Finally got a nice GPS installed into the Z today. Garmin Nuvi 3597LMTHD mounted in the cubby with a modified Nuvi ball bracket and a custom friction hinge. Hardwired it behind the dash leaving ZERO wires to be seen
I splurged on this model but, it was well worth it for the features and HD traffic updates.
It looks as if the GPS is shoved in there but, it actually doesn't touch the sides at all. About 1/4' gap all around and the mount holds it firmly when touching it. Sorry for the iPhone pics :/
