Does any one know how often map updates are pushed. I cannot use the navigate on auto pilot feature until the maps are updated. My car is at home and connected to wi-fi,
any info is appreciated.
Help with map updates
No, no one knows how often maps are updated, partly because there’s no notification when it happens. There used to be a notification, and when there was, map updates were very infrequent.
Which firmware version do you have, and which car? Even if your car has access to WiFi, do you know for sure that it’s connecting?
There are two (maybe three) maps in the S/X - Google maps is updated as you see it - so perhaps a few seconds old. The second map is an internal map for navigation (which appears on the left instrument panel when navigating). In the past it has been updated fairly infrequently - perhaps once a year or less. It is believed this map was updated as part of the v9 software release. There may be a third high-definition map used for AP. As this map is not visible to owners, it is not clear how often this is updated or if it is considered part of the displayed internal map.
Compare this with every other automaker. Those maps are between 1-2 years out of date the day you buy the car. Then they charge you $100-200 to get a new map, available once a year. It's often already a year out of date when it is released.
@dlchambers - It may be worth contacting service if it has been more than a few weeks. In rare cases, updates get locked up and service can remotely fix it. No need to go into service.
There is one onboard map - which is used to display the navigation mini-map on the dashboard, and will also be used if navigation routing is performed offline. We don't know how often this map data is updated. For NAV 1.0, the onboard map was updated roughly annually, so this map data could be as much as two years out of date, missing recent construction for new or updated roads/highway ramps.
The visible map on the console is from Google, pulled in real-time from their map server. Google updates the road information almost immediately after road changes have been made (with a day or two). The satellite maps are updated every few months. [We live in an area hit by Hurricane Harvey, within a month of the hurricane, the satellite map was showing the areas underwater - and it took months before the map was updated again to show those areas with dry streets.] The Google map data is only used for display purposes, and is not used for navigation - the navigation route is layered ontop of the Google map.
The third map is stored on Tesla's navigation server. We don't have any details on this map data or how frequently it is updated. This map data is used to perform cloud-based navigation routing, and should be using the highest resolution map data coupled with real-time traffic information to produce an optimum route. The route is then transmitted back to the onboard navigation software, which display the route ontop of the navigation mini-map and console Google map, and uses it for NOAP (Navigate on AutoPilot).
Tesla is building high resolution map data - and it's not yet clear how they are providing that information to the onboard software for use by AutoPilot. It's highly unlikely they are storing the high res map data onboard, due to the data storage/bandwidth requirements.
It would be useful for Tesla to be more transparent about this, provide more information about the map & speed limit data that are being stored onboard, at least so owners could determine how recent this information has been updated.
goodmorning to flags (it's spam).
I would love to be able to flag maps issues, it pronounces names wrong, says turn right when you are clearly merging left on some spots near Austin... there doesnt seems to be a way to provide feedback, and has some crazy ideas on fastest routes that I would love to be able to resolve as well.
Google has none of these issues on my phone, so it's something proprietary to the Tesla maps.
@Monarch: Use the voice command "report bug" as soon as the problem occurs.
TT are you sure the maps update real time on the MCU? Reason I ask, we just had a new toll road open up in Nov 2018. Maps on my google phone show it completed and usable. But on my S, it still shows dirt in places and the road name is missing? I'm eager to see it update do I don't get the re-routing notifications as I drive through open fields!
@EVrider thanks! wasnt aware of that voice function
@N4RCL - I could be wrong. You're talking about the big map on the MCU and not the small map in the instrument cluster (S/X)? The small map can be 6-18 months out of date.
I was about 99% sure the main map is realtime from Google, considering Google is also providing the traffic data. Then again perhaps it is cached at Tesla's server, but seems unlikely.
Definitely not real-time; the big map is also missing a new highway for me and keeps routing me using sub-optimal routes. At least 6 months old.
This can be very confusing, and an area where Tesla should be more transparent in providing status of the various data sources.
The most accurate maps are likely to be the non-satellite street map displayed on the center console, which is likely provided from Google maps data - which is typically updated within a day or two of road changes.
The satellite maps displayed on the center console are also supplied by Google. The satellite images change infrequently on a seemingly random schedule (usually within 3 to 6 months) - so when there are recent road changes, there could be a discrepancy between the Google street map and the Google satellite map.
Tesla distributes map and speed limit data to each vehicle. With the original navigation system, this data was used for routing calculations and for displaying the mini-map on the dashboard. This data was updated roughly every year and tended to be out of date 1-2 years, causing discrepancies between the navigation route and the current roads/speed limits. Plus the speed limit database has numerous errors with missing or incorrect speed limit data.
