Full Screen Carplay on Refresh

As many of you know, the refresh trucks have big screens for the infotainment system. For some reason, GM has not allowed Carplay to be fullscreen but Android Auto does have fullscreen. The way I got around this is by using a Tbox Plus from Carlinkit. These boxes allow you to not only do stuff like Netflix, Hulu, etc... on your screen, but also have wireless Carplay. These devices come preset to use Apple Carplay as the connection method to the car. This means the screen still won't fit fully. To fix this, you have to change the connection method by putting the attached file onto an sd card (format exFat), put into the Tbox Plus, and a message will pop up asking to change the connection method. Click Yes and it will restart and ask to connect an android auto device. And you are done! It sucks that you have to buy a device to get carplay full screen on these trucks. Fingers crossed GM decides to send an update to make this native.IMG_4077.thumb.jpg.f43e402b07fca4b66a440febb68214be.jpg

I have the one that is (4+64G) model. I believe the difference between the difference between this one and the (8+128G) model is the latter has 8 gigs of RAM with 128 Gigs of storage compared to 4 gig

I'm pretty sure you can't. Could be wrong though.

Thanks for the info. Glad you got it working  and as you said hopefully GM will make this native. No reason they cant.

I  am not an iphone user. You said "also have wireless Carplay".  Do iphone users not have wireless carplay to start with like Android users?

My only gripe is you cant pull data from your phone plan so without Onstar you dont have full functionality Something else GM could have easily done

I use a device like this on all 3 trucks. I honestly think this hack is one reason why gm is deleting wired car play from their vehicles.

The vehicle has wireless CarPlay. My main point was the CarPlay aspect. These devices also add wireless CarPlay to vehicles that did not have wireless CarPlay. 
 

Pull data from phone for what? The Tbox? You can connect the tbox to your phone hotspot if that’s what your talking about.

They still have wired CarPlay. They have wired and wireless on the newer trucks. The only way this works is because the box needs to run CarPlay through Android auto for it take use of the full screen. It just so happens that these boxes use wireless CarPlay.

I am talking about in my configuration. There are a few features that don't work without Onstar data. As an example the posted speed limit sign the sales guy touted. Does not work without a data plan.  Normally, I would not care but  I have a heads up display at the posted speed limit sign is quite nice.  This is different over the various years.  I have heard rumors the 2025 will not be the same.

I use the hotspot on my iphone, and have an automation that runs.  When the phone connects to CarPlay, it turns the hotspot on (and the truck will connect to that wifi hotspot) and then when the phone disconnects from CarPlay, the automation runs to turn off the hotspot. Works great for me and I can use the built in google maps.

That is an interesting concept.  I have Bixby automation routines for other things now. I might have to play with that for fun.  It would have to be automated and quick. My average daily trip is 10 minutes so do not want to mess around connecting to phone, etc just to have functionality.


But that is great food for thought. Thanks!

Thank you, ordered! Appreciate your research on this.

I’ve tried a few different devices for getting cat play full screen mode, but not the exact device you used. 
 

All of them I’ve tried do technically get it full screen, but each has other issues. One didn’t allow the mic to work with Siri at all. She wouldn’t even read text messages. The other produced a massive echo when making phone calls. 
 

Does this route have any issues?

Glad I could help. Some things that are aggravating is when you turn the truck on, the truck auto switches to that sound output, even if nothing is playing. I like FM radio. When I turn my truck on, it plays then it switches sources to the device a few seconds later, so I have to manually change the source back to FM. Also, whenever carplay does output sound (Siri, navigation, etc...) it changes the source to that and doesn't switch back. I know that's a GM issue because my 2019 would change source to carplay and then not change back. If anyone knows a fix for that, that would be awesome.

      Thanks!  I figured as such; GM and other manufacturers have used standard parts and harnesses across trim levels and such for decades.  I pulled the blank accessory cover off of my commuter van (a 2016 or so Chevy 15-passenger) years ago and found the plug for a USB outlet.  It wasn't connected to anything, though (I tried swapping in an outlet from another van).  I was a GM Tech years ago (late-90s) and was pretty familiar with my 2006.  I might be wrong, but I view newer vehicles (pretty much anything made in the past 20 years) as being a lot more plug and play.  Meaning, more unused wires and plugs unless you have the Mack Daddy of vehicles.

      not all plugs will be used.  gm uses more generic harnesses that support most/all options, and if your truck doesn't have a specfiic option, the plug won't be used (commonly will have a dummy insert in the plug , or it'll be taped up, but some may just be left as is).  But it's sldo possible some p.o. has installed the wrong/cheaper parts that aren't correct for your vehicle...

      First off, I'm not trying to just get easy advice/fixes for the issues I've noticed so far.  I'll be combing through the site via searches and such, and if past experiences are any indication, should find what I need.  For the sake of conversation, though, I figured I'd post the handful of things I've noticed in the 12 hours since buying my 2010 SLE CCSB.     Indicator lights: Airbag and TPMS.  The tire pressures aren't reading for any of the wheels, so I'm pretty certain the sensors were either removed, are damaged, or are otherwise inoperable.  I used to mount and balance tires 25 years ago but am pretty much ignorant when it comes to TPMS.  My 2006 didn't have the sensors and this might be the fourth vehicle I've owned that does.     Radio: Rear speakers aren't working.  I removed the driver's side rear door panel and checked the speaker and wiring.  I also removed the sill and b-pillar covers to check the wiring.  A few minutes of Google Fu showed that this is potentially a head unit issue.    Switches: Power mirrors don't turn left/right.  I ordered replacement driver's door switches that should arrive tomorrow.  The windows and locks work but it was only about $20 for all of them.  The driver's side rear window switch lets the window down but won't put it back up.  I think the passenger rear doesn't work at all.  In the coming days/weeks, I'll break out my multimeter to check all of that.   Unknown wiring harness: There's a box attached to the front driver's side of the engine compartment, right where the second battery shelf is located.  There are three plugs, one of which looks like it fits a standard headlight-style bulb (9007 or similar).  It doesn't look like it's plugged into anything.  I'll do some digging and if I don't see anything elsewhere on the site, post some pictures here.   Unknown plugs on brake booster: There are at least two female plugs on the brake booster that aren't being used.  I think it might be a replacement/aftermarket, so maybe those are used for a different application, as there don't seem to be any unplugged harnesses and no indicator lights are on.   Little squeaks when turning: Sounds almost like a bushing around the bed of the truck.  I'll have to pay close attention as I get more familiar with the truck.   Clunk on acceleration: possibly the infamous drivetrain clunk.  My 2006 had it and I'm just not familiar enough with this truck yet to fully grasp what it is.   Anyway, my apologies for the vague and all over the place post.  This truck is new to me, and it's been four years since I drove my 2006.  With 200k miles, I know I'll need to learn this truck quickly to avoid having any major issues, despite being confident it's got much more life to it.  My 2006 had nearly 320k on it when I parked it (nearly 300k of which I put on the truck), and it was still drivable then, though I suspected the head gasket might have blown.  I'd hoped to have that truck back by now, but it's gone forever, as I detailed in my reintroduction thread.
