Nav System Time of Arrival Issues

mlmcdougall · 09-23-2011, 05:22 PM

I'm a new X3 owner, and on most every account I love the vehicle. My one frustration is the navigation system's time of arrival -- on a 70 mile drive, it usually builds in an extra 15 - 20 minutes at the very least. Even on short trips of a few miles, the estimated time of arrival is significantly off.

While it's not a significant issue, it is annoying. Has anyone found a way to compensate for this?

mine has been fairly accurate.

I'm with the OP. The system definitely overestimates the trip duration.

Mine is usually bang on. Recent 250 mile drive was only 10 mins out. Guess it's all down to the vector data based on max speed limits on the roads (and whether you exceed those limits). It continously adjusts based on how fast you drive but 20 minutes out for only 70 miles is way off

I think you need to adjust the compensation for the traffic conditions (low/moderate/heavy). Check your manual...

I find it's more a problem with the data.
On my commute there is a section of country road with a 70kph limit it always says I will take 20 minutes to drive 10 km. It's therefore assuming I can't go faster than 30 km per hour for the section.
I haven't tried to narrow it down, but I think there is a section along the route where they have typed in 7 as the limit instead of 70.
That would explain it for me.

Mine has been accurate so far!

Agreed, I'm actually surprised as to how accurate it has been. Usually within a couple minutes for a 30 minute trip.
