My 2017 Subaru is obnoxious. The Bluetooth audio has a 2-3 second delay, way more than any other Bluetooth device I've ever used. My head unit has the same bug that plays Sirius preview channel. It used to happen all the time but I think what helped was setting all the presents. It would be nice to be able to update the Gracenote database since it's very out of date, I know Bluetooth didn't support album art until AVRCP 1.6 which came out later.

I'm considering swapping out the headunit but there are a few car settings the OEM headunit controls that I'm not sure if I want to relinquish control over.
