EV2

2008 Silverado with great FM and very poor AM reception. Does the antenna wire apply here?

Awesome mod, chrisbulla, thanks. Obviously, for safety reasons, the passenger can safely operate the GPS, etc., for the safety oriented driver. So, when 'another driver' has possession of the vehicle, is it safe to assume that an obscurely located on-off switch on the yellow/black ground mod wire would disable the feature and resume the 'factory' operation?
