I'm working on kitting-out an '07 FJ and I need some advice on GPSs. What are the best systems to put in the dash compartment on the driver's side? I'd like a system that has good data and maps for trail use. I'd also like something that won't blind me at night. Last thing -anyone know whether it's too difficult to hard wire it so I won't have a power cable dangling out of the cigarette lighter? Thanks.
