This is a discreet holder for mobile phone it is designed to be fixed on the stock multimedia display of the car.
I used a 3M dual sided red tape, it is made of plastic and can be removed without mark when needed.
Once the holder is in place, I used a magnetic holder that you can find by amazon for a few bucks.
The holder I used is https://amzn.com/B00Z9ZXZQC ( Nochoice® Crazy Mount Magnetic Car Phone Holder for iPhone se 6s Plus 6s 5s 5c Samsung Galaxy S7 Edge S6 S5 Note 5 4 ( 42mm Black) )
I use it all the day and works pretty flawless with my iPhone 7 Plus.
Please put comments if you need some modifications.
