I've used both versions of the ProClip for the Ody. My first one was the center-mounted one, which I didn't like. The second was the left-hand side version, and IMHO it's much better.
Let's start with the "pros":
They are both, I believe, best-of-the pack when it comes to holding your phone.
They are expensive, but then they're custom-made and look good.
The center version won't block the airflow from the center vent.
Now the "cons":
Both versions rely on a doubtful piece of thinking: the idea that small, strong adhesive pads will keep the device in place and stop it moving. They won't.
Left-side version does block the side-vent a little.
Center version:
The center version is the worse of the two in this respect. It mounts using a long, broad "strut" at the back that clips into the bottom of the plastic screen on your central display unit. The other end of the clip is secured using an adhesive pad into the top part of the left center vent. There are two problems with this arrangement. The first is that the adhesive pad is being used to some extent to prevent downward motion of the clip. In other words, that pad is the only thing that stops your clip, your holder, and the weight of your phone pushing the front of the clip downwards from its mounting at the top of the vent. Secondly, that adhesive is also used to stop your clip rocking in the horizontal plane. With regard to both these problems, the adhesive weakens. The clip can't drop out, but it will fail to hold the clip steady in the horizontal position and it will start to "lean" a little in one direction.
When I decided I'd had enough of it, I attempted to remove it. It proved impossible to release the back part of the clip from the bottom of the central display unit, and it broke off. Happily, it was the clip that broke, not the plastic screen.
I have no pix because I don't have it any more.
Left-side version:
Easily the better of the two. The clip mounts on the rear of the driver's-side quarterlight - a clever piece of work. However, the clip would be free to move up and down in its secured position, so there is - you guessed it - an adhesive pad inside the mount to stop that happening. After a while, the stickum weakens and the clip can slide up and down about an inch or so (mainly down, of course). However, the design grips the mount position so well that this only happens slowly, and all you have to do is to reach out occasionally and shove it back up.
If you have floormats or something similar, you don't have to worry about running the USB cable across your dashboard. Instead, get a long cable (about 6' or better), run it downwards from the 12-volt outlet, under the carpet, and then up inside the rubber seal around the front of the door opening. You need only lift this a little and the cable will run inside it. It emerges just about window-level, right next to your ProClip holder.
I've attached a couple of pix which I hope will illustrate what I've said.
By the way, I don't want you to think that the holder in the pic is the sort of thing you get from ProClip. It's a hacked version of one: my original phone was small, and the ProClip holder for it wouldn't accommodate my gigantic new phone, so what you see is a Frankenclip created by me.
