Bluetooth problems with Truck

So I have a weird thing going on with my iPhone 5s and Toyota Tacoma bluetooth audio....

I recently deleted a bunch of songs off my iPhone but can't seem to get them off my audio system in my truck. What I did was the following:

1. Delete the phone from the Bluetooth registration entirely on the dashboard (so no phones are registered)
2. Deleted the "CAR MULTIMEDIA" "device" off my iPhone itself
3. Turned the phone off entirely and rebooted it
4. Paired the phone back up with my audio system in my truck

I still am seeing Artists/Songs on there that are not on my phone. It's the weirdest thing. What's even weirder is some of them even play still..(where is it coming from??) And some of them say "NO DATA"

Any ideas how to get my phone and my audio system in sync and matching correctly?

Thanks
