Fiat Ducato 2013 vintage - so the dashboard clipboard doesn’t stand up because of the electrics for the passenger airbag (not my excuse, but wot I wos told). The clipboard surface is not smooth, so the suction cup on the SatNav won’t hold. I use the clip thingy to hold the foot but it always works loose - and it means the screen is half a mile away. How do other Funsters fix their SatNav?
