I have a 2011 Laramie that previously had the RBZ Media Radio. This morning I upgraded to the 430N radio with Garmin navigation. I checked out all functions of the new radio and everything is working perfectly except one thing. The GPS will not show my current vehicle speed. It isn't displaying on either the map screen or the speed/dashboard screen. See photo below. It's the current speed in large circle that is not working, no matter how fast I am going it always says "0". All other information is updating, mileage, bearing, elevation, even my max speed is showing correctly and goes up as I speed up. Navigation is working fine as well, even estimated arrive time.
Any suggestions on why? I don't suppose I need a sales code for the 430N added to the truck? Has anyone else upgraded to the 430N and did you have this issue? Also if it matters I also have a lockpick Gen 4 installed as well.
