Nav System: A brief look

That is exactly correct. The maps are downloaded dynamicly via the cellular data connection.

I am baffled. I thought the tech package had a nav system with locally stored data and does not rely on cell coverage.

I thought the navigon had its own maps. It says 7 years of free updates to it. I assume it's not in yet if you don't have it.

I'm guessing this is it -- otherwise, why would we need years of free updates if we're simply pulling the maps from the server anyway? Something else Tesla needs to clarify.
 
Thanks for that, Cottonwood! Loved the part about the 23,496 mile estimated range; you could have almost circumnavigated the earth :)

The nav part is still a mystery to me; if it's Google Maps that needs to fetch data over a wireless connection *even with the tech package*, then, what's the bit about "turn-by-turn navigation with seven years of free map updates" on the Model S Options page? That applies to the display behind the steering wheel alone?! We'd have to have a connectivity plan to see maps on the main screen, I presume and that works for Sigs which have one year's worth of wireless connectivity paid for?!

Questions, questions...
 
Guys -

When you have the tech package, you have in essence 2 navs. Google maps on the main 17" screen and a "traditional" nav with preloaded maps that is displayed behind the wheel on the left side next to the speedometer. Google maps in the main display requires a data connection to the Internet so that's why it cut out on cottonwood.

Now whether you need to calculate a route before you can get it to display behind the wheel, I don't know, but in my test drive on Monday, I was following a route the tesla store manager programmed into the nav behind the wheel while google maps was also displayed on the 17" screen.

Sorry, Cottonwood, we are going off on a tangent here and getting away from your story...

Aaron, what you state seems to be what's happening, yes, but, isn't that a terrible waste of the 17" screen for actual nav situations? More than that, having to pay for the data plan to see the maps on the main screen sounds lousy. If I don't pay for a data plan, I'll see blank tiles alone, I guess?!

So tired of the lack of details on any of these things on Tesla's website. Unfortunately, the product specialists don't seem to know any more either so, not much of a point in pinging them...
 
You don't have to pay for data plan. Connect your phone via USB and you are good or use wifi hot spot. I'm kinda surprised the navigation is only behind the wheel, but now Its starting to make sense to me how this works. I'm only confused on how the two interact e.g. Do I enter address on google maps And it navigates with navigon?

Umm... Even for tethering via USB or WiFi, one'd have to fork out the tethering charges to ATT ($20 per month, I think) or other carriers. Lame and costly to have to do that to see maps on all that real estate after paying so much for the tech package already.

Yeah, the only address entry point for starting turn-by-turn nav (until voice control comes along) is through the maps app.

Even so, tethering can be useful for other things, such as laptops, and sometimes come included with corporate plans (which, I would presume, a lot of Model S buyers have). I would say being able to use a smart phone's tethering for the car's data on the road (can we do that? confirmed?) is much more useful for most people than being able to use the car as a hot spot like Elon was talking about.
 
Yet another reason that they should have used Android to power the 17in console. This is still wildly inferior to the built in nav and maps in Android.

If you have an iPhone, you have no idea what you are missing out on.

Looks like I will still be using my Nexus 7 in a dock for navigation, and unless I can find a way to mirror my phone screen onto the console. Pity, they put so much time and effort into building something that is simply blah when something better was available to them 100% free.

Tesla, how about DLNA support as a future upgrade? =)
 
So, at work we park underground, anything below level 2 get zero signal. Verizon and AT&T both get nada signal, zilch. So does that mean I can't enter a destination until I get signal? or does Navigon do the work and google maps is strictly for where are you now GPS tracking?

Only problem with tethering and not having a separate wireless for the Tesla would be remote access. The iOS/Android App wouldn't be able to communicate with your phone unless you were within hotspot distance.
 
I suspect that on-board storage of maps is planned for a future software upgrade. People have Tesla reps on record of the tech package supporting this--I think a lot of the concern is due to much of the software being in-work.

I hope this is true, as I would be really upset if in the end on-board maps are not supported. Yet another area where Tesla needs to improve their communication. I'm OK with having to wait for it, as I understand there's a lot going on and we're still in early deliveries. But I don't like being in the dark about what specific features are and are not expected with the car purchase.

Can those who have received their car verify that the Nav system to the left of the speedometer and the 17" display Google map are two separate Nav systems? When the 17" display Google map cuts out because of poor Internet reception does the Nav system to the left of the speedometer continue to work properly? Is there a pointer on the Google map showing where your car is? Thanks.
 
Just to underscore this issue for any Tesla employee reading this: the Tech Package nav system must be able to work in areas without cell coverage. There are large swaths of the U.S. and Canada with little or no coverage, but where GPS coordinates are available.
Let me emphasize what Robert said - It is absolutely essential that the Nav system work without cell connection! If I can't navigate in the boonies, it's useless.
It would be very cool if the car used speed and steering angle sensors to do dead reckoning if the GPS couldn't see enough satellites. This can be a problem in forests.
 
I was just scrolling through the pictures in the latest Edmonds review (http://www.insideline.com/tesla/model-s/2012/2012-tesla-model-s-full-test.html). I noticed one of the image captions says the following:

Edmonds said:
A quick tap expands the upper half to full screen. Incidentally, the map is Google via a 3G connection, but duplicate map data is also resident onboard when 3G isn't available.

Maybe Elon has a newer software revision (beta?) in which onboard maps is enabled? Maybe Edmonds is just passing along what they've heard from the sales folks?

Either way, it looks like onboard maps should be coming. I believe Cottonwood said that access to the onboard hard drive hasn't been enabled yet. Perhaps onboard maps will come in the same update?

Also possible they meant the maps that show on the dash
