Rehinwater

I thought someone from Ford monitored this site, and was hoping for a response from them.

Nothing has changed in the vehicle since purchase. Have definitely had hotter temps than this with no issues. Yesterday after I removed the Nav Card and held it in front of the AC vent for a few seconds, the error was gone once I re-inserted it.

I have a 2016 F250. When it gets hot outside, I get an error code telling me to Insert Nav Card. Once the truck cools down the error goes away, but once summer gets here it will happen more often. Any advice?
