Did the vehicle originally come with the HMI 2.5 module? If so, program the HMI using the GM SPS service.
I've got a 2015 Silverado VIN # 1GCVKREC1FZ362916 attempting to update to HMI 2.5. DPS shows complete but only thing different is it added the weather app. Still no Apple Carplay or Android Auto. Any help is appreciated
Works 100%, full access
Yes as @LLCasaol said. Purchase first then you will know the secret. I will be raising the price soon.
