Navigation System update

Navigation System update

How can I update the navigation system my 2017 P100D?
It does not recognize road changes which occurred within the past 2 years.

Is you car connected to WiFi? That is the best way to get updates (Both software and maps)

Aerodyne | June 25, 2020

I just did my map update...full wifi signal, took many hours.

barrykmd | June 25, 2020

Aerodyne - When you say you "did" it, did you request it somrehow or did it just happen to update?

mbirnie51 | June 25, 2020

@Tin...first we'd need to know what version of navigation you are presently running. The latest is Nav: 2020.12.11866 .
You can find what your vehicle is running in the SOFTWARE screen in your car on the UI. Next, you'll need a very strong Wifi connection to download this massive data dump. The 2017 vehicles are relegated to 2.4G Wifi unless you've done an MCU2 upgrade. 2.4 G means a wider range of Wifi, but less data transfer per second. So if you do your regular OTA updates lets say in your garage and the strength of the Wifi signal is less that 5 bars, your vehicle will struggle to do the navigation download. 3 to 4 bars will suffice for the OTA update (less data transfer) without Nav upgrade, but trying a Nav update will be iffy. Put a Wifi extender in your garage to make the signal as strong as possible.
With an MCU2 upgrade, the vehicle goes to a 5G protocol and that allows greater data transfer per second but sacrafices the range it will extend to; making the strength of signal just as important if not more.

I repurposed an older Linksys router and hard wired it in my garage back to the modem to "extend" the range of my providers Wifi signal because I have other devices such as cameras and Alexa at that end of my home that suffered from signal strength.

@tln2629: If the map is not showing road changes, a navigation update won’t fix that. The map comes from Google. The navigation data in the car is GPS data used for navigation.

Check Google Maps on your computer or mobile device and see if the roads are incorrect there. If so, report the issue to Google. There’s a way to do that directly from Google Maps.

Looks like a few more lines of code needed in the nav/camera link. Last year Minnesota / and I assume some other states / raised a high percentage of state highway speed limits from 55mph to 60mph. I noticed that as I hum along at 60 the nav/camera doesn't link the "60 MPH" roadway signage onto the driver annunciator panel (da-dashboard) and "55 MPH" and the Nav-system limits the attainable forward-speed to like 57MPH during navigational route/lane following. Hey there software peoples please B fixing this. /s/da-WileyFlier

EVRider | June 26, 2020

@jbyanda2016: The car doesn't read speed limit signs currently, so the speed limits come from the GPS/navigation data. If you're using AP on the highway, you're not limited by the speed limit.

barrykmd | June 26, 2020

AP1 cars read speed limit signs

EVRider | June 27, 2020

@barrykmd: That’s right, but I assumed the post was about a newer car because it wasn’t reading signs. | June 27, 2020

And AP1 cars car often misread signs. You really shouldn't go 80 mph on the 80 freeway here in California. AP1 cars in Europe often pick up a max speed sign printed on the back of trucks as the speed limit and go far lower than the car speed limit.

Database design is not perfect either but can get better. Ideally, a merge of sign-readings and the use of a database might be the best solution. Then again there may be patents that prevent Tesla from using sign reading as this was done by Mobileye, which is no longer used by Tesla.

EVRider | June 27, 2020

@TeslaTap: I think Tesla intends to add speed limit sign reading, since this would be required for true FSD. The database doesn't get updated in real time. I would expect that only HW3+ cars would get sign reading. | June 27, 2020

@EVRider - I agree, but sign reading by itself needs far better processing than what Mobileye did. HW3 should have the power needed. Still, a database sanity check would be wise. A couple of times I've come across a defaced speed limit sign - 55 was changed to 85 in one case I saw. Some logic can filter these kinds of issues such as the maximum speed limit in a state. There are also plenty of areas where the speed limit sign is obscured by greenery or trucks in traffic are between you and the sign. In those cases, a database may be required to know of a speed change at a specific GPS spot.

EVRider | June 28, 2020

@TeslaTap: I totally agree, wasn’t suggesting that the car should only use signs. I think HW1 used both GPS data and visual data.

I’m curious to know how Tesla handles discrepancies between visual and GPS. In your example of the defaced sign, you would want the car to ignore the visual data, but if there was a temporary speed limit change due to construction, you want to ignore the GPS. Not sure how the car decides which data wins.

jerrykham | June 28, 2020

@EVRider - good question actually. It probably has to fail safe to the lower value, but could probably have a confidence level that would allow it to avoid having to fail safe in many normal scenarios. For construction, I would have thought it would work lower the confidence in the map data (and go more with the posted signs) when the car identifies cones or other markers. But today our cars see fire hydrants as orange cones. So they need to improve that too and then they should be able to figure out things like, "this is a construction zone, speed limit signs get a higher confidence rating here especially if they are lower than the map data".

Tldickerson | June 28, 2020

Is it to hard to just take over when your in a construction zone? I cannot believe the amount of people that want the car to drive you by itself when it just not that safe. Use the system on the freeways and use your own system on surface streets and construction zones. Would you like people trusting it in school zones where your children go? Maybe in the 25th century they will have a better system like the Jetson's had on tv.

EVRider | June 28, 2020

@Tldickerson: The question is how the car is going to handle these things when no one is driving.

