Get this message a lot. Finally took it in. Bad SD card - $321.97. I don't use the truck'* GPS, so not replacing it. Wonder if I can get them to turn off the message or maybe I can make a copy of someone else'* card. Anyone know or have experience with this problem.

Buy another card. Should format automatically when installed.
Don't get any larger (more memory) than what'* in it.

On another forum, someone gave me this link. $149 versus $321

Cool!

I'm curious if that works out well for you. It would be good for others to know.

I found one on Amazon for $42, so I have ordered it. Should have it Sunday.

Tried it and the truck does not recognize it, so sending it back to Amazonl

Do you have a format option?

Nope. It just says that the card had been removed - with an error code - which is a different message from when then original card is in. I don't think the original card is damaged if I can use the NAV with no issue.

Card reader may be bad.

The dealer said the reader was bad. So I am not going to worry about it until I get the other items taken care of. just annoying right now, the days that it pops up. Not every day.
