Replacing 2.0 HMI module with 2.5 HMI module to add CarPlay/Android Auto to 2014-2015 Silverado

Recommended Posts

For anyone interested I believe I will have the ability to do programming very soon. I have made quite a bit of progress and hope to have the reprogramming method refined and ready within the next few weeks. Please stay tuned. You won't wanna miss this ;)

Sounds good and good luck. I’m hoping that you’re able to just program the radio and it will work instead of having to also reprogram the HMI along with the radio.

I`m hoping that will be the case as well. I`m waiting on some hardware to come in. I will commend the people offering the programming, it is certainly not easy. There are a lot of hurdles to get over and there is quite a substantial initial investment for everything that`s required.

 

I`m just waiting on a few pieces of hardware to make their way up to the great white north and by the time I have them I should be able to finish my testing. I will continue to update the forums with my progress. Thank you all for following along!

In the case that both need to be programmed together I`ll be happy to offer the viewers of this thread a 2 for 1 programming for their patience.

 

I too have a dokus programmed HMI so I`ll be able to tell without a shadow of a doubt if both units need to be programmed together or if we can program the radio independent from the HMI. Cheers!

Don’t recall if this has been mentioned, but I stumbled across this by accident. So the three obvious ways of summoning Siri do not work (home button, touch screen button, and steering wheel). I did discover by total accident tonight that “Hey, Siri” does work. I get the audible chime, but still no voice feedback. I can say “Hey, Siri give me directions to work” or “Play some metal” and it works, albeit a little slow. I will experiment some more tomorrow to try and determine how far that can work and what mic (phone or truck) is being used. 

 

Also adding to that, about a week ago, Siri turn by turn played through the sound system for one short trip. I got excited, but haven’t been able to duplicate that since, but it gives me hope. Today, it would lower the music volume at every turn, but no directions were audible.

I think I may have the solution to the no audio issue. It seems that Apple CarPlay has THREE volumes. One for Siri, one for Navigation and the other for music or maybe that was Phone. Let's start with Siri. Do something to make Siri reply to you. Try to make it something that will make her talk for awhile. WHILE she is talking, turn up the volume on the radio. It must be exactly when she is talking. If you don't get it just right, you will be changing the radio volume, not Siri. Another suggestion is to adjust the volume controls on your phone. In navigation try the same thing. I have also read that there is a setting in Apple Maps for audio. The settings if I remember are: No Volume, low, medium and loud. Someone else solved their issue by resetting the phone while connected to Carplay.

 

All this applies to Android Auto too.

 

The problems I have been reading in this thread are issues across the board with many other brands. It is issues with Carplay and Android Auto. NOT isolated to our trucks.

 

Do a web search about this and you will find pretty much the same. I used Siri no volume Carplay as my search terms. I don't have time right now to expound on this right now. Gotta run.

Well I installed my dokus HMI. No problems there. However the USB port that I purchased must not be compatible with AA. I have the projection icon, but when I plug in and turn on AA, I get nothing. At least it was only $20 for the port.

Woody, what was the part number of the usb connector you purchased. Also, do you have Android auto installed on your phone? You need to download it. A lot of people think it will just work when they plug it in like carplay does.

What trim is your 2015? Do you have a center console? What cable are you using, OEM, aftermarket cable? What kind of phone do you have?

 

Let's try to get this solved for you.

It is a LT. I have the jump seat console. That is the USB I replaced. I used an oem and an aftermarket cable. I have a Galaxy S7 edge. My phone worked with AA in my mother in law's Buick, so the only thing that I can think of is that I bought the wrong port. Or does the battery need to be disconnected and reconnected?

Your comment didn't go unnoticed! Just doing a bit of research on the subject, and while YES, AA and ACP do have different volumes based on the task at hand, the problem most certainly lies in the module not being compatible rather than there being a software issue. 

 

I ran some tests to check out the fixes in THIS THREAD that I found when I Googled the issue you suggested. 

