Hello all, I recently got an OTOCAM3 on E Bay, how hard are they to install in a 2012 TCH, is it a plug and play install? I know some others have done it, any one care to let me know what is involved? I have a few questions like; Is it just a plug and play without much wire splicing? Where do I mount the GPS antenna? Should I splice the backup camera to the reverse light circuit or to the otocam3 itself? And what is all the talk about the parking brake ground and playing DVD's? Thanks!
