Too bad there's not a separate fuse/relay for the WiFi only ... but as stated by Merc6, the MyChevy app is supposed to allow you to disable the feature, yet I'm not aware as to whether or not it would actually stop the signal from being broadcast. Maybe I'll test it out on my Camaro and see if the signal is gone. I feel your pain, as I don't have any WiFi plan in my Camaro right now, but every time I'm in the car waiting for kids to get out of school, it tries to connect to the car's WiFi ... so I always have to turn off the WiFi on my phone so it doesn't try to connect to it. I'll try this test on Monday and let you know if it works!
