Anyone got a Garmin 65 and an iPhone? Not showing album art.

[SistersofPercy]

Just put a Garmin 65 in my car as a replacement screen for the manufacturers old, clunky map system (older car). When I try and play music through it via bluetooth with my iPhone it plays but the display wont show me the album art. Tried it through the husbands S10 and it shows it.
Have updated both Garmin and Phone and still got nothing.
Any ideas? Or just a case of not compatible?
