection and then pressing "crossing intersection". The system will accurately plot my location until I make even a subtle turn (especially traffic circles). The unit does not accurately track these turns (yaw) and will drift to parallel streets if they are within a block or two of my actual location.

So I was wondering is there a way to re-calibrate or diagnose the gyro and/or wheel sensors (though the give a reading in the service menu).

Thank in advance,

You can see if the sensors are functioning by entering the Navigation Service Mode http://www.bimmernav.com/advanced.htm
Sensors are located under Sensor Check
