Before I moved my camera and put tinfoil inside the weatherproof box/mount, it totally screwed with my GPS. But I've never had a problem that I can remember with the wireless sensors and computers. It's all Blue tooth now though and smart phone unless I'm geocaching, then I mount the Garmin Montana on opposite side of smart phone from camera. The GPS in the smart phone is good and will get you in the vicinity, but the Garmin gets you right on the money.
