Strange thing happened to me yesterday. I went for a complete tire change (summer to winter tires) on my 1 week old E60 525dA. I re-initialized the RPA after the job (as explained in the manual). A few hours later I noticed that the arrow on the NAV PRO map was moving backwards in stead of forward and therefore showing a complete wrong vehicle location. Forward left turns were indicated by the arrow moving backwards and right and vice versa.

My guess it had to do with the changing of the tires. I stopped the car and re-initialized the RPA. From then onwards the problem was solved. This morning everything still ok.

Does anyone know whether the RPA initialization is linked with the NAV sensors or is my NAV on the edge of breakdown?

I seem to remember reading somewhere (in the manual or maybe the Nav DVD booklet) that the Nav uses the ABS wheel sensors to help with Navigation. These sensors are also used for the RPA. So somehow they are linked.

 

Maybe they put the right-side tires on the left and the left-side tires on the right? That would confuse the sensors wouldn't it?...












Just kidding...

 

Park the car safely. Lock it. Hitch a ride home and mail me the title and keys and location. Do not hesitate. Do it at NOW!

 

My guess would be the nav map was set to point north and your wer going south.

 

Are you driving in reverse?

 

No. Arow was pointing up but whole pointer (arrow in circle) was moving down while map was facing direction of travel. It was really going the opposite direction of travel, not sticking to any roads anymore.
