FWIW, I have reached a frustration level with the Carlinkit Wireless Adaptor which functions properly about 60% of the time. The balance of the time it freezes and requires you to open your settings and manually make the connection. I just purchased a new Truck and ordered a different Adaptor (Motorola MA1) which is working like it should. After installing the Adaptor in the Ram and seeing it function properly, I ordered another one for the GLC and I'm happy to report no more freezing! The Motorola MA1 paired and worked on the first try without any issues.
