Changed to 1 star...though the permissions allow location when using the app (selected) crash errors and permission requests for "allow all the time" persist even hindering app use due to a full screen "nag". When "allow all the time" is selected the app still doesn't run silently as a service (as previously did the 'Entune' app), however battery drain is high because the app wants to know where 'it' is even when the car is sleeping in the garage. Very poor developement, not worthy of Toyota!