With the current navigation software, this onboard data is usually not used for calculating routes, and will be used for route calculations only when the internet is not accessible or online routing is disabled. However, the onboard data still appears to be used for TACC to determine the current speed limit - and because the speed limit database is likely out-of-date and has many errors, this is part of the cause for phantom braking while operating under TACC, AutoSteer or NOAP.
Navigation routing is now done with Tesla's cloud server - which should be using more up-to-date maps. The source for the data appears to be OpenStreetMaps (a crowd sourced mapping tool), though I can't recall Tesla making any official statement on their source for onboard and cloud server maps. Their server should be updated more frequently, so it is more likely to adjust to recent road changes.
While we've seen a few issues with routing, especially in areas with current or recent construction, the navigation software usually produces a credible route, better than the original navigation system - and we tend to trust the route being provided (in most cases).
The speed limit database remains a major problem - with incorrect speed limit adjustments by TACC, which can impact safe driving if the vehicle rapidly slows in the middle of high-speed highway traffic, for no reason.
It continues to be confusing that Tesla is using multiple data sources for displaying maps, navigation routing, and controlling vehicle speed. Tesla should include an explanation of this in the vehicle owners guide, so owners can have more confidence about this information that impacts driving.
@dlchambers I had the same problem and started a thread on it, linked below. Bottom line, after wasting a lot of time with Tesla service (multiple phone calls and failed Mobile Service visit), the Navigation Maps Update downloaded on its own when I left my MS in the garage connected to WiFi all weekend from Friday night to Monday morning without touching it. I now have Navigate on Autopilot working!
My car had been connected to WiFi overnight every night for almost a month, and even for 36 hours once with no luck. I've read that the update is a 6 GB file, and if the download is interrupted it will not continue on next connect but has to start over.
I do not think it is real time. A road that has opened up more than 6 months ago is not showing. Well, the maps (non satellite) shows it but navigation doesnt use that even though it is closer. Also, when I am on that road, it does not recognize it
Can the Googla maps history and saved locations be synced with Google maps on Tesla model 3?
@shabbir - If you're talking about history and saved location on your PC or phone, no they cannot be synced with your car. You can sync your calendar, and if you have an address in a calendar entry, you can tap it to navigate to that address, which can be very handy at times.
On the SW screen inside the car on my Model 3, there is specified:
Navigation data: EU-2019.20-10482.
This below the actual SW specification:
That should mean that the Map data was last compiled in week 20, or around June 2019. I live in Norway and also see several problems around new roads and also wrong speed data.
In the past, Tesla has updated the internal map about once a year, but that is for the S/X, not sure about the 3. The Google map should be up-to-date and match the web version fairly closely. If the Google map has errors, you'll need to contact Google.
Such a fantastic vehicle. Such a pathetic map.
The map is simply wrong much of the time, and therefore useless. As Montreal's largest and busiest interchange is rebuilt, the map is at least six months out of date, using roads and ramps that no longer exist, and ignoring the new ones, thus routing me elsewhere, as well as weekend closures.
It's apparently not rocket science -- Google Maps is up to the minute, all of the time, in real time. Can someone explain please? Is there a fix I'm missing?
Talk to your government?
@robertassaly - Have you never used an in-car navigation system? Tesla keeps the maps up to date far more than other automakers. I've found non-Tesla in-car maps to be at least a year out of date when purchased new. Then you have to pay $150 or so to get each year's map, which is usually a year out of date when sold and requires a dealer appointment to install.
So Tesla is ahead of every other automaker. As a bonus, it does provide up-to-date Google maps. Now the resident map in Tesla used for routing is not Google. Not sure if Google doesnt' license it or the costs were prohibitive. So you are right that for routing, it can be up to a year out of date. You'll have to wait for that next update or use your phone with an ad-supported map meanwhile. Could it be better - no doubt. Still, it is quite a bit better than other automakers already.
Typical in-car navigations are similar to that of a 2010 Navigon GPS device. They are horrible, have net zero traffic updates/info, are never updated and have horrible algorithms for determining the best route. Last i remember, Tesla maps use google maps for the map. Navigation and traffic info is not from google.
Unless i am wrong, not sure what you're talking about.
Composing requires energy, and force accumulates after some time. Actually, I have discovered that I need in any event an hour to get this show on the road and that three to four hours is perfect.
