You're not missing much. I've used it a minimal # of times in the over 4 years I've had '13 Leaf SV with premium. On my '13s, you need to be connected to the car's USB port, as well, which I almost never am.
If I want Pandora, I just run the Pandora app on my phone. I'm connected via A2DP music streaming over Bluetooth.
'19 Bolt Premier
'13 Leaf SV w/premium package (owned)
'13 Leaf SV w/QC + LED & premium packages (lease over, car returned)
Please don't PM me with Leaf questions. Just post in the topic that seems most appropriate.
