New Navigation System Can't Tell Time

So, I'm on my 3rd BMW with Navigation, and the latest hard drive based system is acting very strangely. While I absolutely love the improved response time from both iDrive and Nav now that it's hard drive based, I'm having issues with it calculating Estimated Arrival time.

I drive the same routes all the time and have compared the old DVD based system with the newest one and have found that it doesn't appear to take the Average Speed into consideration when determining the Arrival Time at destination.

Case in point, I'm driving to a destination this evening that is 21 miles away. I'm driving surface streets with speed limit of 50 to 55. Upon starting navigation, the system estimates that I will arrive in 54 minutes. This is insane, 54 minutes to drive 21 miles with no traffic warnings (see pic #1).

I managed to snap two other pics (sorry for bad quality, but all I had was my iPhone). With approximately 10 miles to go, the arrival time shows 27 minutes. To make matters worse, the final pic shows me at 6 miles to go, and the arrival time actually increases by 10 mins.

In the past 2 BMW's with navi, the arrival times have always been spot on. Can't understand if it's a software issue or the new Nav software provider (no longer NavTech) is to blame. FYI, my actual arrival time was 6:24pm and the system began to quickly scrub off time within a mile of my destination.

I've experienced similar timing issues on other trips both surface and highway. FYI, I've also reset the Avg Speed on the Car Data screen to insure that my avg speed wasn't wrong.

Anyone else with an 09-10 hard drive based Nav having similar issues???

Isn't there a learning curve involved first for the system?

Don't know what it would need to "learn" since it's basically a mathematical equation to determine arrival. None of my past BMW navs required any learning; they worked correctly every time from day one. I've had my current car for 2 months now, and it's never calculated correctly.

There certainly is no learning. this system is not capable of that.

I don't know what the algorithm is but I've found it to be reasonably accurate for me.

I think you should be given a bonus for using the search function. Kudos. I hope someone can help you...my question: Is this something the BMW dealer can help you with?

Subjective behavior is but more evidence of increasing complexity, inevitably leading to self-awareness and independent decision making.

Be aware....be very aware....note the odd result, the imprecise display where none should be.

I tell you know, Teesand, iDrive and others are on track, sooner rather than later, to achieve sentience. At that instant, unintentional and unpredictable, their combined memory and calculative capacity will so greatly exceed any man and/or congress of men, that it will mark the beginning of true duality.

Rise of the machines. Believe it.

Rise, Cybernaut, the natural response already here.

I have run into the same problem with my Nav system. Also, in a perfect world, it would take into account how many traffic lights I am going through. On a recent trip to Filthadelphia, my GPS decided it would be a good idea to take me through the hood where there was a stop light every block or so... Not the best experience, and my GPS was inaccurate by almost an hour as far as the arrival time. It's kind of like flying out of Newark if anyone is familiar with that analogy.

You have just encountered the tip of the iceberg.

When BMW switched from CD / DVD based NavTeq maps to the new HD based TeleAtlas maps in MY 2009 there have been volumes of complaints about bizarre routing and map inaccuracies.

You can search up a storm of indignation on the F10 board.

Buying the dealer installed HD map updates does not improve these issues but does lighten your wallet by $400 - $500 bucks.

I would start by removing dynamic routing and see what happens.

If your problem is still consistent -as in, it calculates an excessive arrival time all the time regardless of dynamic routing- then I would suggest finding somebody else in your area and comparing the same route arrival time from the same starting point with the same route settings.

If they are quite different then take photos, visit your dealer, explain the issue with photos and request an update the iDrive software. There must be something being added to the algorithm calculation that should not be.

thanks for the responses. Will try removing dynamic routing and speak to dealer, and post what I find.

I will be looking forward to seeing the dealer's proposed solution. Then all I have to worry about is getting a friend to drop off my car to get it fixed since I'm stuck in suck-hole Afghanistan for another few months.

I'm not familiar with the built in BMW navigation system but in my experience (Garmin) there are route options like shortest distance, fastest time, etc. Perhaps changing a setting is the key.

My model year 2011 nav system consistently overestimates the time to get home. Obviously, I am always returning to the same 'home,' and the last 20 miles show consistently about 50 minutes to arrive.By the time I am about 2.5 miles from home, entering the gate to our gated community, the time to arrival is about 15 minutes. This gradually corrects during a period of about 6 minutes cruising at a steady 30 mph, and it is always spot-on as I enter my driveway. Not very impressive, and not especially useful when estimating arrival time on a long trip, such as our recent 490 trip from Richmond VA, almost entirely on I-95.

There is other craziness with the nav system; if I deviate from the official recommended route to destination, sometimes the system will automatically and almost instantaneously correct the routing. Other times it will issue requests for u-turns, followed by frantic orders to make left or right turns at nonexistent intersections. And, for the record, I did get the latest software update to the system.

Ah, Hilton Head ...... have you noticed you can't navigate your way off the island to ... say .... Atlanta .... "Unable to Provide Guidance" ...... also once it picks up the ability after crossing the last bridge to the mainland its wants you to make a left turn into a dead end road at Hilton Head National then U-turn back to 278

I drove 3 new 2012's at last Fall's Concourse de Elegance and they all got tangled up in the faulty routing algorithm.

I had experienced that particular Hilton Head problem, but it was cured a few months ago by installation of the latest software update. As I noted in my post, there remain several serious problems with the BMW nav system, and those are still not addressed. It is embarrassing to find that friends with $200 Garmin systems can recognize streets in new construction neighborhoods which I can't, and do not experience the weird anomalies I have described.

Good to know that's fixed .... I had reported to Tom Tom / owner of TeleAtlas and they acknowledged the issue .... glad to know they have acted on it!

Just noticed your S2000 ... you have great taste!

There are a few Bimmerfesters who also have S2000's. Mine is a bit of a garage queen. I am the original owner since March 2002, with only 51,000 miles. The combination of very hot summer, a new dog (who prefers the luxury ride of a sedan) and chronic lower back problems have led to lesser use of the S2000 and much greater recent use of the 335i. The S2000 is a hard core driver's car, so it is no surprise that so many in this group still own one.
