I have a Samy S4 on 5.0.1, but this issue seams to run the gambit of phones makes and OS's. I am in the market for an Android Auto enabled radio/head unit. Before I buy one, I thought I would try out Android Auto on my phone as it is supposed to work directly on the phone now. When I try to open AA, I get the error message "Something went wrong. Google Play services doesn't seem to be working now" There are fixes on the interwebs for folks that have a head unit, however I do not have one yet. I have tried uninstalling and installing AA, clearing cache on both AA and GP services. Nothing helped One fix I read said to uninstall GP services updates, and then let them auto update. However, the "Uninstall Updates" button is grayed out for me. Any help for a different fix, or help with a method to uninstall GP services updates?