Yodrak. | June 28, 2020

We can worry about that when the rules of the road allow that no one is driving, but that's a ways off. Right now, some one is supposed to be driving.

Tldickerson | June 28, 2020

@EVRider, right now that isn't the case and I doubt that any of us will be around if and when that time comes.

Tropopause | June 28, 2020


Tldickerson | June 28, 2020

Really Trop, let's just wait and see when that will even be allowed in the states or anywhere else for that matter.

Tropopause | June 29, 2020

Well I plan on seeing it in my lifetime. Either you're very old or very ignorant. Which is it?

NKYTA | June 29, 2020

Can’t it be both @Tropo? ;-)

Bighorn | June 30, 2020

Some states already have legislation that allows for self driving cars. Tokyo was set up for it at this year’s postponed Olympics.

Aerodyne | June 30, 2020

Barry....I got the nav update right after updating to 2020.20.1. even under full wifi signal, took overnight to load.

jordanrichard | June 30, 2020

With recent updates, has Tesla solved the problem of cars while being summoned, driving down the middle or wrong side while moving through a parking lot?

Tldickerson | June 30, 2020

@Tropopause, if it matters some here know I'm 73. I don't doubt that in the future there will be people movers but I cannot see parents putting their children in a car by themselves and programming the car to take them to their destination, dropping them off and then the car returning home so you can use it. I still feel that something like that will happen when ALL cars on the road are able to safely do it. Just my feelings. | June 30, 2020

@ jordanrichard - Who knows? Considering us humans can't deal with it either. FSD doesn't mean it handles every nutcase on the road, but hopefully, handles it better than most drivers can.

@Tldickerson "...I doubt that any of us will be around if and when that time comes."

I guess that makes sense if you are planning to die in the next couple of years. With COVID, sadly, one doesn't know.

Tldickerson | June 30, 2020, so you really think your going to be able to set a destination in the next couple years and just sit in the seat and watch while your car takes you there without ever having to take control of your car?

barrykmd | June 30, 2020

Aerodyne - Thanks. I checked and I have the current version. I have no idea if the SvC center installed it when they replaced my MCU1 in March or it downloaded behind the scenes while parked.

NKYTA | June 30, 2020

@Tld, my wife sat in the drivers seat in September of 2016, I sat in the back for the demo. The car drove itself, entirely. Stopped at stop lights, stop signs, merged on to three different freeways. And returned itself to the Corp mothership on Deer Creek. All automagically. Very much the same as what Tesla put out as “their marketing piece” which I’m sure you’ve seen. It actually happened, I was there in the back seat.

This was back in the MobileEye days, but TM deemed it limiting, so the higher powered processing is now in place.. Build your own better processor, build better software.

2 years is a stretch, 5 years from now approaches better than 99% of humans - better even than those with Lidar. My prediction, TM wins over Google.

Google is not going to build a car you want to buy, they might supply, say Ford, with something substandard.

Tldickerson | June 30, 2020

@NKYTA, you say in 2016 you were in a Tesla that stopped at stop lights by itself? They just came out with that on new cars just a few weeks ago. My car has the MobileEye feature and it does not do that. Can you explain that to us here in regards to how it worked then and then didn't for 4 years. Sounds to me like they had somebody remotely controlling the car, which is very strange.

Tldickerson | June 30, 2020

My bad, it sounds like you weren't in a Tesla but in a Google car. Excuse my mistake.

NKYTA | June 30, 2020

@Tlld, wrong yet again.

It was demo. On a known track back then. To show what could be done. Which included everything. Stop lights, and freeway interchanges. I was sitting in the back seat.

I don’t think you understand what TM is trying to do.

I don’t think you have the smarts to understand.

I won’t ask you to understand a major chip change when you can’t understand how your car works.

Tldickerson | July 1, 2020

@NKYTA, so I'm not smart? Your a smart A$$. I don't need your stupid remarks.

Bighorn | July 1, 2020

IQ does drop significantly by 73 in almost everybody. The good news is that part of that “decline” has always been being less intelligent based on being born in the olden days—Flynn effect.

barrykmd | July 1, 2020

NKYTA - Stop picking on TLD. He's one of the few people here with Koolaid antibodies who speaks the truth.

Tropopause | July 1, 2020

He and Darth are like Abbott and Costello.

Tldickerson | July 1, 2020

@Tropopause, your probably part of F-Troop that use to be on TV. | July 1, 2020

@Tldickerson - On FSD - yep, I expect it within 2 years. Now I don't expect it to handle dirt roads, whiteout conditions, hurricanes, lava flows, and other rare situations. For normal roads, from my house to the office and back, or house to a store and back, I don't expect any issues. I'm not saying this is a trivial task, but the technology is not that far away.

One unknown is the regulatory part. We may have to keep our hands on the wheel, until regulatory approval. Approvals could be quick or painfully slow.

NKYTA | July 1, 2020

@barrykmd, I don’t suffer fools. I don’t mind that you “don’t drink the koolaid”, but I don’t think you are a fool.

@Tld “ @NKYTA, you say in 2016 you were in a Tesla that stopped at stop lights by itself?”

That is exactly what I’m saying. Ever hear of Alpha software?
