Hi all, this question might have been asked elsewhere but I searched and couldn't find an answer. Just bought a new 2021 GLC-300. Love it! I have over 2000 songs on my iPhone. I've connected my iPhone through bluetooth and it works fine. Except, if I want to play a specific song from my song library, I cannot find a way to do it. My last several vehicles have been Jeeps with Uconnect. To play the song Happy Birthday from my huge playlist, I would simply hit the voice command button and say "Play song Happy Birthday." With voice and all the buttons in the Mercedes, I cannot find a way to easily find a song and play it. Help! Thanks to all.....
