Hi, yes the hole in the head. There is a plastic press in cover, very careful not to damage the edge and you can pop it out. I used my finger nails, as my finger nails will grow back, the replacement plastic bung will cost money to replace
I don't have any pictures on my pc, and at the moment I do not have it installed as it is too cold to ride for me. I only use it for touring really, or camera use.
I will try to take some pictures tomorrow (uk), with the SatNav in place and the camera. There is a difference as to use the RAM system you need to have a ball installed, use different length RAM arms, different attachments for whatever you want it to hold. Sounds confusing, but it makes sense when you see it. It works very well, but the cost can add up.
I bought it to tour from North Wales to the south coast of Spain, where my dad lives. He is a biker too, he has a Yamaha R1 '07. The RAM was faultless, hold whatever you attach in a rock solid position that you do not have to correct or adjust unless you want to. If you want to all you have to do is, loosen the giant wing nut, move into position, tighten the wing nut. If you leave the wing nut at the right tension, you can move things without adjusting.
