### 1/5 — Trash

*2024-10-13*

Doesn’t even have any of the popular music streaming services like Spotify or Pandora. Just Apple Music and some weird Asian knockoffs. Trust the low reviews and don’t get this waste of an app or of the device.

### 5/5 — Awesome

*2021-03-30*

Love the find my car feature
