As soon as my one free month onstar expired I lost the wifi hotspot and now wireless CarPlay will not work. Deleted the phone on the radio and deleted the device on my phone. Did the set up again and it only connects bluetooth. I try to connect wireless CarPlay and I get the failed message and to try again. Will not work on my phone or my wife's. Dealer time or is it because there is not wifi in the car now? Worked great for a month on both phones...now...dead.
Thanks for you time....Matt

Do your phone plans include wireless data?

(eg from AT&T, or whoever if your phone service provider is)

The fact is that Android auto uses internet connectivity for many of its features, such as Google assistant.

It's true that you do not need to pay OnStar for wireless data, but in that case the wireless data needs to come from your wireless phone provider. The data connection has to come from somewhere.

If you manage to get Android Auto to run without any wireless data connectivity at all, then many of the features will have no way to function.

RE bluetooth:

Most connections between phones and car radios use Bluetooth. This is how most hands-free calling implementations work, and you can also stream music over Bluetooth. However, Bluetooth connections don't have the bandwidth required by Android Auto Wireless.

In order to achieve a wireless connection between your phone and your car, Android Auto Wireless taps into the Wi-Fi functionality of your phone and your car radio. That means it only works with vehicles that have Wi-Fi functionality.
However, Android Auto can use bluetooth to help establish the WiFi connection as well as to function as an ancillary connection in addition to the WiFi.

There's a shocking amount of misunderstanding and misinformation about this technology.

When I met my sales person he got in the vehicle and the first thing he did was setup my wireless Android Auto and it worked fine. He then went on to do the usual run through of the vehicle. At that time AA worked wirelessly. He told me to push the Onstar button on the way home to setup my account. I did that and ever since then my AA did not work. I troubleshot it with Onstar with a couple of different reps. with no luck. Also they cannot get my wireless ATT connection working. The told me to take it back to the dealer. I just want AA for Waze & maps. It does work on the wire

I assume you do not mean that your phone's data connection is not working on your phone, and that you mean you have been trying to share your phone's data connection to the car. If you can use your phone to connect to the internet via cellular (eg 4G LTE. 5G, etc) without being connected to any WiFi, then you are set.

Don't share your phone's data connection to the car.

What version of Android do you have? I had trouble getting Android Auto to work and I contacted [email protected] and told me I had to have Version 9 or higher, I had Version 8. I went to Version 11 and have had no more problems.

I had that problem when I first bought my Trailblazer. My old Samsung phone was 7 or 8, but about a month later I upgraded to new Samsung which had 10 and then it worked fine. I also needed version 9 or higher to work with my F800 dash cam.
