KMD, spm0912 - be interested to hear how you get on. I'm using Android Auto, not CarPlay.
I too cannot get sound via the speakers, set a frequency on both the unit and the radio, enabled the transmit button, but sound still out of unit, not radio. Even disabled speaker in unit settings.
I also have a conflict with the old Parrot car handsfree - they both answer but the unit wins and although the Parrot displays the call, it does not handle the audio.
I have the unit next to a Garmin satnav. Something seems to interfere with that, I assume from the new screen. Garmin cannot find satellites, or weak signal warnings. Odd as new unit has no GPS. May be RF interference from poorly screened unit. I'll try moving them apart.
