This is a very simple smartphone holder for the Mercedes W639 Viano / Vito.
It's designed for Samsung Galaxy S5 with S-View Cover and the original SAP V3/V4 bluetooth cradle.
Advantages:
- zero installation effort, no tools required, no drilling,...
- the smartphone covers the annoying bright LED on the cradle
- use the cradle's USB port for charging the smartphone
Installation:
- put the 3 pins into the original holder's 3 whole
- attach the cradle to the connector (the cradle keeps the holder in place)
- open the S-View cover and fold it to the phone's back
- put your phone into the holder
Future idea: integrate Qi charger into the holder (not sure if the cradle provides enough current)
