I have the Pro Clip system too in my Golf. It fits neatly and securely into the vent and is up close enough to let me use the Storm for maps. The Storm holder part can be rotated either way and allows access for charging.
I've been seriously considering Pro-Clip - I love the professional look. But I have the Seidio case - is there enough room to fit the phone in the Storm holder with a hard case? I might go with Pro-Clip but get one of the adjustable mounts to give me enough width. I definitely don't want to have to take off the Innocase all the time. (I already have a Storm cradle not getting any use because of the case)
Thanks again to Lowsol94 for the ideas and suggestions. Wanted to let everyone know that I found something on eBay that suits my Storm car mount needs nicely:
