* Note in the video I repeatedly use the term CarPlay or Auto CarPlay to refer to both Andriod Auto and Apple CarPlay. This video may apply to all current cars that utilized either Andriod Auto or Apple CarPlay to allow Android and iPhones to provide the drivers with navigation and infotainment features.

If you find you can't use many apps like Waze or your Auto/ CarPlay screen is low res then this video will help you.

Vehicle: 2021 GLB250 MBUX with wired Auto/CarPlay
Phone: 2019 Samsung Galaxy S10 plus

Issue: our 2020 Test Drive GLB had Waze Navigation and a 1080p Wide Auto/CarPlay screen. The 2021 GLB did not have these amenities. The Dealership was no help since Auto/CarPlay software is not something they service or monitor.

Solution: After searching for two weeks on the web I found a single paragraph at the bottom of a Auto/CarPlay related page that vaguely mentions unlocking the App into a Developer Mode to allow "unknown sources" meaning any app you want will show on your Auto/CarPlay. There is also lots other Easter eggs to play with but for us upgrading the standard boxy 720p res to 1080p was a delight especially since to latest MBUX letter box screens over so much real estate!
