Help w/ Pandora

2014XI with Nav/I-drive. I stream music from Pandora and from the 1600 songs on my phones internal storage. The songs on my phone work perfectly and the the info (artist, song title) shows up on my I-drive screen and I can control previous and next track with the I-drive controller. When I use Pandora it streams flawlessly and I can control next track, however all that shows on the I-drive screen is "UNKNOWN ARTIST". Any ideas as to why and how to correct the problem?



Thanks in advance
