When zlink/Apple Car play is not activated, the steering wheel phone buttons on my Honda Accord can control the iphone via Dasaita bluetooth radio (NOT USING HONDA OEM BLUETOOTH RADIO). However, when I connect zlink/Apple Car Play, that feature does not work. Seems there is a bug in either the Dasaita firmware or zlink app.
Phone buttons on steering wheel should be supported via Apple Car Play (it works that way on my Toyota w/o Dasaita) so I think it is not an Apple Car Play issue.
I want to be clear, that I physically disconnected the Honda OEM bluetooth radio, and the steering wheel buttons are connected to Dasaita directly.
