I agree the upgrade price is way too much. The 7.1 is NOT worth $300.

But those that bought their truck with the 6.1, got a fully functioning NAV system. There was no other disk available at the time.

Then they released the 7.1

They did not have you test a 7.1 NAV disk and then sell you a 6.1 disk, so they did not steal from you or cheat you.

They are however trying to steal from you by charging $300 for a disk that is worth maybee $50.

I was happy to get the 7.1 in my truck, but if it had the 6.1, I would have still bought it.
