Made a custom mount for my Garmin nuvi 6". Made it out of kydex.. Heated, molded to fit.
Removed the head unit to hide the wires, installed a 12v socket near internal fuse box.
I have the factory nav. But it sucks and I'll be damned if I pay $400 to update it. My Garmin has lifetime map updates AND my backroads map book offroad maps on it too.
Mount is. 08 kydex heated to 400 degrees and molded to GPS and mount location.
Not a professional job but I'm happy!!! GPS is removable (Velcro inside mount to hold GPS firm). I don't miss the clock. Just added clock to my Garmin screen. Nothing permant... Very stable.
LOVE the location!!!!!
