EDIT: The only reason why I still had it at this point was because I could use it with other apps. However, now that my Spotify Subscription is cancelled, it doesn't work with anything. It's mildly infuriating because today, I can't still use it with other apps like I was able to yesterday.
Please don't make the same mistake I made. No one should buy this.
Or for $5 you can use Velcro strips to stick your phone to something in your car, or for $0 you can just balance the phone on your dashboard.
The cheap tablet or phone mount works well, but a nice radio is a lot cleaner and IMO is worth the expense.
