My car, a Land Crusier 200 has a grill/mesh panel above the navigator on the dashboard. It pops out with a bit of force. I bought a spare one for about $60 from Toyota and am mounting the touring stuff to that - HF radio head, phone mount, and VHF / UHF ham radio head etc. Plenty of space for more. Everything has a connector so it can be removed when I'm not going away and it can all go back to standard with nothing in the way of the windscreen etc and nothing to show. It takes about 2 mins to swap over.
