    I have recently change from a Huawei P9 to a OnePlus 6. My Kenwood car audio system worked fine with the Huawei but I can't seem to get the OnePlus to do voice dialling (when connected with bluetooth) unless I have a data connection (as it wants to use the online Google Assistant). The Huawei was using Android 7 whilst the OnePlus is using Android 9.

    I have tried clearing bluetooth settings, unpairing & repairing bluetooth.

    Am I missing something? Does Android 9 only use Google Assistant with an online connection? If I use the audio unit to select a number and dial, the OnePlus connects and works fine - it's just the handsfree voice dialling bit that doesn't work.
