Member suggested I start a new Thread on the subject of getting Road Speed to Display on Dash or HUD as it had with the month free OnStar in my 2024 E-Ray 3LZ.
Background and his post:

Background:
Had free trial OnStar for ~one month, then canceled. When OnStar was connected had Road Speed showing in HUD or Center Dash display depending on drive mode.

Now using Apple CarPlay connected to my iPhone 15Pro for Nav. Had an issue, solved by selling CarPlay ICON phone to ON for Cellular Data.

Have tried turning Car WiFi Off and ON as well as my Phone Hot Spot Off and On.. Still no Speed Showing. Just tried a verbal NAV request to Siri while driving locally. When it is directing there is a small Speed Limit sign on the center MAP display. Once I reached my destination. no sped limit sign on Map!

Anyone with a 2024 not paying OnStar or Google a fee getting speed limit to show on Dash or HUD?

Mine shows and I’m not paying for OnStar or Google. Now it doesn’t show ALL the time, but does most of the time. I’m always in CarPlay and WAZE is my navigation App of choice.

Try using WAZE in CarPlay and see if that’ll get it to display. Even when I tell WAZE to stop, it’s the background App I have running navigation in my ‘24 and the speed will display on my dash. I don’t have HUD in my 1LT, so no idea if it’ll show there too.

Is yours a 2024? When you say on the dash, do you mean on the infotainment screen or on the display behind the steering wheel?

BandDirector

Mine is a ‘24, and I do mean on the dash behind the steering wheel, not just the infotainment screen.

…you can see the bottom portion of the speed limit sign display to the upper right of the tach…I’m in a 45 MPH zone…

Are you only using CarPlay or do you also have your car setup to connect to your phone's hotspot?

BandDirector

CarPlay ONLY. Phone automatically connects when I start car because I also use the Sirius XM App in CarPlay once the trial ended…I ALWAYS have CarPlay on. I don’t have my phone’s hotspot activated because Verizon wants another $10 per month…

BandDirector

…now it is possible it’s picking it up from one of the other Navigation Apps I have available in CarPlay. I also have Google Maps, Apple Maps, Here We Go, in addition to WAZE all available to me in CarPlay, but WAZE is the only one I keep active…

BandDirector

…one more theory…in WAZE, the speed limit sign doesn’t display until you exceed the posted speed limit when viewing the infotainment screen, I know in the picture I posted above, I’m doing 40 in a 45, but I’d just slowed down to snap the pic. I suppose that could explain why I said my speed limit sign doesn’t always display on my dash…it’s possible it only displays once you exceed the posted limit…just another possible explanation…

RKCRLR

Yea, I don't like that, my wife's car does the same thing. So if the speed limit isn't displayed you don't know if it is because you aren't exceeding the speed limit or you are exceeding it but it doesn't have the speed limit data.

BandDirector

…I just found this in my WAZE settings…gonna turn on ALWAYS display speed limit and see if that changes the consistency!

BandDirector

…and one more thing I just found in WAZE settings is Google. Forgot that Google owns WAZE now, but that may be why the speedometer display works on the dash as well…

I have a 2024.. had it over 6 months. So any sort of trial of anything should be long gone.

The speed limit icon on the HUD and dash just doesn't seem to display consistently. I messed with all the settings, and I'm aware some drive mode just don't display it. It'll work on some days and not others. I haven't been able to figure out any pattern to it. It either works for the entirety of the drive I'm on, or it doesn't. The "only displays when you are speeding" theory definitely isn't the case.

These cars really just seem to have some buggy software.

I always use the speed indicator in my 2024, no OnStar. I am talking about the speed limit shown in digital instrument cluster.
I HUD does not show it, only current speed.

Great Info. Had WAZE in prior Vette but for my rural drives not useful. BUT will try IF that gives speed limit.

Have your dealer check the nav card.

smithers

2024’s don’t have the nav SD card

JerryU

So you're seeing the road speed limit? As I said i was when I had the free OnStar trial for a month but not after I canceled. Are you paying the GM/Google monthly NAV fee?

Swolejack

I had the traffic sign on the driver display initially then it went away. I do have the Onstar
subscription and I have my Iphone settings for Google identical to previous post. I still
don't have the speed limit sign though. I called Onstar and they said take it to the
dealer (I'm assuming the Onstar guy was clueless) I really like (liked) this feature
when I had it. Using Waze doesn't bring it back either.

Red Mist Rulz

Interesting. Yours is the first report I've seen where the speed limit shows on the car without either a subscription through OnStar or using the phone as a hotspot. Wonder where it's coming from.

CorvetteSparky

From my experience it won't display all of the time. Only when the speed limit for the road you're on is contained in the nav database. There a several secondary roads in my rural area where the limit is not displayed however it is on all major roads and freeways. However, I haven't downloaded Google Maps for use where there is no cell reception. But my theory is that if the speed limit isn't in the database it's not going to be there whether downloaded or not. Sorry, I'm no help when it comes to never being there.

Howe are you guys getting Waze to work? I would certainly prefer that to Google. Are you just bringing it up on your phone after connecting to the car?
