It just goes into your CD deck on your stereo, expands a clamp, and can solidly mount a phone!

Knowing the make and model or a pick of the dash would help. In the car I use a CD player mount, like this , works best. I’ve also thought about getting this for an older car I have incase I need to use it.

Sorry, just saw this. It's a cheap amazon CD phone mount lol I got it here.
