What I use is the Uniden bracket (it snaps into it) and some Ram mounts.
I have the Ram ball bolted to the side of the center console and 2 arms and a ball to get it where I want.
There are unlimited options using Ram to get where you need. Should be able to do it all for under 50-75 bucks.
I also hardwired in power with a tiny toggle;e switch. I turn the HP on and off on the unit - but can turn the power adapter o/off separately.
I usually leave on when in and out of the car - I'll just press menu and it pauses, if needed. I do turn off when parked at home.
I use a HP1 - but have a 2 if I ever get to a PH2 area (also have some usb outlets avavilable). It's worked fine since the HP1 first came out.
