Hi @rogers1026! Thanks for posting.
Since you need a mobile device to run Pandora in your vehicle, it may not be the Pioneer. I'd like to try some troubleshooting steps for your Galaxy to see if it will help.
From your Android Settings, please try clearing the Pandora app data using the following steps (not to worry, we'll keep track of your profile and collection for you):*
Open your device Settings
Tap Apps
Scroll down to find Pandora
Select Storage
On the storage details page tap Clear Data.
Keep in mind that the steps for each Android device is slightly different. You will be asked to log into your account after completing these steps.
Let me know if you have trouble signing back in.
