In-dash navigation system (GPS)

"every time the truck was started the GPS SD Card acted like it was the very first time the truck had ever been used, and forced me to click a message saying something like "once this SD card is used in this truck, it can never be used again in another vehicle". Then when you shut the engine off and restart the truck, the same message would show back up again. It took two visits to the deal's repair shop, and a week of downtime for them to solve the problem"