 

Unfortunately none of them worked. Furthermore, to be more convinced it's the module and not the device, I can unplug my phone and plug it directly into another car that has AA and everything runs and plays fine, I'll unplug it and put it into my truck, and nothing. I tried adjusting the volume knob during a song, using the steering wheel paddle volume controls, Spotify volume controls, android volume. Nothing.

Looks like we need to hold out for the radio module programming.

Nope you have the proper receptacle.

 

2 things I can think of. First verify the time on your radio is correct. If it's not, Android Auto will give you an error. 

 

Second, if the LT without the console has a secondary USB plug (I'm unsure, I haven't worked on that model yet), try plugging the device into that. I was able to get AA to show up in projection at the very minimum using the stock USB plug. If there isn't another USB plug, try swapping back in your old USB plug and test. 

 

Some other things to try - Get an iphone and plug it in to see if carplay shows up. I'm sure you know someone with an iphone.

 

Also, is your phone charging when you plug it in. Does the aux input work? Can you play audio over a usb stick?

 

Keep us posted.

      Has anyone recently had issues with AndroidAuto not connected to their phone?  I've tried three different USB cables (all which charge the phone), reinstalled AA and removed all Bluetooth connections and reconnected the phone.  I suspect AA recently updated and now we are waiting on GM to update the infotainment system. When I touch AA on the screen it says, please connect a phone with AA app installed.  2019 Silverado RST with 8 inch infotainment, connecting a Samsung S8 with AA version 4.4.592344.  Yes, it had been working before, and one of the cables I tried was the one it previously functioned on.

      First time poster. Have a 19 Trail Boss LT and when connected to CarPlay get a notice that says “access to contacts limited” but I can see my contacts behind the notice.  Then randomly it will work and I have access to my contacts.  I have attached a picture of what I see. Anyone else experienced this?  I have used multiple cables and it occurs on different phones.

      See a lot of questions asked about this and not a lot of set info on the upgrade.  Hope this helps even anyone trying to set it up.
       
      **READ ALL INSTRUCTIONS AND WATCH ALL VIDEOS PRIOR TO ATTEMPTING PURCHASING OR INSTALLATION**
       
      Apple CarPlay / Android Auto functionality is not supported in any 2014-2015 (Many 2016) Silverado/Sierra’s. This is due to neither application being available from Google or Apple when these vehicles being built, therefore not an available option during these model years. The following instructions are designed to simplify the process as much as possible.
       
      Three things are required for this upgrade (ONE) Radio Module, (ONE) HMI Module, and (ONE) USB Hub 2016+.
       
      Search around for the modules, they are available for purchase from many different locations. EBay, totaled vehicles, junkyards, or other various websites to find them. AGAIN, if the part numbers are not listed below DO NOT purchase them.
       
       It is highly encouraged to not try and cut corners with purchasing part numbers of modules not listed as they cannot be flashed to work properly.
       
      **DISCONNECT THE BATTERY PRIOR TO INSTALLING FRESHLY UPDATED MODULES**
       
      TOOLS REQUIRED:
      Trim Removal tool
      10 mm Socket
      7 mm Socket
       
      PARTS REQUIRED
      USB HUB P/N 13519224 (BLACK) P/N 13509943 (WHITE)
       
      HMI Module
      USE ONE OF THE BELOW P/N’S IF YOUR TRUCK CAME FROM THE FACTORY WITH NAVIGATION. ONLY REQUIRED TO PURCHASE ONE P/N.

      Once acquiring the parts you can now send them to be flashed. These modules will be flashed to your VIN and will then be plug and play. Copy the link and follow the prompts.  
       
      http://www.whiteautoandmedia.com/index.php?page=shop.product_details&flypage=flypage.tpl&product_id=98&category_id=44&option=com_virtuemart&Itemid=54
       
      If you have followed all the directions up and to this point, select yes for hardware match. You can chose if you would like the maps updated on your NAV if you so choose. You will be emailed your order number from WAMS, this is EXTREMELY IMPORTANT. You will be required to ship your parts either FedEx or UPS, they will not accept packages from USPS. You will need to write your order number on the box to ensure your order is properly handled. Turn around is approximately one week from shipment to return. ONLY ship your (ONE) Radio Module and (ONE) HMI Module. Maintain your USB Hub.
       
