road sign recognition with Safety Sense

I thought it used the navigation system to ascertain and show me the road speed limits on the current gen 4 with atp and pcp.

Then again, I noticed the euro spec ones can detect traffic lights etc..

 

In the US, people put black tape over the camera holes on their PCs and tablets, and they think that On* (and Toyota's clone product) is an evil plot hatched by dot.gov to track its citizenry while they drive.
They don't even allow traffic cameras in some parts of the US.

I'm thinking that it's going to be a few years before this takes root in the US.

 

You use a cellphone? Or a modern Intel based pc? Then you are being tracked anyway.
Might as well use the amenities provided.

 

I know this is slightly off, but how is it able to tell you "heavy traffic up ahead" as mine did driving down from Connecticut to New York on the I-95? There was indeed heavy traffic up ahead.

 

I'm 99.9% certain that the system uses and connects to a designated mobile phone service provider as does my ram 1500 via its Uconnect head unit .
Its independent to your own cellphone / mobile device. And yes, these systems can possibly know exactly where you are at anytime. One feature being that it can track a stolen vehicle or if you press the SOS button they can send help your way without you having to tell them where you are.

Must be XM as I have no data plan

 

I can turn my cell phone OFF.
In fact, when I drive....I DO turn my cell phone off.

Actually?
It's not my issue. I have On* and I'm not part of the aluminum hat crowd.
I'm a staunch red-light camera fan, and I have no problem with vehicle data-loggers like my company uses with my Prius.

I'm just advocating awareness.
I don't need my car to read road signs for me.

 

We have it on the map as well, which is a good thing as the road sign recognition doesn't always see the last speed limit sign if it was as you turned into a junction and still displays the previous one, whereas the nav (if up to date) knows where the limits change and it changes on the map.

 

in the UK it works off RDS Traffic announcements.

 

It was the same when I lived there until 2008.
I think I may have been talking about a different thing. I was talking about the radio transmitter and receiver the head units currently have on board. I know for a fact that some Chrysler Uconnect systems use a mobile cell masts to determine location of their customers vehicles in an emergency scenario, independent of the owner having a mobile phone or not. In effect the head unit is an always ON two way radio.

I think the Toyota system on our ( us spec) current Prius 4 used the same principle.

LG-H901 ?

 

Is it good (quick) at updating?
Our RDS system sucks most of the time. On the previous Prius+ (v) system I have had the roads on the map turn red, indicating heavy traffic, when there's none and no indication where there is heavy traffic that has not just appeared. It seemed to be very slow to update.

 

Not sure , I still haven't managed to get my navigation to "talk" to me. LOL

LG-H901 ?

 

Mine's always arguing with me when I ignore it........"take a u-turn" is the most common phrase.

 

Rub it in why not ;-)

LG-H901 ?

 

Looks like Entune does get traffic info through HD Radio (which is AM and FM digital broadcast) too:
