Hi,
I have a X5 (2005) and I live in Belgium.
Since I have installed v28 (and now also v29) from v25 I have the problem that the expected arrival time (ETA) is not correct after I entered the destination. After I start driving and hit the motorway time is getting more acurate. But I a go on the B road it get wrong again.
I seems that the ETA is calculated upon the current speed and not upon maximum speeds on the various roads of the journey.
I never had this with version v25.
I found some topics in the forum about this issue and everytime the solution should be recoding by the dealer. Is this really the answer. What do the nav software have to do with the car. It knows the distance and it knows the speed I can drive on the various roads. So why can it not calculate it correctly and what is recoded in the car. Can it be done with the NavCoder software I found on this website.
Can I ask my dealer to recode even if they did not install the new version?
Thanks
