Since I have BodyGuardz on my Touch Pro, I never wanted to try using a ProClip Touch Pro holder with my ProClip dash mount. Since
it was already mentioned, that the ProClip holder could cause the BodyGuardz to rub off on the sides. I had been using
an IGrip knockoff, that can hold the Touch Pro in portrait or landscape and someone showed how it looks in landscape
in this prior comment. But not having that nice ProClip car mount in use was just getting to me. So I figured out a way to use the ProClip mount in combination with the
IGrip type holder.
I still had the ProClip device holder from my old Treo 800w. I sawed off the sides of it, so just the flat portion remained.
(I used an MXZ saw, but I guess any common hack saw will do the job.) This gave me a flat backing to use with the old ProClip swivel attachment. Then I took the
IGrip knockoff's back piece that would normally be used for vent mounting, removed the vent mount tab from it and used some
MightyPutty, to attach it to the ProClip. From there, simply attach the
IGrip knockoff's holder piece to what used to be it's back for vent mounting and it's done. A custom ProClip, that can hold the Touch Pro in portrait or landscape and has full swivel functionality.
I've attached pictures.
I might use some black paint to have the MightyPutty blend in a bit, but this makes me happy for now