      Once you have received your parts from WAMS you can begin installation. Disconnect your battery prior to installation.
       
      To install the radio module watch https://www.youtube.com/watch?v=I2MYuuyqLrs. For the purpose of this install start the video at 1:00. Stop the video at 2:04, the radio module is visible with a green connector on the far left. Simply begin disconnecting all of the connectors plugged into the module, once all are removed you can slide the module out of the dash. It is retained only by the tension of the cables plugged into it. Replace with your new module, you can now continue the video and finish putting the dash back together. Stop the video at 4:10.
       
      To install the HMI Module watch https://www.youtube.com/watch?v=sFe2gwlOsD4. Stop the video at 2:00. The module being described behind the crossbar is what you are replacing. Remove all connectors, the module is retained with a plastic clip on top. Installing the module along with the glove box, is self explanatory.
       
      Take note of the plastic tabs on the sides of the USB Hub you are preparing to install. Those tabs can be depressed with a dental pick and gradually removed out of place. Once removed, disconnect the harness and reconnect. Installation is now complete. You can now reconnect your battery and start your vehicle. Initial start up might take a few seconds to initialize, and temperature defaulting to 32 degrees is normal. Android Auto and Apple CarPlay require hardwire connection, so to test functionality it needs to be connected to the newly installed USB hub.    
       
      MVI Inc (https://www.gm-navigation.com/) offers kits and other customization options if the above is not something you feel comfortable acquiring on your own.
       
      Hope this helps, should be pretty cut and dry. There might be other methods, but this was the cheapest I discovered. If you have any questions don’t hesitate to ask.

      Hey, everyone!  New to the forums here -- my name is Chris and I just picked up my 1st Suburban yesterday; a CPO 2016 LT w/Luxury package, Sun & Entertainment, wheel upgrade, etc.  Loving the truck so far, just one minor issue.  I am unable to get the car to recognize my Pixel 3 XL and launch Android Auto.  Before anyone asks, yes -- I have the AA app installed.  I've done my due diligence before posting, scouring the web for hours now, to no avail.  The USB works in charging my phone, but the car just won't launch AA.  I was able to connect my wife's iPhone and CarPlay launched immediately.  I tried a couple different cables and even tried all the "developer options" tweaks that I read about online.  I ordered a couple of different USB-A to USB-C cables built to 3.0 spec just to be sure cables aren't the issue, but other than that not sure what I can do other than waste 1/2 at the dealer to see if they can figure it out.  I really don't want to have to do that.  Help, GM-TRUCKS.com, you're my only hope!

      Alright... let me take a deep breath...
      I just bought a 2019 Chevy Silverado Custom Trail Boss.
      I am having an issue with my 2019 Chevy MyLink infotainment system and its integration with my Note 9 since the Android Pie update.
      The issue: When I receive a phone call through Bluetooth OR Android auto, I am able to answer the phone call but... The ringer will NOT stop ringing on my infotainment system. The only way I can talk to the person on the other line is by picking up my phone and disabling it from the infotainment system (this did not happen at all on the previous software version and it was glorious). The ringer will also never turn off even after the phone call is ended. The only way I can turn the ringer off while driving is by turning it down (cannot switch back to radio to continue listening to music, which is very aggravating), so I am sitting in silence for the remainder of my trip... unless... I pull over on the side of the road, shut my vehicle down for 2 minutes to let the computer reset and start it back up. This issue does not occur on my work iPhone either...  I thought that it might be an issue that chevy's infotainment support team could solve... It seems that it is not their issue because it only happens to android Pie software version phones and not any others. I call Samsung... do everything you could think of to troubleshoot this issue (finally factory reset my phone completely only to NOT resolve the issue). Samsung seems to believe that I need to send my phone in for a repair (even though it wasn't happening with the previous software version). Chevy thinks I need to just wait for a new software update for Android Pie... but I hate waiting because it is a very aggravating issue and love my music! Is ANYONE else having these same issues? Is there a solution that anyone can think of? I would like to just revert back to the previous software version and forget about it, but I am not sure of the problems that may cause...
