Sometimes the radio doesn't display song info on Bluetooth? (2015 CR-V EX)
I generally connect my iPhone to my CR-V via Bluetooth, with Spotify being my default music app (although this also happens with Apple Music so it's not the music app). Sometimes I see the song title, artist, and album, other times those fields on the display are blank. No matter what, my car plays the music from my phone just fine, it's just a minor annoyance that I can't always see the song info on my display. I should also add that this has occurred with multiple phones (my previous iPhone SE and my current iPhone XR), so I don't think it's a phone-specific issue.
