Lets face it the Sat Nav is a modern must have (even though it not needed to go to work everyday - like some use it). Most car makers, for some reason, feel that they have to sell the display with the car, and to assist them doing that they make it difficult to put your sucker pad where the lead supplied will reach and the unit will still be within reach. The dash having no flat srfcaes to attach a plate The Citroen range with its big screens that are far away make this difficult.
On my C3 I fitted a small round mirror in the tray above the radio and stuck the Garmin unit in there, it worked well.
On the C4 pic I had to put my Navman unit on the side window, however the other half didn't like that as she couldn't see it. Lead was just long enough.
On C3Pic the lead again only just allows the unit to be on the side screen. But can't put a mirror in the tray as unit is bigger and the gear knob obscures it.
So whats the fix. Well there are small heavy bean bag devices http://compare.ebay....type=pla&crdt=0 that sit on the dash top and hold the sat nav available, this way it's withingreach of the power and the other front seat occupant can see it. Xsara Pics have a reflective screen and some sat navs don't pick up the signals very well through them. It's time that car makers put a power socket on the dash top.
