I have seen chaps put it in the ashtray which is a good place, or run it to the cupholders by the hand-break. Usually you need to do a little drilling. I put mine in the glovebox cause I didnt want to drill the car. The glovebox closes fine with it coming out the back, and run it under the trim along the transmission tunnel and beside the passenger seat, always there when you need it and when you want the car neat just tuck it away.

You will need to remove the headunit, aircon and trim around the transmission lever. The clips on these bit are not brittle and its a super easy job. If you have the double din nav unit, its a flippin mare to get out the first time, with its fiddly little push in both sides at the same time system.

Depends where you keep your phone I suppose. Glovebox is a 30 second job the others are not.
