Re: DIY: All NAV Functions All The Time without Firmware Downgrade!
For my personal SPG device I have the switch mounted in a special project box along with 6 other switches, a few chips, resistors, and some other special stuff. This is part of a major wiring mod that I did to add a lot of other options. I mounted this switch box on the front wall of the center console. It is out of the way and invisible to most people yet easy to reach when I need it and it doesn't take any space out of the console. The first two pics show it with the top console file bracket removed so you can get a better look at it. It works fine with the bracket installed and the bracket actually protects me from bumping the switches while taking things in and out of the console.
I did use some illuminated rocker switches in my dash for my train horn mod - see the third pic. The first switch toggles between factory horn or train horn and the second switch supplies power to a fuse box that I installed in the bed to run the compressor for the train horn, an AC inverter, and several other things. These toggle switches were initially too bright so I added some resistors to drop them down to match the other dash lights, then I hooked them up to the adjustable light dimmer control so they come on and off with all the other interior lights automatically.
