This thread is totally mixing up terms and issues. Former GM infotainment engineer here. The GX has the newest Info 3.0 system.
#1) IMO,
Android Auto (and
Apple CarPlay) are superior to any built-in BT connected options or built-in apps. It will totally alert and read your texts (and allow you to respond via voice). It will play Spotify (allow you to select playlists, songs, etc.) AND by plugging in, your phone will be charging (faster than your mat). It gets and keeps the phone out of your hand and gives superior integration.
#2) WiFi: You do not need to subscribe to the $15 WiFi plan. This turns your car into a hotspot, allows your phone to use your car’s (AT&T) data instead of your phone providers. Or passengers/kids to connect to it. Another subscription most don’t need...because we already pay for it on our phones! Useful if you have a low data cap on your phone. My guess in what your dealer was suggesting - to use the Buick apps on the radio (or downloaded from the Buick App Store on the radio screen), the radio needs data. Hence, paying $15/month for the data plan gets you this. My opinion - Try
Android Auto, so much better.
Suggestion: See if your dealer has a trained tech expert, and set up a 30 minute session. Explain what you used to do and desire, but be open to change - it will be better, give change a chance. Or buy an older Encore.
Another alternative - no reason why you can’t play the Spotify app on your phone and have it stream via BT to your car. Assume this was your prior method? Again, get the dealership tech guy to help. Texts over BT are still built-in to listen, just like your prior Encore, too.
For others in this thread...
Wireless CarPlay/
Android Auto: These use a WiFi connection between phone/car to get the required bandwidth. But totally different from how existing WiFi connections are used by a phone. Just know it’s wireless, sets up seamless, and doesn’t impact any other wireless connections.
