Didn't your Lariat come standard with GPS? If so, why do you feel the need to have two GPS?I recently purchased this great product from Proclip that solves the problem of where to mount my GPS. This clip secures to the dash without any adhesive or drilling any holes. It could be used to mount almost anything.
Android? You should be able to do the same...I don't use an iphone.
You could have used Android AutoI'm curious why you didn't choose to run Carplay from your phone's GPS and display to dash monitor?
