To find out what options are available from Broit to fit the Volvo V50 click
Here and scroll down a bit to where it shows the dash pictures and where the various clips go in the car.
In my V70 I have three Brodit clips:
1/ iPhone powered holder low down to the left of the stereo
2/ Garmin 3790T center top air vent (This picture shows the Go-940 Live in the same place now occupied by the Garmin).
3/ TomTom Go-1000 right air vent (This picture shows an XL IQ Live fitted where the Go-1000 is now located).
All three are really solid with no issue of the device falling off and it puts the units in a nice and easy to reach position. If/ when you change the nav unit/ mobile phone you simply change the holder that is specific to the device, the Pro-Clip can remain in the vehicle as they are generic - Mike
