21AT43.0

Hello everyone! Well after being with MOPAR for 12 yrs or so I decided once they dropped the ecodiesel to give GMC another shot with my AT4 3.0. I’m really disappointed in the lack of aftermarket support and customization options. Is there any upgrade options for the stock LED headlights at all? I feel like they lack in brightness, I am coming from HIDs that I retrofitted myself. Also the aftermarket stereo department is also dead since I have the 8” screen I guess without the Bose system…. If anyone can help or point me in the right direction that would be amazing. One last thing I used an app called AlphaOBD which was amazing I could do anything to my truck a dealership could, do we have anything like that for the GM trucks?? Hoping if not it’s coming soon.
