This is an odd piece of kit as it's furry, yes furry, so the iPhone slides right in and even if you miss first time, you're not going to scratch it.
It's fitted using the Brodit car adapter, Brodit sell non damaging adapters for most cars, and as my car is brand new I didn't want to drill any holes in the dashboard.
So it's sits just above the left air vent and I can see my maps and play my music whilst driving (safely, of course).
When using the GPS I can safely turn it sideways to get a better view.
The only drawback is that I have to remove it from the case, but for me, that was the plan.
(Brodit also do a holder that you can use with a case)
