Be extra careful that you have input and output devices correctly identified or you will wipe out the good card by writing the bad card to the good card.

if - is the input block device
of - is the output block device
bs - is the block size (in this case 100 MB)
conv - is the conversion to apply to the copy

# dd if=/dev/sda of=/dev/sdb bs=100M conv=notrunc

Oh, and the # prompt means that you will have su'd to root or sudo'd the command. If you don't know what this means and are not comfortable with it, then don't try this and use another solution.

Review the dd man page for options available to you and be careful with commands like this - they can be catastrophic. You have been warned multiple times!

You probably should have used this method to make a backup of your OEM card prior to attempting any modifications. Just sayin...
You have 2 SD card readers? one inetrnal, one external?

Hey I donít remember paying extra for nav at the dealer, I donít have the sat radio subscription.

So is the nav something I would have had to add or turn on at the dealer?

Does it actually work when you are way out in the boondocks?

Doing a straight clone of the sd card to another card wont work even if it is a bit by bit duplicate because of the encryption on the file linking the maps to the specific card. There is a unique file that is encrypted with the hardware ID of your specific card. If you clone the card the encrypted key for the prior card will copy, when the system checks to verify it will see your card is a different card than the original and will fail to load. The only way this would work is if you were backing up your own card and flashing back to that same card. These hardware ids are not changeable so you can't modify your card to match the other one.

I bought a 2017 TRD Pro recently and it didn't come with an SD card, and therefore no GPS. I'm pretty sure GPS was supposed to be included. How can I get this card? And get the dealership to pay for it?
