I have an iPhone 6 and a 2015 Subaru Outback. When I connect my iPhone via USB to the system my iPhone cannot detect my cars speed via apps (Waze or any other speedometer app). But when I disconnect and play music/podcasts over Bluetooth it works fine. What is up? My iPhone is jailbroken but does not work in No Substrate mode either.
Got a tip for us?
