I'm also now thinking the "Traffic Info" being unchecked wasn't an issue in the first place. I think that just enables the NAV to give me the option to take my eyes off the road and see exactly what roads are having what traffic problems.

Have to agree that paying $50 a year for this level of meh capabilities isn't looking attractive. I presume the NAV will still "work", just w/o the not-so-good traffic aware functionality and w/o updating roads if they're modified.

Ya. I think it will still work. Just no updates or traffic.

BMW nav's biggest plus is its integration with the car. Even with the traffic updates, it's just updating what you already know. ETA increases as you sit in traffic. Waze is good in that you get warnings on cops, and breakdowns ahead. Both try to reroute you in unrealistic ways - like go two blocks up on a parallel street then cut back over.

BMW is worse about doing that than Waze, in general, but I agree - they both could be better about not routing in weird ways. What I'd like is a super quick way to enquire - how much time will it cost to NOT do the right left right again? I suspect that usually it'll just be a minute or less and the algorithm is chattering.

My 2016 M235i with nav + live traffic subscription works great. It's usually correct within a few minutes +/- and always gets me where I need to go. The green/yellow/red traffic overlays are always dead accurate as well.

Only issue is that it ironically cannot locate my local BMW dealer here in Portland. I've mentioned it to the dealer a few times and they just uncomfortably laugh it off because they hear it all the time and have no fix.

I find its biggest glitch is that it doesn't know about time based restrictions on turning.

In Toronto here we have a large number of no left turns during the day and Google maps has no issues plotting a route that avoids these turns during the day and includes them at the appropriate time.

BMW Nav on the other had is constantly trying to get me to turn left during these restricted times.

Anyone else have this issue?

BMW nav is quite poor at ETA even with its real life traffic updates. So google map is far better in this regards.

[MarcoZandrini]

Google maps!

[harma24]

Google Maps:


Or Waze:


I've found in general that Google Maps has better directions and is a bit more conservative with the ETA. However, Waze will often predict traffic which does not exist (i.e., it thinks it will take me over an hour to get to work on holidays such a Columbus Day when half the city has the day off). But, Waze has the three best words I've ever heard from an app: "Police reported ahead!"


Either way, I'm not paying another monthly fee to get something I'm already paying for through my phone! No Nav package here!

I believe apple CarPlay does not currently support waze or google maps. So I did you get those maps on your idrive?

Accurately predicting ETAs would be the next big breakthrough. Granted it's hard. In dense city traffic, all it takes is an accident, or slow motorist to cause a back up. There's no way I can move all the way over from the left to the right to make a turn in the length of a block. On the tollway with 4 lanes, they are all moving different speeds, with a queue at then entrance to the "express" lanes.

Don't hold your breath about accurate predictions of ETA. It was proven years ago that it is mathematically impossible to predict weather. Traffic is a much harder job, because there is even more of a likelihood that a small change (like a serious accident. which is always sudden and unpredictable) will have a large effect.
That said, when in doubt, triangulate: have all traffic apps open at once!

It's not stock; it's an aftermarket Avin display.

? Waze already does a bang-up job of predicting ETA. It's invariably within a couple of minutes, in my experience.

[morphomeman]

I agree that Waze generally gives a reasonably accurate ETA. My response was about the theoretical limit of predictability and prompted in large part by my irritation at people who complain about the inaccuracy of weather forecasting or any forecasting, for that matter.
Some things just can't be predicted with complete accuracy, because of the interaction of highly variable factors. Traffic is one. The stock market is another.
END OF RANT. BACK TO WORK.

I've never compared with Waze but with traffic updates on in the BMW nav, I've found its routes and ETA are comparable to google maps.

My BMW system has always had updates on and is nowhere close to comparable to Waze. Haven't compared to Google.

The stock market is simplicity itself to predict. Anything I buy will go down. Anything I sell will go up. ;-)
