I have a Proclip mount for a Garmin GPS unit that mounts to the right of my radio. There are threads elsewhere on the forum. You can get one for the IPhone.
Here's a link to what I have. You'd just have to get the right 'ball'.

I also run a Garmin vent clip to hold an LG smartphone that communicates by BT to a Valentine 1 detector. I run an app called YAV1 on the LG for the V1.
You can simply Google 'Garmin vent clip'. I modified it a bit with a file to 'clean up' the fit a little better. I originally wanted to put the GPS on the vent clip but I thought the unit was too heavy and I figured the vent clip would mess up the edge of the vent bouncing around. The way I have it I can also mount the LG to the Proclip mount. I have a 'Garmin' ball on the Proclip mount.
Does your OBD use bluetooth to communicate with your IPhone?
If so, I suppose I could run DashCommand on the LG too.
