Apple CarPlay and Google Maps/Waze

[marpel]

'22 Sierra HD.

 

Know pretty well nothing in this area, so not even sure if I am asking the right question(s).

 

When I first set up system, was able to use Google Maps/Waze without having to hardwire iPhone. Just kept phone on hip. Of course, also able to access telephone contacts etc.

 

However, have discovered that the phone really loses power, and have read somewhere that Google Maps etc work in the background, even when not visible on the  dash and draw iPhone power as a result.

 

I do not use Google Maps/Waze much (use OEM navigation) and only in some rare cases may use either.

 

A while ago, I thought I read a forum post (which I can't find or even recall which forum it may have been) about being able to disconnect the use of Maps/Waze wirelessly, but being able to access either by just plugging in the phone, and that prevents the constant power loss. And, of course, the phone gets powered while plugged in.

 

Tried reading the Manual on this, but it all read like Greek to me.

 

So, is there a way to have Maps/Waze available only through wired connection and not wirelessly. Or is it an all or nothing arrangement?

 

The wife had me turn off a number of things on the phone, but when I turn on the truck, I still get the "Apple CarPlay Connected" and I can access Google Maps without plugging in the phone.

I don’t know if I fully understand the question but I’ll give it a whirl. I use my iPhone for everything. When traveling I use Gps navigation and IHEART radio on my phone through Bluetooth. The phone is plugged in. I also click it over a vent to keep it cool because they get hot. I ran a cord for charging out of the way. My favorite spot is to the left of the steering wheel. I don’t use my cars navigation. Non are as accurate as WAZ or my standard iPhone navigation. IHeartRadio doesn’t have station fading like standard FM. I don’t eliminate my icons when done I just x or swipe off.

Waze is famous for draining your phone battery and running it hot. I didn't think Waze, Google Maps and Apple Maps (my new favorite of the 3) would load and run on your phone unless you select them from the CarPlay screen or launch them on the phone while connected to CarPlay.  If they're running in the background on your phone, try killing them before connecting to CarPlay.

Thanks very much for the replies.

 

As a result of some, fairly regular, travel outside cell coverage (mostly during trips to/from Vancouver, BC and Denver, Co), I got used to using the OEM Navigation, but still have occasion to use Google Maps and Waze within the greater Vancouver area and/or Metro areas. So would still like access to both, and currently have the Apps downloaded on my phone.

 

When not in the vehicle, I have noticed a much less power drain on the phone and when in the vehicle, especially on long drives, the phone uses more power, even when not using Maps/Waze. When I drive, even locally, I don't use any extraneous Apps and in fact, very very rarely even turn on the radio. I usually have OEM Navigation running. Because this power usage seems to be associated with using the truck, I merely thought there was a (wireless) connection between it and Google Maps/Waze, even though they are not visible on the dash screen (playing in the background??).

 

So, as initially stated, I was wondering if these Apps could be set up on the phone, so they will not wirelessly operate in the background (if that is actually what is happening), but would be accessible if I plugged the phone in to the USB port in the truck. What I would prefer is not having to go into my phone settings and turn things off/on each time.

 

So Njmurvin, is that what you mean by "try killing them before connecting to CarPlay."?

 

Thanks for any added advice.

What I meant by killing them is force-closing them. Depending on the phone you have it's either a double click of the home button or, if you have a later phone with no home button, it's a up swipe from the bottom of the screen. Apple tells you that these apps don't use any resources or drain battery but my experience in the past with Waze tells me otherwise. As a result, I make it a habit to force-close Waze after I arrive at my destination whenever I use it.

Thanks very much Njmurvin. I will give that a try.

Killing the app will help but not much. What's eating up the battery is because your phone is connected to the infotainment wirelessly even though you are not accessing Apple CarPlay on the infotainment. If you only want Apple CarPlay to be connected through the USB cable then you need to go to Settings on the infotainment then Phones and delete your iPhone listed there.  You will also need to delete on the iPhone in the Bluetooth settings the GM app.

The downside of doing this is you will no longer be able to stream your iPhone music to the radio. Everything will now ONLY be accessible through the USB cable when plugged in.

I do like NJmurvin does on my android phone:  Force close the apps after getting into the truck and starting it.  Works great. 

Then to use the app connected to the truck I simply start the app on the phone.  Hope it works the same for you with the iPhone.

 

Happy Trails!

A few things to try,my android phone allows me to turn off auto start of andriod auto or not allow it to start when phone is locked. I also have a button to allow wireless android auto. When i use it in the truck, I have the console which has the wireless charger in the mat where I lay the phone. That keeps it charged. If you have a lower optioned truck, they make an aftermarket charger that will retrofit into the center handrest. So i never have the phones plugged in.

In Google Maps there is a option to save route for offline use. You don’t need service to use it if you save it there.

Late to the conversation but I'm not seeing this answer anywhere here.....

 

There are three ways to connect your phone to your truck; USB, Bluetooth and WiFi.

If you're seeing Waze in Car Play and your phone is not plugged in, you're connecting through WiFi. This combined with Location Services (GPS) used by Waze WILL pull your battery down faster. I suspect that Car Play is starting the Waze app even if you had it shut down before starting the truck.

 

To stop doing this, Go to your phone's WiFi networks and delete / forget the trucks WiFi network. Doing so, you will loose wireless Car Play services like Waze but you can still play music and take phone calls. And Bluetooth has a much lower demand on the phone battery. If you really want Waze or other car play services, you can always plug the phone into the truck's USB.

 

One more thought about your truck's USB. It only provides the 2.5 watts of power specified by the USB 2.0 specification. That means your phone will only have the slow charge option available and the combination of GPS and WiFi will consume a significant portion of that. Unfortunately, it appears that the USB C outlet has the same limitation.

 

Hope this was helpful to someone.
