I remember seeing electronic stuff in this type of thread so I hope I'm okay with this. I figure it can get you to a trailhead so it's remotely camping related.
I have a Tom Tom One that I have used a handful of times and would be interested in trading it off for something. I am in need off underquiltage. I live in Florida, so it doesn't have to be anything super special.
Top quilts, cook kits, pointy things, water purification (perhaps a DIY gravity deally), etc.
May be a shot in the dark, but ya never know.
