Thanks again NebOd - I've added the security brackets to the Connects2 cage and the fit is very neat. I have a Pioneer AVH-X5600BT unit and have connected it to my old iPhone 5 via the VGA adaptor. Whilst I'm impressed with the far better sound quality of the Pioneer HU, I'm not that impressed by the 800x480 screen and also find it very hard to see the screen on a sunny day with the roof down. I haven't tried an anti-glare cover yet. I think like many other comments on the web, there is so much more to come with smartphone integration into HU's, and at the moment it's very far from perfect.
