I don't know what you mean by "integrated" but this is my setup and I love having my hand free.
universal holder +
any car charger.
the universal holder come with a clip that you can use on your vent. i didn't read the instruction on how to insert it and broke a clip...oh well, the suction cup works really well though. another plus on the holder is that gap under the phone for your charger, therefor it doesn't get in the way and pushes the bottom forward.
