Wireless car play. What am I doing wrong?


Recommended Posts

I got a 21 about a month ago. When I was setting up my phone with the salesman he told me I didn’t have wireless car play. I thought ok, maybe it had something to do with the chip shortage.

A couple weeks ago my wife wanted to hook her phone to it. Well it connected wirelessly for hers. So I made the truck forget my phone and forgot the truck from my phone. Repaired to the truck, still nothing. So I thought her phone is older than mine and may not have the newest update, maybe that’s the case, which it was. I then double checked my window sticker and it said I have wireless CarPlay. 
So today I had someone else in the truck with me. I had them try to connect their phone to see if the wireless CarPlay would work and it did. So I asked what version of the software are the using. They had the latest update just like me. 
I contacted OnStar and they said it shows that I don’t have it. I’m confused. Are there specific settings on my phone restricting it?  It takes me thru the steps like it wants to connect but fails every time. Any help is appreciated.

I would guess it is a phone issue. Maybe when your phone was first connected wireless was accidentally disabled. On your phone go to Settings > General > CarPlay  tap "forget this car" then try setting up CarPlay again.

It says wireless CarPlay in the standard options list. I actually got it to hook up today. The thing I was missing I guess 1) I had Siri turned off on my phone and 2) I never connected to the trucks built in WiFi. The trial for the data has already expired and it still worked. So I assume it’s good.

Think of the "wireless" in your truck like your wireless at home. You don't have to have (pay) an internet provider to make your wireless routers work. Its just a local network until you pay for service to connect you to the internet. So your truck has a wireless router in it. You can connect devices to it. They can talk to each other and to the truck's network (like entertainment). Then, if you want the truck to connect to the Internet, you pay OnStar to connect. Just like an ISP at home. 

 

Wireless CarPlay and Wireless Android Auto require a WiFi signal to work. Bluetooth is too limited, but still serves as the signal for phone.

That makes sense, but the other phones didn’t have to connect to the WiFi in order to work. They just connected thru the Bluetooth and CarPlay worked for them. I did try it again this morning on my way to work. I had to connect to the WiFi in order to activate CarPlay.  Which is fine, at least I can utilize it if I need it.  I just never connected to the WiFi because I had no intention of using or purchasing the data plan.

Yes- on your phone - go to Settings  ->General->CarPlay and follow those directions to turn it on
