Hello, I have a 2015 Silverado That did not come with the apple carplay / android auto option until late 2016. So the fix is to get an HMI module, Radio module & USB hub from a 2016 or later GM vehicle. which is exactly what I did. I got everything from a 2017 Silverado truck. The problem is since the modules came from a junkyard, they have a different VIN than my truck. The radio will theftlock and the HMI module will not work. So the solution is to clear/re-write the VIN into these modules from my truck. I have been on the internet looking everywhere for a solution, I even called the Delco TDS tech support line. They told me since everything is now "Global A", GM does not have anything to reprogram used modules. SPS2, GDS, etc. all will not reprogram GM modules. GM has in in house programming software called Developmental Programming Software or DPS. with this you can do just about anything to any global A gm module, Radio, HMI, ABS, SRS, Instrument cluster, Power steering module, etc. There are 3rd party hackers that sell this on the internet with a "key" or license. But they are not clear on how long the license lasts, etc. Once you have the DPS software, then you need to purchase a file that will re-program the vin, which is anywhere from $60 to over $100. I went on one of these sites (cameraloops.com) and registered in their forum and inquired about what I needed & the costs. The next thing I know is all my posts disappeared. and when the next time i tried to log in it said BANNED across my screen. I received no communication prior or after. I dont know if it was a scam site, or it was shut down by the internet police or what. There are companies that you can send your modules to and they will program them for you; MVI, White Automotive / WAMS, etc. But they want $100's to reprogram modules. Does anyone know of a scan tool, software, etc that is capable of reprogramming gm modules other than ECM's TCM's, which my HPtuner does. If HPtuners could develop a tool to reprogram used modules they would be rich beyond their wildest dreams. All of the millions of used modules in junkyards are just going to waste.
