Purchased Daughter 2014 IS 250 and car is great with exception of connecting her phone to audio. Posted separate thread on USB but have bluetooth issues as well. Have connected her iPhone 10, my iPhone 6, my current generation iPod mini and all connect via bluetooth with regard to connecting and being able to manage the device from the cars controls. Just the audio does not play right away. By right away I know everything has t time in but it can go 4-5 minutes before audio plays through the car. Have erased both car and phone and reloaded and same results. Any suggestions?
Any help would be appreciated. Thank you
