That is correct, the album covers will only update when car is stopped on park. Not 100% on updating only on brakes though.I think its related to being stopped or driving. While stopped ( I cannot remember if required to be in park or just fully stopped via the brakes) the image will appear and when driving the image will be replaced with the basic logo. I have heard opinions that this is to not distract drivers. I think its too much micro management if that is the case.
